4th grade twodigit division is the foundation of what you will learn in this grade math curriculum. But in fact, many children still miscalculate this type of exercise, so the following article Trường THPT Trần Hưng Đạo will reveal the secrets to learning more accurate 2digit division knowledge that children can refer to and apply.
The knowledge to prepare when learning the division of two digits in grade 4
Before starting to study 4th grade math, division by twodigit numbers, students need to understand the following knowledge:
Reviewing the division multiplication table
The multiplication table is the most basic and important foundation when you learn multiplication or division that you will learn from the 2nd grade math curriculum. So, to solve the twodigit division problem, it is necessary to solve the multiplication problem. Master the multiplication table from 1 to 10.
Mastering the knowledge of 1digit division
Before you learn about twodigit division, you need to understand how to do 1digit division.
We will take the following example to better understand the calculation of division by 1 digit.
For example: 21024 : 2 = ?
We perform the division in order from left to right. Simultaneously apply 3 steps: division – multiplication – subtraction.
– 2 divided by 2 equals 1, write 1
1 times 2 equals 2, 2 minus 2 equals 0
– Lower 1, 1 cannot be divided by 2, write 0
0 times 2 equals 0, 1 minus 0 equals 1
– Lower 0 get 10, 10 divide 2 get 5, write 5
5 times 2 equals 10, 10 minus 10 equals 0
– Lower 2, 2 divide 2 get 1, write 1
1 times 2 gets 2, 2 minus 2 equals 0
– Lower 4, 4 divided by 2 get 2, write 2
2 times 2 equals 4, 4 minus 4 equals 0
So 21024 : 2 = 10512
Distinguish division without remainder and with remainder
In addition, in the division calculation, it is also divided into division with remainder and without remainder, so you also need to understand this feature to perform the calculation more accurately. Here’s how to differentiate division with remainder and without remainder in detail:
 No remainder division: This is a division with a remainder of 0
For example: Mom has 10 oranges to divide into 2 baskets, each basket has 5 apples.
We have division: 10:2
We say: 10:2 is divisibility with quotient of 5
 Division with remainder: This is a division with remainder 0 < remainder < divisor
For example: Mother has 7 apples divided equally into 2 baskets, each basket has 3 apples, she has 1 left over.
We have division: 7:2
We say: 7:2 is division with remainder, quotient is 3, remainder 1
Review rows and classes of natural numbers
In division, students are required to place the equivalent numbers in rows and classes together. Therefore, children need to understand the row and class knowledge of natural numbers, including:

Hundreds, tens, and units form the unit class

Hundreds of thousands, tens of thousands, thousands make up the class of thousands
Instructions for performing 4th grade math division by two digit numbers
After fully equipped with knowledge to help children understand basic division with one digit, here are the steps to perform twodigit division in grade 4 for them to learn:

Step 1: Put the calculation in the vertical column like a normal 1digit division calculation

Step 2: Take the first 2 digits of the divisor and divide by the divisor. At this time, how much quotient you get, multiply by the opposite of the divisor. Then subtract the product from the first 2 digits. Note: If the first 2 digits of the divisor are smaller than the divisor, the first 3 digits of the divisor must be taken and divided by the divisor, and then also multiplied and subtracted in the same way as above.

Step 3: Keep the number you just received, and then lower the next number of the divided number down to units to get a new number. Continue dividing that number by the divisor to get the next quotient, then multiply the quotient received by the divisor, continue to subtract the original new number for the product received.

Step 4: Continue to lower the numbers of the divided number in order from left to right, and perform the same calculation steps as step 3 until the number of units is exhausted.
At this point, the quotient sequence received is the result of the 2digit division calculation that you need to find. The end result can be divisibility or division with remainder.
Note:
 When performing a division calculation, the digits of the number are divided from left to right.
 The final remainder is always less than the divisor
 Divisibility if remainder is 0
For example: 428 : 24 = ?
Step 1: Divide 42 by 24 to get 1
Multiply 1 by 24 to get 24; 42 minus 24 gets 18
Step 2: Keeping 18, lower the next digit to the right of the divisor, the number 8. I got the new number 188
Divide 188 by 24 to get 8
Multiply 8 by 24 to get 184; 188 minus 184 is 4
So: 428 : 24 = 18 and the remainder is 4
A type of exercise from basic to advanced on division by 2 digit numbers
In the 4th grade math program, with the division of two digits, you will often encounter the following basic types of exercises:
Form 1: Exercises to calculate and then calculate
Solution method: Students will put the calculation in the vertical column, perform the calculation from left to right and apply the steps to solve the division calculation as analyzed above.
Example 1: 840 : 35
Solution guide:
Step 1: Divide 84 by 35 to get 2
Multiply 2 by 35 to get 70; 84 minus 70 gets 14
Step 2: Keeping 14, lower the next digit to the right of the divisor, which is zero. I got the new number 140
Divide 140 by 35 to get 4
Multiply 4 by 35 to get 140
So: 840 : 35 = 24
Example 2: 352 : 27 = ?
Step 1: Divide 35 by 27 to get 1
Multiply 1 by 27 to get 27; 35 minus 27 gets 8
Step 2: Keeping 8, lower the next digit to the right of the divisor is 2. I got the new number 82
Divide 82 by 27 to get 3
Multiply 3 by 27 to get 81 remainder 1
So: 352 : 27 = 13 remainder 1
Form 2: Applied problems
Solution method: Depending on each problem, students must read the problem carefully to be able to perform the calculation and come up with the correct solution.
Example: A flock of ducks a day produces 780 eggs. The farmer harvests eggs every day and divides them into dozens of different eggs. Each dozen eggs are sold for 24,000 VND. So how much money does the farmer earn from eggs a day? Know that each dozen has 12 fruits.
The answer:
The number of dozen eggs that the farmer can harvest each day is:
780 : 12 = 65 (dozen eggs)
The amount of eggs that the farmer collects each day is:
65 x 24,000 = 1,560,000 VND
Answer: So every day the farmer earns 1,560,000 VND from harvesting duck eggs.
