➗📚As children learn more about division, they begin solving problems with larger numbers. When numbers are too big to divide easily in one step, we use a method called long division. Long division breaks a large division problem into smaller, simple steps, making it easier to solve.
Long division is a step-by-step method used to divide larger numbers.
Example:
84 ÷ 4
Instead of dividing the number all at once, we divide one digit at a time.
Many students remember long division using the phrase:
DMSB
1. Divide
2. Multiply
3. Subtract
4. Bring down
These steps repeat until the problem is finished.
Example: 84 ÷ 4
Step 1: Divide
8 ÷ 4 = 2
Step 2: Multiply
2 × 4 = 8
Step 3: Subtract
8 − 8 = 0
Step 4: Bring down
Bring down the 4
Now divide again:
4 ÷ 4 = 1
Final answer:
84 ÷ 4 = 21
Example: 96 ÷ 3
Step 1: Divide
9 ÷ 3 = 3
Step 2: Multiply
3 × 3 = 9
Step 3: Subtract
9 − 9 = 0
Step 4: Bring down
Bring down 6
6 ÷ 3 = 2
Answer:
96 ÷ 3 = 32
Problem 1
63 ÷ 3 = ___
Answer: 21
Problem 2
72 ÷ 4 = ___
Answer: 18
Problem 3
55 ÷ 5 = ___
Answer: 11
Learning long division helps children:
● Solve larger division problems
● Strengthen multiplication and subtraction skills
● Prepare for fractions, decimals, and algebra
Long division helps children divide larger numbers by breaking problems into smaller steps. By following the steps Divide, Multiply, Subtract, and Bring Down, students can solve division problems accurately and confidently.
