Title: Division

Grade: 4-a Lesson: S2-L1

Explanation: The best way to understand divisions is by looking at some examples. Take turns and read each example for easy understanding.

Examples:

Divide 610 ÷ 2

Step 1a

Draw the division symbol ⟌ and write divisor 2 is on left side and dividend 610 closed under this symbol.

$1a$

Explanation: Arrange the numbers in division form:

Step 1b

610 is divisible by 2, but since 2 × 3 = 6. We proceed with it. Subtract 6 - 6 = 0 and write 3 in the first Quotient.

$1b$

Explanation: In this step, 6 is divisible by 2. However, since 2 × 3 = 6, we proceed with it. Subtract 6 - 6 = 0 and write 3 in the first Quotient.

Step 1c

Now, bring down the next value, 1.
1 is not divisible by 2, so divide 1 by 2 to get 0, Write 0 in the quotient. Subtract 1 − 0 = 1

$1c$

Explanation: In this step, bring down the next value, 1, and write it next to 1. Since 1 is not divisible by 2, we divide 1 by 2 to get 0 and then subtract 1 from 0, resulting in 1. Hence, 1 divided by 2 is 1.

Step 1d

Now, bring down the next value to 0. The number to be considered now is 10.
10 is divisible by 2 but since 2 × 5 = 10, subtract 10 - 10 = 0,and write 5 in the quotient.
Therefore 610 ÷ 2 = 305.

$1d$

Explanation: In this step, bring down the next value, 0, and write it next to 10. Since 10 is divisible by 2, we divide 10 by 2 to get 5 and then subtract 10 from 10, resulting in 0. Hence, 610 divided by 2 is 305.
