Title: Division

Grade: 4-a Lesson: S2-L4

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

Examples:

Divide 620 ÷ 5

Step 1a

Draw the division symbol ⟌ and write divisor 5 is on left side and dividend 620 closed under this symbol.

$1a$

Explanation: Arrange the numbers in division form:

Step 1b

6 is divisible by 5 but since 5 × 1 = 5. we go for it.
Subtract 6 - 5 = 1 and write 1 in the Quotient.

$1b$

Explanation: Here, the first digit of the dividend is 6, 6 is divisible by 5. Subtract 6 - 5 = 1 and write quotient is 1.

Step 1c

Now, bring down the next value to 2.
The number to be considered now is 12.
12 is not divisible by 5 but since 5 × 2 = 10, subtract 12 - 10 = 2,and write 2 in the quotient.
Therefore 12 ÷ 5 = 2.

$1c$

Explanation: In this step, bring down the next value, 2, and write it next to 12. Since 12 is divisible by 5, we divide 12 by 5 to get 2 and then subtract 12 from 10, resulting in 2. Hence, 12 divided by 5 is 2.

Step 1d

Now, bring down the next value to 0. The number to be considered now is 20.
20 is not divisible by 5, but since 5 × 4 = 20, subtract 20 - 20 = 0,and write 4 in the Quotient.
Therefore the quotient = 124. and the remainder is 0.

$1d$

Explanation: In this step, bring down the next value, 0, and write it next to 20. Since 20 is divisible by 5, we divide 20 by 5 to get 4 and then subtract 20 from 20, resulting in 0. Hence, 620 divided by 5 is 124.
