1. Repeated Subtraction: Division

2. Repeated subtraction
What is repeated subtraction?
It is subtracting until we reach 0 or until we can’t subtract any more.

3. Dividing using repeated subtraction
Rules for repeated subtraction
Step 1: we will subtract the dividend by the divisor. So 45 ÷ 9 = – 9
Step 2: keep subtracting the divisor until you can’t subtract anymore.
Step 3: count how many times you subtracted the divisor.

4. Step 1
Step 1: we will subtract the dividend by the divisor.
32 ÷ 8 =
Dividend is 32 and divisor is 8.
32 – 8 = 24

5. Step 2
Step 2: keep subtracting the divisor until you can’t subtract anymore.
32 ÷ 8 =
32 – 8 = 24
= 16
= 8
8 - 8 = 0

6. Step 3
Step 3: count how many times you subtracted the divisor.
32 ÷ 8 =
32 – 8 =
24 – 8 =
16 – 8 =
8 – 8 =
We subtracted 8 how many times?
So our answer is…..

7. Let’s try this together
49 ÷ 7 =
What is step 1?
What is step 2?
What is step 3?

8. Let’s try this together
81 ÷ 9 =
Step 1:
Step 2:
Step 3:

9. Try it on your own
27 ÷ 9 =
27 – 9 = 18
18 – 9 = 9
9 – 9 = 0
How many times did we subtract 9?

10. Try it on your own
56 ÷ 8 =7

11. Try it on your own
30 ÷ 5 =
