Explanation:
We are using
chunking to divide numbers. Chunking means breaking the dividend (the big number) into parts that are easy to divide by the divisor (the smaller number), then adding up how many times the divisor fits into each part.
Let’s go one problem at a time.

Problem 2: 64 ÷ 4
We want to split 64 into chunks that are multiples of 4.
Try:
- 4 × 10 = 40 → subtract 40 from 64 → remainder is 24
- 4 × 6 = 24 → subtract 24 → remainder is 0
So total: 10 + 6 =
16
Check: 4 × 16 = 64
✔

Problem 3: 90 ÷ 5
Split 90:
- 5 × 10 = 50 → remainder: 90 − 50 = 40
- 5 × 8 = 40 → remainder: 0
Total: 10 + 8 =
18
Check: 5 × 18 = 90
✔

Problem 4: 84 ÷ 6
Split 84:
- 6 × 10 = 60 → remainder: 84 − 60 = 24
- 6 × 4 = 24 → remainder: 0
Total: 10 + 4 =
14
Check: 6 × 14 = 84
✔

Problem 5: 91 ÷ 7
Split 91:
- 7 × 10 = 70 → remainder: 91 − 70 = 21
- 7 × 3 = 21 → remainder: 0
Total: 10 + 3 =
13
Check: 7 × 13 = 91
✔
---
Problem 6: 96 ÷ 8
Split 96:
- 8 × 10 = 80 → remainder: 96 − 80 = 16
- 8 × 2 = 16 → remainder: 0
Total: 10 + 2 =
12
Check: 8 × 12 = 96
