Math worksheet for practicing division by multiples of 10.

Let’s solve each division problem step by step. We’ll go one at a time, and I’ll show you how to think about dividing by multiples of 10 — it’s easier than it looks!

When you divide by 10, 20, 30, etc., you can often simplify by canceling zeros or breaking the numbers into smaller parts.

Left Column:

1. 420 ÷ 10 = ?
→ Just remove one zero from 420 → 42

2. 4,200 ÷ 10 = ?
→ Remove one zero → 420

3. 4,200 ÷ 100 = ?
→ Remove two zeros → 42

4. 42,000 ÷ 100 = ?
→ Remove two zeros → 420

5. 40 ÷ 10 = ?
→ Remove one zero → 4

6. 840 ÷ 10 = ?
→ Remove one zero → 84

7. 8,400 ÷ 10 = ?
→ Remove one zero → 840

8. 8,400 ÷ 100 = ?
→ Remove two zeros → 84

9. 84,000 ÷ 100 = ?
→ Remove two zeros → 840

10. 900 ÷ 10 = ?
→ Remove one zero → 90

11. 900 ÷ 30 = ?
→ Think: 900 ÷ 30 = (90 ÷ 3) = 30
*(Because 900 ÷ 10 = 90, then 90 ÷ 3 = 30)*

12. 6,000 ÷ 100 = ?
→ Remove two zeros → 60

13. 6,000 ÷ 200 = ?
→ 6,000 ÷ 200 = (60 ÷ 2) = 30
*(Divide both by 100 first: 60 ÷ 2)*

14. 240 ÷ 10 = ?
→ Remove one zero → 24

15. 240 ÷ 20 = ?
→ 240 ÷ 20 = (24 ÷ 2) = 12

16. 6,300 ÷ 100 = ?
→ Remove two zeros → 63

17. 6,300 ÷ 300 = ?
→ 6,300 ÷ 300 = (63 ÷ 3) = 21

Right Column:

18. 840 ÷ 40 = ?
→ 840 ÷ 40 = (84 ÷ 4) = 21

19. 3,600 ÷ 30 = ?
→ 3,600 ÷ 30 = (360 ÷ 3) = 120

20. 3,600 ÷ 300 = ?
→ Remove two zeros from both → 36 ÷ 3 = 12

21. 4,800 ÷ 20 = ?
→ 4,800 ÷ 20 = (480 ÷ 2) = 240

22. 4,800 ÷ 200 = ?
→ Remove two zeros → 48 ÷ 2 = 24

23. 69,000 ÷ 300 = ?
→ Remove two zeros → 690 ÷ 3 = 230

24. 800 ÷ 40 = ?
→ 800 ÷ 40 = (80 ÷ 4) = 20

25. 1,200 ÷ 40 = ?
→ 1,200 ÷ 40 = (120 ÷ 4) = 30

26. 1,280 ÷ 40 = ?
→ 1,280 ÷ 40 = (128 ÷ 4) = 32

27. 1,600 ÷ 400 = ?
→ Remove two zeros → 16 ÷ 4 = 4

28. 8,000 ÷ 200 = ?
→ Remove two zeros → 80 ÷ 2 = 40

29. 14,000 ÷ 200 = ?
→ Remove two zeros → 140 ÷ 2 = 70

30. 14,600 ÷ 200 = ?
→ Remove two zeros → 146 ÷ 2 = 73

31. 2,560 ÷ 80 = ?
→ 2,560 ÷ 80 = (256 ÷ 8) = 32

32. 16,100 ÷ 700 = ?
→ Remove two zeros → 161 ÷ 7 = 23
*(7 × 23 = 161)*

33. 14,400 ÷ 60 = ?
→ 14,400 ÷ 60 = (1,440 ÷ 6) = 240

34. 37,800 ÷ 900 = ?
→ Remove two zeros → 378 ÷ 9 = 42
