Understand the problem
You want to divide 45.6 by 20.
Remove the decimal for easier division
Multiply both numbers by 10 to get whole numbers:
45.6 × 10 = 456
20 × 10 = 200
Now divide 456 ÷ 200.
Do the division
200 goes into 456 two times because:
200 × 2 = 400 (less than 456)
200 × 3 = 600 (too big)
Find the remainder
456 – 400 = 56
Step 5: Convert remainder to decimal
Remainder 56 out of 200 = 56 ÷ 200 = 0.28
Add this to the whole number:
2 + 0.28 = 2.28
answer: 45.6 ÷ 20 = 2.28
