How to turn 5/8 into a decimal

Divide the top number by the bottom one: 5 ÷ 8. 8 does not go into 5, so write 0 and a decimal point, put a 0 after the 5 and divide:

  1. 50 ÷ 8 = 6, remainder 2 (6 × 8 = 48)
  2. Bring down a 0: 20 ÷ 8 = 2, remainder 4 (2 × 8 = 16)
  3. Bring down a 0: 40 ÷ 8 = 5, remainder 0 (5 × 8 = 40). Remainder 0, so the division ends: 5/8 = 0.625

To read it as a percentage, move the decimal point two places to the right: 62.5%.
