How to turn 5/16 into a decimal

Divide the top number by the bottom one: 5 ÷ 16. 16 does not go into 5, so write 0 and a decimal point, put a 0 after the 5 and divide:

  1. 50 ÷ 16 = 3, remainder 2 (3 × 16 = 48)
  2. Bring down a 0: 20 ÷ 16 = 1, remainder 4 (1 × 16 = 16)
  3. Bring down a 0: 40 ÷ 16 = 2, remainder 8 (2 × 16 = 32)
  4. Bring down a 0: 80 ÷ 16 = 5, remainder 0 (5 × 16 = 80). Remainder 0, so the division ends: 5/16 = 0.3125

To read it as a percentage, move the decimal point two places to the right: 31.25%.
