  1. Simplify: 15/51 = 5/17 (divide by 3)
  2. Divide the numerator by the denominator: 15 ÷ 51 = 0.29411765
  3. The digits in brackets repeat forever: 0.(2941176470588235)
  4. Check: Work backwards: 0.294118 × 51 = 15, which is 15 once rounding is allowed for.

In a spreadsheet: =15/51. Dividing the denominator by the numerator flips the fraction. A bar over (or brackets around) digits means they repeat forever.
