Where the decimal comes from

There is no rewrite over 10, 100 or 1000 for 9/14: 14 has a prime factor other than 2 and 5, so no whole-number multiplier reaches a power of ten. Watch the long division to see what happens instead — the remainders start circling, and once a remainder comes back, the digits must too:

  1. 90 ÷ 14 = 6remainder 6
  2. 60 ÷ 14 = 4remainder 4
  3. 40 ÷ 14 = 2remainder 12
  4. 120 ÷ 14 = 8remainder 8
  5. 80 ÷ 14 = 5remainder 10
  6. 100 ÷ 14 = 7remainder 2— …and on it goes; the cycle takes 6 digits to close

Written exactly: 0.6(428571) — the parentheses mark the block that repeats forever.
