Where the decimal comes from

There is no rewrite over 10, 100 or 1000 for 1/19: 19 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. 10 ÷ 19 = 0remainder 10
2. 100 ÷ 19 = 5remainder 5
3. 50 ÷ 19 = 2remainder 12
4. 120 ÷ 19 = 6remainder 6
5. 60 ÷ 19 = 3remainder 3
6. 30 ÷ 19 = 1remainder 11— …and on it goes; the cycle takes 18 digits to close
