Where the decimal comes from
There is no rewrite over 10, 100 or 1000 for 5/6: 6 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:
- 50 ÷ 6 = 8remainder 2
- 20 ÷ 6 = 3remainder 2— this remainder has come around before, so from here the digits repeat
Written exactly: 0.8(3) — the parentheses mark the block that repeats forever.
