12 goes into 11 0 times with 11 left over, so write 0 and a decimal point. Then bring down a zero and divide again, one digit at a time.
| Step | Divide | Digit | Subtract | Remainder |
|---|---|---|---|---|
| 1 | 110 ÷ 12 | 9 | 110 − 108 | 2 |
| 2 | 20 ÷ 12 | 1 | 20 − 12 | 8 |
| 3 | 80 ÷ 12 | 6 | 80 − 72 | 8 |
Remainder 8 has come up before — it is what step 3 started from. From there the division can only produce the same digits again, so the digits from step 3 on repeat forever (shaded): 11/12 = 0.91(6).

Converting 11/12 to a decimal
A fraction is a division. 11/12 = 11 ÷ 12 = 0.91(6) (0.916667…). The decimal repeats forever, written 0.91(6) with the repeating digits bracketed. That happens because 12 factors into 2 × 2 × 3, which includes a prime other than 2 or 5 — so no power of ten is divisible by it and the long division never terminates.
In metric that is 23.2833 millimetres (2.32833 cm), since one inch is exactly 25.4 mm. As a percentage of an inch it is 91.6667%.
11/12 is not a mark on any imperial rule — the denominators on a rule are all powers of two, and 12 is not one. The nearest marks are 15/16 on a 1/16 rule, 29/32 on a 1/32 rule, 59/64 on a 1/64 rule, none of them exact.
Going the other way
To turn 0.916667 back into a fraction, pick the precision you are working to and multiply. At 1/16: 0.916667 × 16 = 14.6667, giving 15/16 after rounding to the nearest mark. At 1/32: 0.916667 × 32 = 29.3333, giving 29/32 after rounding to the nearest mark. At 1/64: 0.916667 × 64 = 58.6667, giving 59/64 after rounding to the nearest mark.
