1/8 as a decimal

How to convert this fraction

Divide 1 by 8 using integer long division. The whole-number part is 0; the remaining fraction is 1/8.

1. Bring down a zero: remainder × 10 gives the next decimal digit 1; the new remainder is 2.
2. Bring down a zero: remainder × 10 gives the next decimal digit 2; the new remainder is 4.
3. Bring down a zero: remainder × 10 gives the next decimal digit 5; the new remainder is 0.

The remainder reaches zero after 3 decimal places, so 1/8 = 0.125 exactly.

Check: 0 × 8 + 1 = 1, so the quotient and remainder reconstruct the original fraction.
