1/2 as a decimal

How to convert this fraction

Divide 1 by 2 using integer long division. The whole-number part is 0; the remaining fraction is 1/2.

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

The remainder reaches zero after 1 decimal places, so 1/2 = 0.5 exactly.

Check: 0 × 2 + 1 = 1, so the quotient and remainder reconstruct the original fraction.
