Long division, step by step

Divide the numerator by the denominator the way it is done on paper: bring down a zero, note how many times the denominator fits, keep the remainder, repeat. The remainders are what decide whether the decimal stops.

StepWorkingDigitRemainder
113 × 10 = 13042
22 × 10 = 20020
320 × 10 = 20068
48 × 10 = 80216
516 × 10 = 16050

The remainder reaches zero at step 5, which is precisely why the decimal terminates. A zero remainder means nothing is left to carry down.

Rounded to different precisions

How many places you keep depends on the use: money stops at two, engineering often wants three or four, and a science problem usually wants significant figures rather than decimal places.

Will it terminate?

A fraction has a terminating decimal exactly when its simplified denominator is built only from 2s and 5s. Here the denominator reduces to 32, which factors to 25 — nothing but 2s and 5s, so the decimal stops. This is a property of the denominator alone: the numerator never decides it.

Questions about 13/32

What is 13/32 as a decimal?

Exactly 0.40625. The division terminates because the reduced denominator 32 has no prime factors other than 2 and 5, so the decimal stops after 5 digits.

Is 13/32 already in simplest form?

Yes. 13 and 32 share no common factor, so the fraction cannot be reduced further and the decimal is generated from these exact digits.

How do I round 13/32 to two decimal places?

Two places give 0.41. The exact value is already closed at 5 digits, so rounding only pads or trims zeros rather than changing the value.

What is 13/32 as a percentage?

40.63%, obtained by multiplying the decimal by 100. It is the same number with the decimal point moved two places to the right, and the same rounding rules apply.
