Division partitions a multi-digit whole number into equal groups of a one-digit size, relating the dividend, divisor, quotient, and any remainder through multiplication and subtraction. Place-value reasoning supports the standard algorithm, including regrouping, estimating to check reasonableness, and recording zeros when a place contributes no groups; a remainder must be smaller than the divisor and may need interpretation in context. The scope is whole-number dividends and one-digit divisors, excluding decimal divisors, fractional quotients, and more advanced forms of division.
On this page:
Division finds how many equal groups the divisor can make from the dividend.
First, estimate:
So, the quotient should be close to .
Use place value and divide from left to right:
Look at .
goes into exactly times.
Subtract:
The belongs in the hundreds place of the quotient.
Bring down the from the tens place.
Since goes into zero times, record a in the quotient.
Bring down the from the ones place.
goes into one time.
Subtract:
The remainder is .
Therefore,
Check the answer using multiplication and addition:
The remainder, , is less than the divisor, , so the answer is reasonable.
