Set up and complete a long division problem for a multi-digit dividend.
Turn a remainder into a decimal quotient instead of leaving it as a leftover.
Check a division answer by multiplying the quotient by the divisor.
What the lesson concludes
The dividend goes inside the bracket, the divisor goes outside it, and the quotient is built one digit at a time from left to right.
Each step is the same small loop: estimate, multiply, subtract, bring down.
A leftover remainder is not the final answer. Place a decimal point after the dividend, bring down zeros, and keep going until it terminates or you can round sensibly.
Multiply the quotient by the divisor to check your work; it should reproduce the dividend.
