Begin checking the answer by multiplying the quotient by the divisor. The divisor is the number that you are dividing by. Multiply each number on the top by each number on the bottom.
Write the answers to multiplying the top numbers by the bottom number's ones place under the multiplication problem. Write the answers to multiplying the top numbers by the bottom number's tens place below the answer for the one's place answer.
Add these two answers together. If there is any remainder, add the remainder to this sum. The final sum should be the exact same as the dividend from the original division problem. The dividend is the number that is being divided.
