Long Division Steps • DAD (Divide) • MOM (Multiply) • SISTER (Subtract) • BROTHER (Bring Down) • ROVER (Repeat/Remainder)

This is a sample long division problem Quotient Divisor Answer Number doing the dividing. Dividend 148 r 4 6 892 -6 29 -2 4 52 -4 8 4 Number being divided

DAD (divide) 1. Divide 8 by 6 2. 6 goes into 8 once, so put 1 above the 8. 3. 6 goes into 29 4 times. 4. 6 goes into 52 8 times. 148 r 4 6 8 9 2 Dad -6 Mom 29 Sister -2 4 Brother 5 2 Rover -4 8 4

MOM (multiply) 1. After you divide 6 into 8 one time, you will multiple 1 x 6 and write it under the 8. 2. You will do this step after each time you divide. 148 r 4 6 8 9 2 Dad Mom -6 Sister 29 Brother -2 4 Rover 52 -4 8 4

SISTER (subtract) 1. After you multiply 1 x 6 you will subtract 8 - 6 which equals 2. 2. After each time you multiply, you will subtract the two numbers. 148 r 4 6 8 9 2 Dad Mom -6 Sister 2 9 Brother -2 4 Rover 52 -4 8 4

BROTHER (bring down) 1. After subtracting, you need to look back to the dividend to see if there are more numbers to bring down. If so move the number next to the subtracted number. 148 r 4 6 8 9 2 Dad Mom -6 Sister 29 Brother -2 4 Rover 52 -4 8 4

ROVER (repeat/remainder( 1. After you Divide, Multiply, Subtract, and Bring Down, you start the process over until there are no more numbers to bring down. 2. If there is a number other then ‘ 0’ after the last time you subtract, that number becomes your remainder. 148 r 4 6 892 -6 29 -2 4 52 -4 8 4 Reflection Dad Mom Sister Brother Rover
