Important Terms
Quick Solve
Divisor: the number dividing into the
dividend
*
Put lines above each number on the top of the
division bracket
Dividend: the number being divided
Divide, Multiply, Subtract, Bring Down
(ignore the decimal point)
*
Quotient: the answer to a division
problem
*
Add zeros to the dividend until the answer
ends with no remainders (if needed)
Bring the decimal point straight up (if no
number is in front of the decimal put a zero)
Check your answer (use multiplication)

Notes and Examples
1. On the top of the division bracket: put lines above each number (this indicates how
many places should be in your quotient/answer)
_ _ _
12 4 9. 2 6
*12 cannot go into 4, so there will be no line above it. 12 can go into 49, so the first
line goes above the nine and goes above all of the following numbers
2. Divide, multiply, subtact, and bring down as if the decimal was not there. Ignore
until the decimal until the end.
3.Add zeros to the dividend (if needed.) Continue until bring down zeros one at a time
until you get a difference of zero. You cannot have a remainder.
