Long Division Algorithm
To be really good at division, you must learn your multiplication facts. For this lesson, if you don’t know them, you may want to use a multiplication chart like this one:
Vocabulary
• dividend - the number you are dividing
• divisor - the number you are dividing by
• quotient - the evenly divided result
• remainder - what is left over that cannot be evenly divided
• divisable- can be divided by evenly
When writing it like this:
136, is the dividend
5, is the divisor 27, is
the quotient
1 is the remainder1365

Math Fun:
Is it a simple task? Find the missing numbers as fast as you can!

Answer:
The missing numbers are 336, 504, 720. The pattern is: Multiply the first three whole numbers, the next three whole numbers, and so on.0 x 1 x 2 = 01 x 2 x 3 = 62 x 3 x 4 = 24, and so on.
