Long Division Song | 2 Digit Divisor Version

Join Stu & friends at the beach in this long division song and music video as he explains how do divide with 2 digit divisors by drawing problems into the sand with his math-e-magic wand (a piece of driftwood)! He'll be using the standard algorithm - a concept usually taught and reinforced in the 5th & 6th Grade. Pull up a beach chair, turn the volume to eleven, and have your flip flops ready, because this Caribbean tune will rock your socks off!

Song Lyrics:

First divide the divisor by the dividend, we can fit one 14 into 27.
Then multiply one by the 14. Write the 14 and subtract, the difference is 13.
Then bring down the three, and the process will repeat
When we do long division we drop the beat!

Divide multiply subtract bring down that's how a quotient is found

Divide 133 By 14; first estimate in your minds.
Hmmm, I think we should try at nine.
Multiply 9 by 14 with this mental math trick, the product you will find is 126.
Subtract and the remainder is seven.
So write a seven in the quotient with an "R" present

Divide multiply subtract bring down that's how a quotient is found
Divide multiply subtract bring down
(And when there's a remainder write "R" followed by what's left over)
that's how a quotient is found

Now let’s see what the remainder really means
“R7” can be written as seven fourteenths
Since fourteen is the divisor, it’s the whole
The remainder is the part and that is its role.
So nineteen and seven fourteenths is the quotient,
and nineteen and a half is its equivalent (and it’s simplest form)!

Divide multiply subtract bring down that's how a quotient is found
Divide multiply subtract bring down
(The remainder can become the numerator, the divisor can become the denominator.)
that's how a quotient is found

G’day there, I'm Slater the Alligator from the land down under,
here to talk to you about long division with decimal numbers:
If there's only a decimal number in the dividend, simply do the division as you normally would. Then bring the decimal point straight up above the line to the quotient.

If the divisor is a decimal number, simply multiply it by ten (moving the decimal point to the right) until the decimal point is to the right of the divisor. Multiply the dividend by ten (moving the decimal point to the right) as many times as you multiplied the divisor by ten (moving the decimal point to the right and adding zeroes, if needed, when the original number doesn't have enough digits. Then divide as usual.)

Finally, remember to always check your division with multiplication, the inverse operation.
All right, Hoo-Roo for now!
