How do I do long division?

Long Division is one of those basic concepts that always seems for some students to be a difficult concept to master. This is a basic mnemonic device ( a way to remember) the steps to long division.

Does McDonalds Serve Burgers?

This is just one of the few mnemonic devices that I use to teach long division.

Does = Divide

McDonalds = Multiply

Serve = Subtract

Burgers = Bring Down



Let's look at the problem to the right to see how this works.


The first step is to DIVIDE. What is 2 ÷ 2 = 1. 1 goes on top of the problem.


Second step MULTIPLY. 1 x 2 = 2. 2 goes below the dividend.


Third step SUBTRACT. 2 - 2 = 0.


Final step BRING DOWN. Bring down the next number which is a 4.

Repeat!

Repeat Does McDonalds Serve Burgers Steps

We are going to continue to repeat the steps until the problem is done.

We just brought down the 4 so now we need to Divide. 4÷2 = 2. 2 goes in the quotient on top.

We multiply the digit we just placed in the quotient 2 by the divisor 2. 2 × 2= 4.

We place the product below to create a subtraction problem. 4 - 4 = 0

Bring Down the next digit 6.

Repeat the steps again to finish the problem.

      Thanks! This is the one I was taught as a child, but as an activity I also have the students try and create their own with the same letters.

      That is thoughtful I must say! You must be a gem of a teacher then! Helping kids shape up their own imagination is what I would dream my teacher to be like! Hats off!

      I must insist that you share your tricks and techs with us from time to time!

      I have quite a few math hubs already and will be adding daily as I have time.

      Nice Hub! You can make nice math markup for future hubs by using the LaTeX equation editor at codecogs.com/latex/eqneditor.php and then right-click and save the image as a gif or png. It's not too hard a language to learn. for instance, to make a nice picture of ( 3 / sqrt( 4^2 + x ) ), you'd type "\frac{3}{\sqrt{4^2 + x}}" without the quotes. Note that the combo box that says "transparent" should be set to white for it to look good in most cases.

      Thanks! I will try it out, I use a lot of screen shot type elements to create my images.

      Anything I can try to get students to do long division is worth looking at.

      Good morning, kthix10, I am sharing this hub and pinning as well. I am also placing this link in a hub I am publishing about math in the next few days. Hats off to you. voted up
