First lets have a simple division problem:
9 divided by 3, it is pretty easy so first just ask your self how many times can 3 go in to 9. You can see by doing this.....you have to multiply by 3. So, 3x1, no, that equals 3. Try 3x2, that doesn't equal 9, so try 3x3 and that equals 9 so in the end 3 divided by 9 equals 3.
Hope this helps!
