Long Division - How It Works
Here is a simple explanation of Long Division.
Start at the "high end" (these examples start at the 100s) and then work down to the units.
Drag and Drop the 100s, then the 10s, then the 1s, and see how the Long Division is done.
Note: this is what I call "Beginners Long Division", because we write out the whole subtraction each time. But when you "get the idea" of what is happening you can move on to the normal method explained here.
