please explain the proccess of learning "division" in common core math

With common core math, you will be breaking up a number to divide it. For instance, look at 420/3:

420 can be broken up into 300 and 120. We can easily see that 300/3=100, and we can see that 120/3=40.

If you add those two results, you'll have 140, which equals 420/3

I hope this helps explain common core math for you!
