To divide, we begin by realizing that 1 hundred can't be divided into seven pieces. Then we move to the tens place. We have 14 tens which can be divided into 7 with 2 tens, or 20, as the result. Finally we have 4, which cannot be divided by 7. Thus, the result is 20 R 4, 20 4/7. Thus seven goes into 144 20 times.
