How do you divide 3 digit numbers with 2 digit numbers?

You just start with seeing how many times the 2 digit number can go into the 1st 2 numbers of the 3 digit number. Then you put how many times the 2 digit number can go into the 1st 2 digits of the 3 digit number up top.

It's called long division, which is basically a system of finding how many times you can take away the 2 digit number. Sometimes you can't do the first step above if the hundreds digit is too small. When that happens you just get a zero in that part of the calculation.

First deal with the hundreds & tens. Look at 144 divided by 12. The leftmost 2 digits represent 14 tens. You can divide this by 12 to get 1 ten in your answer and a remainder of 2 tens left over from the original 14 tens. Add this spare 2 tens to the 4 in the units column to get 24. This is now thought of as 24 units and you can divide this by 12 to get 2 units. Total answer = 1 ten plus 2 units =12. If you try to divide 108 by 12 then the first step won't go because you can't take 12 from 10. But you simply say the answer is zero with 10 left over. Add on the next bit as above to get 108 and you find you can take 9 twelves from it and get none left. So the answer is 09, or simply 9.
