so first you have to bring down the 3 so it is next to the six, and then you divide 36 by 15 and that equals 2. So you right a 2 on top. Then you have to multiply 2 and 15 and that equals 30 so you put a 30 below the 36. After you subtract, it equals 6 then you bring down the 1. Now you divide 61 and 15. The answer is 4 so you put a 4 on top next to the 2. After that you multiply 15 by 4 and that equals 60. You subtract 60 from 61, and you are left with a remainder of 1
