4 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of of the result. 
Result so far: 360
Subtract 0 from 1 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Step 5:
4 goes into 15 3 times with a remainder of 3.
Write down 3 as next digit of of the result.
