Subtract 15 from 17 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 5

Step 4:
5 goes into 28 5 times with a remainder of 3.
Write down 5 as next digit of of the result. 
Result so far: 335
Subtract 25 from 28 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 5

Step 5:
5 goes into 30 6 times with a remainder of 0.
Write down 6 as next digit of of the result. 
Result so far: 3356
Subtract 30 from 30 to get 0.

The final result is 3356 with a remainder of 0.
