Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 5

Step 4:
5 goes into 17 3 times with a remainder of 2.
Write down 3 as next digit of of the result. 
Result so far: 333
Subtract 15 from 17 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 5

Step 5:
5 goes into 22 4 times with a remainder of 2.
Write down 4 as next digit of of the result. 
Result so far: 3334
