Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 8

Step 4:
8 goes into 31 3 times with a remainder of 7.
Write down 3 as next digit of of the result. 
Result so far: 233
Subtract 24 from 31 to get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 8

Step 5:
8 goes into 79 9 times with a remainder of 7.
Write down 9 as next digit of of the result. 
Result so far: 2339
Subtract 72 from 79 to get 7.

The final result is 2339 with a remainder of 7.
