Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 4

Step 4:
4 goes into 32 8 times with a remainder of 0.
Write down 8 as next digit of of the result. 
Result so far: 308
Subtract 32 from 32 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 4

Step 5:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of of the result. 
Result so far: 3080
