Result so far: 0
Subtract 0 from 4 to get 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 5

Step 2:
5 goes into 42 8 times with a remainder of 2.
Write down 8 as next digit of of the result. 
Result so far: 8

Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 5

Step 3:
5 goes into 25 5 times with a remainder of 0.
Write down 5 as next digit of of the result. 
Result so far: 85
Subtract 25 from 25 to get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 5

Step 4:
5 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of of the result. 
Result so far: 850
Subtract 0 from 0 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 5

Step 5:
5 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of of the result. 
Result so far: 8500
Subtract 0 from 1 to get 1.

The final result is 8500 with a remainder of 1.
