We look at the division of 4000 by 85 
We want to divide 4000 by 85.

On to step 1:
The number 85 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 85

Step 2:
85 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 85

Going ahead to step 3:
When dividing 400 by 85, we get 4 with a remainder of 60.
Write down 4 as next digit of the result. 
Result so far: 4.0
Deduct 340 from 400 and we're left with 60.
Bring next digit (0) of the dividend behind the 60 and repeat the process: 600 / 85

Let's proceed to step 4:
When dividing 600 by 85, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 47.0
If we take 595 away from 600, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 5:
85 can be fit into 50 0 times, resulting in a remainder of 50.
The next digit of our result is 0. 
Result so far: 47.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 6:
The number 85 fits into 500 5 times, leaving a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 47.05
If we take 425 away from 500, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

On to step 7:
If we divide 750 by 85, we get 8 and a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 47.058
The remainder is 70 after subtracting 680 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 8:
If we divide 700 by 85, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 47.0588
Subtract 680 from 700 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 47.0588 and a remainder of 0.0002.
