We look at the division of 636159 by 85 
Our goal is to divide 636159 by 85.

Moving on to step 1:
6 divided by 85 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 85

Step 2:
If we divide 63 by 85, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Fetch the next digit (6) from the dividend, attach it to 63 and continue: 636 / 85

Step 3:
85 goes into 636 7 times with a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 595 from 636 to get 41.
Include the next digit (1) from the dividend after 41, then repeat: 411 / 85

Let's proceed to step 4:
The number 85 fits into 411 4 times, leaving a remainder of 71.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 340 from 411, we get 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 85

Moving on to step 5:
The number 85 fits into 715 8 times, leaving a remainder of 35.
Put 8 as the next digit of the answer. 
Result so far: 748.0
Subtract 680 from 715 to get 35.
Append the next digit (9) from the dividend to 35 and continue with: 359 / 85

Going ahead to step 6:
When dividing 359 by 85, we get 4 with a remainder of 19.
The next digit of our result is 4. 
Result so far: 7484.0
The remainder is 19 after subtracting 340 from 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
85 can be fit into 190 2 times, resulting in a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 7484.2
The remainder is 20 after subtracting 170 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
85 goes into 200 2 times with a remainder of 30.
Write down 2 as next digit of the result. 
Result so far: 7484.22
Subtract 170 from 200 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 7484.22, with a leftover of 0.03.
