We look at the division of 90036145 by 85 
We're looking to find how many times 85 goes into 90036145.

On to step 1:
The number 85 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 85

Going ahead to step 2:
The number 85 fits into 90 1 times, leaving a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 85 away from 90, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 85

On to step 3:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 50 and we're left with 50.
Include the next digit (3) from the dividend after 50, then repeat: 503 / 85

On to step 4:
85 can be fit into 503 5 times, resulting in a remainder of 78.
Write down 5 as next digit of the result. 
Result so far: 105.0
Subtracting 425 from 503 leaves us with 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 85

Going ahead to step 5:
When dividing 786 by 85, we get 9 with a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 1059.0
Deduct 765 from 786 and we're left with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 85

Going ahead to step 6:
When dividing 211 by 85, we get 2 with a remainder of 41.
Record the quotient 2 as the next digit in the result. 
Result so far: 10592.0
If we take 170 away from 211, we end up with 41.
Fetch the next digit (4) from the dividend, attach it to 41 and continue: 414 / 85

Going ahead to step 7:
When dividing 414 by 85, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 105924.0
Subtract 340 from 414 to get 74.
Take the next digit (5) from the dividend and append it to 74, then repeat: 745 / 85

On to step 8:
85 goes into 745 8 times with a remainder of 65.
Put 8 as the next digit of the answer. 
Result so far: 1059248.0
If we take 680 away from 745, we end up with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 9:
85 goes into 650 7 times with a remainder of 55.
Record the quotient 7 as the next digit in the result. 
Result so far: 1059248.7
Subtract 595 from 650 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
If we divide 550 by 85, we get 6 and a remainder of 40.
Write down 6 as next digit of the result. 
Result so far: 1059248.76
If we take 510 away from 550, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
85 goes into 400 4 times with a remainder of 60.
Put 4 as the next digit of the answer. 
Result so far: 1059248.764
Subtract 340 from 400 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 12:
When dividing 600 by 85, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 1059248.7647
Subtracting 595 from 600 leaves us 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 13:
85 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 1059248.7647
If we take 0 away from 50, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 14:
85 goes into 500 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1059248.764705
Subtract 425 from 500 to get 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 15:
When dividing 750 by 85, we get 8 with a remainder of 70.
Write down 8 as next digit of the result. 
Result so far: 1059248.7647058
Subtract 680 from 750 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 16:
The number 85 fits into 700 8 times, leaving a remainder of 20.
Record the quotient 8 as the next digit in the result. 
Result so far: 1059248.76470588
If we take 680 away from 700, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 1059248.76470588, with a leftover of 2e-08.
