We look at the division of 80911037 by 813 
Our goal is to divide 80911037 by 813.

Let's proceed to step 1:
813 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 813

On to step 2:
When dividing 80 by 813, we get 0 with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 813

On to step 3:
809 divided by 813 is 0 with a remainder of 809.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 809 and we're left with 809.
Append the next digit (1) from the dividend to 809 and continue with: 8091 / 813

Going ahead to step 4:
When dividing 8091 by 813, we get 9 with a remainder of 774.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 7317 from 8091 and we're left with 774.
Include the next digit (1) from the dividend after 774, then repeat: 7741 / 813

Step 5:
813 can be fit into 7741 9 times, resulting in a remainder of 424.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
The remainder is 424 after subtracting 7317 from 7741.
Fetch the next digit (0) from the dividend, attach it to 424 and continue: 4240 / 813

Step 6:
If we divide 4240 by 813, we get 5 and a remainder of 175.
The next digit of our result is 5. 
Result so far: 995.0
If we take 4065 away from 4240, we end up with 175.
Grab the next digit (3) from the dividend, add it to 175, then carry on: 1753 / 813

Going ahead to step 7:
1753 divided by 813 is 2 with a remainder of 127.
Put 2 as the next digit of the answer. 
Result so far: 9952.0
The remainder is 127 after subtracting 1626 from 1753.
Grab the next digit (7) from the dividend, add it to 127, then carry on: 1277 / 813

Step 8:
813 goes into 1277 1 times with a remainder of 464.
The number 1 becomes the next digit in our result. 
Result so far: 99521.0
If we subtract 813 from 1277, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Going ahead to step 9:
813 goes into 4640 5 times with a remainder of 575.
Write down 5 as next digit of the result. 
Result so far: 99521.5
Subtract 4065 from 4640 to get 575.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

Moving on to step 10:
813 can be fit into 5750 7 times, resulting in a remainder of 59.
The next digit of our result is 7. 
Result so far: 99521.57
The remainder is 59 after subtracting 5691 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 11:
If we divide 590 by 813, we get 0 and a remainder of 590.
The next digit of our result is 0. 
Result so far: 99521.57
The remainder is 590 after subtracting 0 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 12:
813 goes into 5900 7 times with a remainder of 209.
Write down 7 as next digit of the result. 
Result so far: 99521.5707
If we subtract 5691 from 5900, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Going ahead to step 13:
If we divide 2090 by 813, we get 2 and a remainder of 464.
Write down 2 as next digit of the result. 
Result so far: 99521.57072
Deduct 1626 from 2090 and we're left with 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Advancing to step 14:
If we divide 4640 by 813, we get 5 and a remainder of 575.
The number 5 becomes the next digit in our result. 
Result so far: 99521.570725
The remainder is 575 after subtracting 4065 from 4640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5750, and continue the process.

On to step 15:
The number 813 fits into 5750 7 times, leaving a remainder of 59.
Use 7 as the next digit of our solution. 
Result so far: 99521.5707257
The remainder is 59 after subtracting 5691 from 5750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 16:
If we divide 590 by 813, we get 0 and a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 99521.5707257
Subtract 0 from 590 to get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

After the division, we end up with 99521.5707257 and a remainder of 5.9e-07.
