We're dividing 80972771 by 851 
We want to divide 80972771 by 851.

Step 1:
851 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 851

Step 2:
80 divided by 851 is 0 with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (9) from the dividend and append it to 80, then repeat: 809 / 851

On to step 3:
The number 851 fits into 809 0 times, leaving a remainder of 809.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 809 and we're left with 809.
Take the next digit (7) from the dividend and append it to 809, then repeat: 8097 / 851

Let's proceed to step 4:
The number 851 fits into 8097 9 times, leaving a remainder of 438.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7659 from 8097 to get 438.
Bring next digit (2) of the dividend behind the 438 and repeat the process: 4382 / 851

Advancing to step 5:
4382 divided by 851 is 5 with a remainder of 127.
Write down 5 as next digit of the result. 
Result so far: 95.0
Subtract 4255 from 4382 to get 127.
Fetch the next digit (7) from the dividend, attach it to 127 and continue: 1277 / 851

On to step 6:
If we divide 1277 by 851, we get 1 and a remainder of 426.
The number 1 becomes the next digit in our result. 
Result so far: 951.0
Subtract 851 from 1277 to get 426.
Grab the next digit (7) from the dividend, add it to 426, then carry on: 4267 / 851

Going ahead to step 7:
The number 851 fits into 4267 5 times, leaving a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 9515.0
Subtracting 4255 from 4267 leaves us with 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 851

On to step 8:
When dividing 121 by 851, we get 0 with a remainder of 121.
Write down 0 as next digit of the result. 
Result so far: 95150.0
The remainder is 121 after subtracting 0 from 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

Let's proceed to step 9:
851 can be fit into 1210 1 times, resulting in a remainder of 359.
Put 1 as the next digit of the answer. 
Result so far: 95150.1
Deduct 851 from 1210 and we're left with 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

Let's proceed to step 10:
If we divide 3590 by 851, we get 4 and a remainder of 186.
The next digit of our result is 4. 
Result so far: 95150.14
If we take 3404 away from 3590, we end up with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Step 11:
851 goes into 1860 2 times with a remainder of 158.
The number 2 becomes the next digit in our result. 
Result so far: 95150.142
If we subtract 1702 from 1860, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Advancing to step 12:
851 can be fit into 1580 1 times, resulting in a remainder of 729.
Write down 1 as next digit of the result. 
Result so far: 95150.1421
The remainder is 729 after subtracting 851 from 1580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7290, and continue the process.

Step 13:
If we divide 7290 by 851, we get 8 and a remainder of 482.
Record the quotient 8 as the next digit in the result. 
Result so far: 95150.14218
If we take 6808 away from 7290, we end up with 482.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4820, and continue the process.

Moving on to step 14:
When dividing 4820 by 851, we get 5 with a remainder of 565.
Write down 5 as next digit of the result. 
Result so far: 95150.142185
Deduct 4255 from 4820 and we're left with 565.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5650, and continue the process.

Let's proceed to step 15:
851 can be fit into 5650 6 times, resulting in a remainder of 544.
The number 6 becomes the next digit in our result. 
Result so far: 95150.1421856
Deduct 5106 from 5650 and we're left with 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Advancing to step 16:
5440 divided by 851 is 6 with a remainder of 334.
Put 6 as the next digit of the answer. 
Result so far: 95150.14218566
Deduct 5106 from 5440 and we're left with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

The final outcome is 95150.14218566, with a leftover of 3.34e-07.
