We look at the division of 97579140 by 809 
We want to divide 97579140 by 809.

Advancing to step 1:
When dividing 9 by 809, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (7) from the dividend, attach it to 9 and continue: 97 / 809

Moving on to step 2:
If we divide 97 by 809, we get 0 and a remainder of 97.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 97 and we're left with 97.
Grab the next digit (5) from the dividend, add it to 97, then carry on: 975 / 809

Advancing to step 3:
809 goes into 975 1 times with a remainder of 166.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 809 from 975, we get 166.
Bring next digit (7) of the dividend behind the 166 and repeat the process: 1667 / 809

Going ahead to step 4:
1667 divided by 809 is 2 with a remainder of 49.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 1618 from 1667 to get 49.
Take the next digit (9) from the dividend and append it to 49, then repeat: 499 / 809

Step 5:
809 goes into 499 0 times with a remainder of 499.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
Deduct 0 from 499 and we're left with 499.
Include the next digit (1) from the dividend after 499, then repeat: 4991 / 809

On to step 6:
809 goes into 4991 6 times with a remainder of 137.
The number 6 becomes the next digit in our result. 
Result so far: 1206.0
Subtract 4854 from 4991 to get 137.
Include the next digit (4) from the dividend after 137, then repeat: 1374 / 809

Advancing to step 7:
If we divide 1374 by 809, we get 1 and a remainder of 565.
Write down 1 as next digit of the result. 
Result so far: 12061.0
Subtract 809 from 1374 to get 565.
Take the next digit (0) from the dividend and append it to 565, then repeat: 5650 / 809

Advancing to step 8:
If we divide 5650 by 809, we get 6 and a remainder of 796.
The next digit of our result is 6. 
Result so far: 120616.0
If we subtract 4854 from 5650, we get 796.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7960, and continue the process.

Going ahead to step 9:
809 goes into 7960 9 times with a remainder of 679.
The number 9 becomes the next digit in our result. 
Result so far: 120616.9
If we subtract 7281 from 7960, we get 679.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6790, and continue the process.

Advancing to step 10:
809 goes into 6790 8 times with a remainder of 318.
Record the quotient 8 as the next digit in the result. 
Result so far: 120616.98
Subtracting 6472 from 6790 leaves us with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 11:
When dividing 3180 by 809, we get 3 with a remainder of 753.
Write down 3 as next digit of the result. 
Result so far: 120616.983
If we take 2427 away from 3180, we end up with 753.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7530, and continue the process.

Let's proceed to step 12:
When dividing 7530 by 809, we get 9 with a remainder of 249.
Put 9 as the next digit of the answer. 
Result so far: 120616.9839
The remainder is 249 after subtracting 7281 from 7530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2490, and continue the process.

Step 13:
809 can be fit into 2490 3 times, resulting in a remainder of 63.
The number 3 becomes the next digit in our result. 
Result so far: 120616.98393
Subtract 2427 from 2490 to get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Going ahead to step 14:
809 can be fit into 630 0 times, resulting in a remainder of 630.
Record the quotient 0 as the next digit in the result. 
Result so far: 120616.98393
Subtracting 0 from 630 leaves us with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Advancing to step 15:
809 goes into 6300 7 times with a remainder of 637.
The number 7 becomes the next digit in our result. 
Result so far: 120616.9839307
Subtract 5663 from 6300 to get 637.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6370, and continue the process.

Going ahead to step 16:
6370 divided by 809 is 7 with a remainder of 707.
The next digit of our result is 7. 
Result so far: 120616.98393077
If we subtract 5663 from 6370, we get 707.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7070, and continue the process.

The final result is 120616.98393077 with a remainder of 7.07e-07.
