Let's divide 80680961 by 857
Our goal is to divide 80680961 by 857.

Advancing to step 1:
The number 857 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 857

Moving on to step 2:
857 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 857

Going ahead to step 3:
806 divided by 857 is 0 with a remainder of 806.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 806 and we're left with 806.
Grab the next digit (8) from the dividend, add it to 806, then carry on: 8068 / 857

Moving on to step 4:
8068 divided by 857 is 9 with a remainder of 355.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 355 after subtracting 7713 from 8068.
Append the next digit (0) from the dividend to 355 and continue with: 3550 / 857

Going ahead to step 5:
The number 857 fits into 3550 4 times, leaving a remainder of 122.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
Subtracting 3428 from 3550 leaves us with 122.
Take the next digit (9) from the dividend and append it to 122, then repeat: 1229 / 857

Going ahead to step 6:
If we divide 1229 by 857, we get 1 and a remainder of 372.
Record the quotient 1 as the next digit in the result. 
Result so far: 941.0
Subtracting 857 from 1229 leaves us with 372.
Fetch the next digit (6) from the dividend, attach it to 372 and continue: 3726 / 857

Moving on to step 7:
3726 divided by 857 is 4 with a remainder of 298.
Use 4 as the next digit of our solution. 
Result so far: 9414.0
If we take 3428 away from 3726, we end up with 298.
Grab the next digit (1) from the dividend, add it to 298, then carry on: 2981 / 857

Moving on to step 8:
857 can be fit into 2981 3 times, resulting in a remainder of 410.
Write down 3 as next digit of the result. 
Result so far: 94143.0
Deduct 2571 from 2981 and we're left with 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Advancing to step 9:
857 can be fit into 4100 4 times, resulting in a remainder of 672.
The number 4 becomes the next digit in our result. 
Result so far: 94143.4
Subtract 3428 from 4100 to get 672.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6720, and continue the process.

Going ahead to step 10:
When dividing 6720 by 857, we get 7 with a remainder of 721.
Record the quotient 7 as the next digit in the result. 
Result so far: 94143.47
If we subtract 5999 from 6720, we get 721.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7210, and continue the process.

Step 11:
857 can be fit into 7210 8 times, resulting in a remainder of 354.
Record the quotient 8 as the next digit in the result. 
Result so far: 94143.478
Deduct 6856 from 7210 and we're left with 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 12:
When dividing 3540 by 857, we get 4 with a remainder of 112.
Write down 4 as next digit of the result. 
Result so far: 94143.4784
Subtract 3428 from 3540 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 13:
The number 857 fits into 1120 1 times, leaving a remainder of 263.
Write down 1 as next digit of the result. 
Result so far: 94143.47841
Subtracting 857 from 1120 leaves us with 263.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2630, and continue the process.

Step 14:
857 can be fit into 2630 3 times, resulting in a remainder of 59.
Write down 3 as next digit of the result. 
Result so far: 94143.478413
If we take 2571 away from 2630, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 15:
590 divided by 857 is 0 with a remainder of 590.
Record the quotient 0 as the next digit in the result. 
Result so far: 94143.478413
If we subtract 0 from 590, we 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.

Going ahead to step 16:
When dividing 5900 by 857, we get 6 with a remainder of 758.
The number 6 becomes the next digit in our result. 
Result so far: 94143.47841306
Subtract 5142 from 5900 to get 758.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7580, and continue the process.

After the division, we end up with 94143.47841306 and a remainder of 7.58e-07.
