We're dividing 81507388 by 857 
Let's see how many times 857 fits into 81507388.

Moving on to step 1:
When dividing 8 by 857, we get 0 with 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.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 857

Going ahead to step 2:
The number 857 fits into 81 0 times, leaving a remainder of 81.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (5) from the dividend after 81, then repeat: 815 / 857

Let's proceed to step 3:
857 can be fit into 815 0 times, resulting in a remainder of 815.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 815 after subtracting 0 from 815.
Bring next digit (0) of the dividend behind the 815 and repeat the process: 8150 / 857

Moving on to step 4:
8150 divided by 857 is 9 with a remainder of 437.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7713 away from 8150, we end up with 437.
Fetch the next digit (7) from the dividend, attach it to 437 and continue: 4377 / 857

On to step 5:
857 can be fit into 4377 5 times, resulting in a remainder of 92.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 4285 from 4377 to get 92.
Append the next digit (3) from the dividend to 92 and continue with: 923 / 857

Going ahead to step 6:
If we divide 923 by 857, we get 1 and a remainder of 66.
Put 1 as the next digit of the answer. 
Result so far: 951.0
Subtract 857 from 923 to get 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 857

Advancing to step 7:
857 can be fit into 668 0 times, resulting in a remainder of 668.
Put 0 as the next digit of the answer. 
Result so far: 9510.0
If we take 0 away from 668, we end up with 668.
Grab the next digit (8) from the dividend, add it to 668, then carry on: 6688 / 857

Going ahead to step 8:
If we divide 6688 by 857, we get 7 and a remainder of 689.
Put 7 as the next digit of the answer. 
Result so far: 95107.0
Subtracting 5999 from 6688 leaves us with 689.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6890, and continue the process.

On to step 9:
6890 divided by 857 is 8 with a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 95107.8
The remainder is 34 after subtracting 6856 from 6890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 10:
When dividing 340 by 857, we get 0 with a remainder of 340.
The next digit of our result is 0. 
Result so far: 95107.8
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 11:
3400 divided by 857 is 3 with a remainder of 829.
The number 3 becomes the next digit in our result. 
Result so far: 95107.803
If we take 2571 away from 3400, we end up with 829.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8290, and continue the process.

Going ahead to step 12:
The number 857 fits into 8290 9 times, leaving a remainder of 577.
Put 9 as the next digit of the answer. 
Result so far: 95107.8039
If we take 7713 away from 8290, we end up with 577.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5770, and continue the process.

On to step 13:
When dividing 5770 by 857, we get 6 with a remainder of 628.
Use 6 as the next digit of our solution. 
Result so far: 95107.80396
Deduct 5142 from 5770 and we're left with 628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Let's proceed to step 14:
If we divide 6280 by 857, we get 7 and a remainder of 281.
The number 7 becomes the next digit in our result. 
Result so far: 95107.803967
Deduct 5999 from 6280 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Advancing to step 15:
If we divide 2810 by 857, we get 3 and a remainder of 239.
Use 3 as the next digit of our solution. 
Result so far: 95107.8039673
If we take 2571 away from 2810, we end up with 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Going ahead to step 16:
The number 857 fits into 2390 2 times, leaving a remainder of 676.
Put 2 as the next digit of the answer. 
Result so far: 95107.80396732
If we subtract 1714 from 2390, we get 676.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6760, and continue the process.

The final outcome is 95107.80396732, with a leftover of 6.76e-07.
