We look at the division of 87690340 by 857 
We want to figure out the number of times 87690340 can be divided by 857.

On to step 1:
857 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 857

On to step 2:
The number 857 fits into 87 0 times, leaving a remainder of 87.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 87 to get 87.
Append the next digit (6) from the dividend to 87 and continue with: 876 / 857

Step 3:
When dividing 876 by 857, we get 1 with a remainder of 19.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 19 after subtracting 857 from 876.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 857

On to step 4:
857 can be fit into 199 0 times, resulting in a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 199 leaves us with 199.
Bring next digit (0) of the dividend behind the 199 and repeat the process: 1990 / 857

Let's proceed to step 5:
If we divide 1990 by 857, we get 2 and a remainder of 276.
Put 2 as the next digit of the answer. 
Result so far: 102.0
If we take 1714 away from 1990, we end up with 276.
Grab the next digit (3) from the dividend, add it to 276, then carry on: 2763 / 857

Advancing to step 6:
857 can be fit into 2763 3 times, resulting in a remainder of 192.
Write down 3 as next digit of the result. 
Result so far: 1023.0
Subtracting 2571 from 2763 leaves us with 192.
Grab the next digit (4) from the dividend, add it to 192, then carry on: 1924 / 857

Advancing to step 7:
857 can be fit into 1924 2 times, resulting in a remainder of 210.
The next digit of our result is 2. 
Result so far: 10232.0
Subtracting 1714 from 1924 leaves us with 210.
Bring next digit (0) of the dividend behind the 210 and repeat the process: 2100 / 857

Going ahead to step 8:
The number 857 fits into 2100 2 times, leaving a remainder of 386.
Use 2 as the next digit of our solution. 
Result so far: 102322.0
Subtracting 1714 from 2100 leaves us with 386.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3860, and continue the process.

Going ahead to step 9:
857 can be fit into 3860 4 times, resulting in a remainder of 432.
Write down 4 as next digit of the result. 
Result so far: 102322.4
The remainder is 432 after subtracting 3428 from 3860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

On to step 10:
The number 857 fits into 4320 5 times, leaving a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 102322.45
If we subtract 4285 from 4320, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 11:
If we divide 350 by 857, we get 0 and a remainder of 350.
Use 0 as the next digit of our solution. 
Result so far: 102322.45
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 12:
3500 divided by 857 is 4 with a remainder of 72.
Put 4 as the next digit of the answer. 
Result so far: 102322.4504
If we take 3428 away from 3500, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 13:
857 can be fit into 720 0 times, resulting in a remainder of 720.
The number 0 becomes the next digit in our result. 
Result so far: 102322.4504
The remainder is 720 after subtracting 0 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Step 14:
7200 divided by 857 is 8 with a remainder of 344.
The next digit of our result is 8. 
Result so far: 102322.450408
Subtracting 6856 from 7200 leaves us with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 15:
If we divide 3440 by 857, we get 4 and a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 102322.4504084
If we subtract 3428 from 3440, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 16:
857 goes into 120 0 times with a remainder of 120.
Use 0 as the next digit of our solution. 
Result so far: 102322.4504084
Deduct 0 from 120 and we're left with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

In conclusion, the division gives 102322.4504084 with a balance of 1.2e-07.
