We look at the division of 69066191 by 857 
Let's see how many times 857 fits into 69066191.

Advancing to step 1:
When dividing 6 by 857, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 857

Step 2:
When dividing 69 by 857, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Bring next digit (0) of the dividend behind the 69 and repeat the process: 690 / 857

Advancing to step 3:
If we divide 690 by 857, we get 0 and a remainder of 690.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 690 after subtracting 0 from 690.
Append the next digit (6) from the dividend to 690 and continue with: 6906 / 857

Step 4:
6906 divided by 857 is 8 with a remainder of 50.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6856 away from 6906, we end up with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 857

Advancing to step 5:
If we divide 506 by 857, we get 0 and a remainder of 506.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we subtract 0 from 506, we get 506.
Fetch the next digit (1) from the dividend, attach it to 506 and continue: 5061 / 857

Advancing to step 6:
If we divide 5061 by 857, we get 5 and a remainder of 776.
Use 5 as the next digit of our solution. 
Result so far: 805.0
Subtract 4285 from 5061 to get 776.
Include the next digit (9) from the dividend after 776, then repeat: 7769 / 857

Advancing to step 7:
If we divide 7769 by 857, we get 9 and a remainder of 56.
Record the quotient 9 as the next digit in the result. 
Result so far: 8059.0
If we take 7713 away from 7769, we end up with 56.
Bring next digit (1) of the dividend behind the 56 and repeat the process: 561 / 857

Moving on to step 8:
857 can be fit into 561 0 times, resulting in a remainder of 561.
Write down 0 as next digit of the result. 
Result so far: 80590.0
If we subtract 0 from 561, we get 561.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5610, and continue the process.

Step 9:
857 can be fit into 5610 6 times, resulting in a remainder of 468.
Record the quotient 6 as the next digit in the result. 
Result so far: 80590.6
Deduct 5142 from 5610 and we're left with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Step 10:
4680 divided by 857 is 5 with a remainder of 395.
The number 5 becomes the next digit in our result. 
Result so far: 80590.65
Subtracting 4285 from 4680 leaves us with 395.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3950, and continue the process.

Moving on to step 11:
857 can be fit into 3950 4 times, resulting in a remainder of 522.
Record the quotient 4 as the next digit in the result. 
Result so far: 80590.654
Subtract 3428 from 3950 to get 522.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5220, and continue the process.

Going ahead to step 12:
If we divide 5220 by 857, we get 6 and a remainder of 78.
Use 6 as the next digit of our solution. 
Result so far: 80590.6546
Deduct 5142 from 5220 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

On to step 13:
780 divided by 857 is 0 with a remainder of 780.
Put 0 as the next digit of the answer. 
Result so far: 80590.6546
If we subtract 0 from 780, we get 780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7800, and continue the process.

Moving on to step 14:
7800 divided by 857 is 9 with a remainder of 87.
Use 9 as the next digit of our solution. 
Result so far: 80590.654609
If we subtract 7713 from 7800, we get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 15:
The number 857 fits into 870 1 times, leaving a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 80590.6546091
If we subtract 857 from 870, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 16:
857 goes into 130 0 times with a remainder of 130.
The number 0 becomes the next digit in our result. 
Result so far: 80590.6546091
The remainder is 130 after subtracting 0 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

In conclusion, the division gives 80590.6546091 with a balance of 1.3e-07.
