We look at the division of 66828967 by 857 
We want to divide 66828967 by 857.

On to step 1:
6 divided by 857 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 857

Step 2:
If we divide 66 by 857, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 66 leaves us with 66.
Include the next digit (8) from the dividend after 66, then repeat: 668 / 857

Going ahead to step 3:
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: 0.0
If we take 0 away from 668, we end up with 668.
Include the next digit (2) from the dividend after 668, then repeat: 6682 / 857

Let's proceed to step 4:
6682 divided by 857 is 7 with a remainder of 683.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtract 5999 from 6682 to get 683.
Grab the next digit (8) from the dividend, add it to 683, then carry on: 6838 / 857

Advancing to step 5:
857 can be fit into 6838 7 times, resulting in a remainder of 839.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtracting 5999 from 6838 leaves us with 839.
Fetch the next digit (9) from the dividend, attach it to 839 and continue: 8399 / 857

Let's proceed to step 6:
The number 857 fits into 8399 9 times, leaving a remainder of 686.
The next digit of our result is 9. 
Result so far: 779.0
The remainder is 686 after subtracting 7713 from 8399.
Append the next digit (6) from the dividend to 686 and continue with: 6866 / 857

On to step 7:
The number 857 fits into 6866 8 times, leaving a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 7798.0
Subtracting 6856 from 6866 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 857

Going ahead to step 8:
The number 857 fits into 107 0 times, leaving a remainder of 107.
Write down 0 as next digit of the result. 
Result so far: 77980.0
If we take 0 away from 107, we end up with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

On to step 9:
857 can be fit into 1070 1 times, resulting in a remainder of 213.
The next digit of our result is 1. 
Result so far: 77980.1
If we take 857 away from 1070, we end up with 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Advancing to step 10:
The number 857 fits into 2130 2 times, leaving a remainder of 416.
Write down 2 as next digit of the result. 
Result so far: 77980.12
If we subtract 1714 from 2130, we get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Advancing to step 11:
The number 857 fits into 4160 4 times, leaving a remainder of 732.
Write down 4 as next digit of the result. 
Result so far: 77980.124
Deduct 3428 from 4160 and we're left with 732.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7320, and continue the process.

On to step 12:
The number 857 fits into 7320 8 times, leaving a remainder of 464.
The next digit of our result is 8. 
Result so far: 77980.1248
If we subtract 6856 from 7320, we get 464.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4640, and continue the process.

Moving on to step 13:
4640 divided by 857 is 5 with a remainder of 355.
Use 5 as the next digit of our solution. 
Result so far: 77980.12485
Subtract 4285 from 4640 to get 355.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3550, and continue the process.

Moving on to step 14:
857 goes into 3550 4 times with a remainder of 122.
Use 4 as the next digit of our solution. 
Result so far: 77980.124854
If we subtract 3428 from 3550, we get 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 15:
If we divide 1220 by 857, we get 1 and a remainder of 363.
The next digit of our result is 1. 
Result so far: 77980.1248541
Subtracting 857 from 1220 leaves us with 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3630, and continue the process.

Going ahead to step 16:
If we divide 3630 by 857, we get 4 and a remainder of 202.
The number 4 becomes the next digit in our result. 
Result so far: 77980.12485414
The remainder is 202 after subtracting 3428 from 3630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

The final outcome is 77980.12485414, with a leftover of 2.02e-07.
