Let's divide 56688660 by 857
We're looking to find how many times 857 goes into 56688660.

Advancing to step 1:
When dividing 5 by 857, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 857

Let's proceed to step 2:
56 divided by 857 is 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 56 leaves us with 56.
Include the next digit (6) from the dividend after 56, then repeat: 566 / 857

Going ahead to step 3:
566 divided by 857 is 0 with a remainder of 566.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 566, we end up with 566.
Include the next digit (8) from the dividend after 566, then repeat: 5668 / 857

Going ahead to step 4:
When dividing 5668 by 857, we get 6 with a remainder of 526.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 5142 from 5668 and we're left with 526.
Bring next digit (8) of the dividend behind the 526 and repeat the process: 5268 / 857

On to step 5:
857 can be fit into 5268 6 times, resulting in a remainder of 126.
Put 6 as the next digit of the answer. 
Result so far: 66.0
Subtracting 5142 from 5268 leaves us with 126.
Fetch the next digit (6) from the dividend, attach it to 126 and continue: 1266 / 857

Advancing to step 6:
When dividing 1266 by 857, we get 1 with a remainder of 409.
Put 1 as the next digit of the answer. 
Result so far: 661.0
Subtract 857 from 1266 to get 409.
Fetch the next digit (6) from the dividend, attach it to 409 and continue: 4096 / 857

Let's proceed to step 7:
If we divide 4096 by 857, we get 4 and a remainder of 668.
Use 4 as the next digit of our solution. 
Result so far: 6614.0
The remainder is 668 after subtracting 3428 from 4096.
Fetch the next digit (0) from the dividend, attach it to 668 and continue: 6680 / 857

Step 8:
857 can be fit into 6680 7 times, resulting in a remainder of 681.
Use 7 as the next digit of our solution. 
Result so far: 66147.0
Deduct 5999 from 6680 and we're left with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Let's proceed to step 9:
The number 857 fits into 6810 7 times, leaving a remainder of 811.
Write down 7 as next digit of the result. 
Result so far: 66147.7
Subtracting 5999 from 6810 leaves us with 811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8110, and continue the process.

Step 10:
If we divide 8110 by 857, we get 9 and a remainder of 397.
Use 9 as the next digit of our solution. 
Result so far: 66147.79
Subtract 7713 from 8110 to get 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Moving on to step 11:
857 goes into 3970 4 times with a remainder of 542.
Record the quotient 4 as the next digit in the result. 
Result so far: 66147.794
Subtract 3428 from 3970 to get 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

Advancing to step 12:
The number 857 fits into 5420 6 times, leaving a remainder of 278.
Use 6 as the next digit of our solution. 
Result so far: 66147.7946
Subtract 5142 from 5420 to get 278.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2780, and continue the process.

Step 13:
2780 divided by 857 is 3 with a remainder of 209.
Write down 3 as next digit of the result. 
Result so far: 66147.79463
The remainder is 209 after subtracting 2571 from 2780.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Advancing to step 14:
If we divide 2090 by 857, we get 2 and a remainder of 376.
The number 2 becomes the next digit in our result. 
Result so far: 66147.794632
If we subtract 1714 from 2090, we get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

On to step 15:
If we divide 3760 by 857, we get 4 and a remainder of 332.
Use 4 as the next digit of our solution. 
Result so far: 66147.7946324
If we subtract 3428 from 3760, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 16:
857 can be fit into 3320 3 times, resulting in a remainder of 749.
The next digit of our result is 3. 
Result so far: 66147.79463243
Deduct 2571 from 3320 and we're left with 749.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

The final result is 66147.79463243 with a remainder of 7.49e-07.
