We look at the division of 99086646 by 708 
We want to divide 99086646 by 708.

Step 1:
The number 708 fits into 9 0 times, leaving a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 708

Step 2:
The number 708 fits into 99 0 times, leaving a remainder of 99.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 99 after subtracting 0 from 99.
Take the next digit (0) from the dividend and append it to 99, then repeat: 990 / 708

Advancing to step 3:
708 can be fit into 990 1 times, resulting in a remainder of 282.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 708 from 990 and we're left with 282.
Bring next digit (8) of the dividend behind the 282 and repeat the process: 2828 / 708

Let's proceed to step 4:
If we divide 2828 by 708, we get 3 and a remainder of 704.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 2124 from 2828 leaves us with 704.
Append the next digit (6) from the dividend to 704 and continue with: 7046 / 708

Advancing to step 5:
708 goes into 7046 9 times with a remainder of 674.
The number 9 becomes the next digit in our result. 
Result so far: 139.0
Subtracting 6372 from 7046 leaves us with 674.
Bring next digit (6) of the dividend behind the 674 and repeat the process: 6746 / 708

Step 6:
When dividing 6746 by 708, we get 9 with a remainder of 374.
Put 9 as the next digit of the answer. 
Result so far: 1399.0
The remainder is 374 after subtracting 6372 from 6746.
Take the next digit (4) from the dividend and append it to 374, then repeat: 3744 / 708

Going ahead to step 7:
3744 divided by 708 is 5 with a remainder of 204.
Record the quotient 5 as the next digit in the result. 
Result so far: 13995.0
Deduct 3540 from 3744 and we're left with 204.
Append the next digit (6) from the dividend to 204 and continue with: 2046 / 708

Moving on to step 8:
The number 708 fits into 2046 2 times, leaving a remainder of 630.
Record the quotient 2 as the next digit in the result. 
Result so far: 139952.0
If we subtract 1416 from 2046, we get 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 9:
708 goes into 6300 8 times with a remainder of 636.
The number 8 becomes the next digit in our result. 
Result so far: 139952.8
Subtract 5664 from 6300 to get 636.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6360, and continue the process.

Going ahead to step 10:
When dividing 6360 by 708, we get 8 with a remainder of 696.
The next digit of our result is 8. 
Result so far: 139952.88
The remainder is 696 after subtracting 5664 from 6360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6960, and continue the process.

The final result is 139952.88 with a remainder of 0.696.
