15951709 divided by 765 
We want to divide 15951709 by 765.

On to step 1:
When dividing 1 by 765, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 765

Going ahead to step 2:
765 can be fit into 15 0 times, resulting in a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 765

On to step 3:
765 goes into 159 0 times with a remainder of 159.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 159 and we're left with 159.
Grab the next digit (5) from the dividend, add it to 159, then carry on: 1595 / 765

On to step 4:
If we divide 1595 by 765, we get 2 and a remainder of 65.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1530 from 1595 and we're left with 65.
Include the next digit (1) from the dividend after 65, then repeat: 651 / 765

Advancing to step 5:
The number 765 fits into 651 0 times, leaving a remainder of 651.
The next digit of our result is 0. 
Result so far: 20.0
If we subtract 0 from 651, we get 651.
Take the next digit (7) from the dividend and append it to 651, then repeat: 6517 / 765

Let's proceed to step 6:
765 goes into 6517 8 times with a remainder of 397.
Put 8 as the next digit of the answer. 
Result so far: 208.0
Subtract 6120 from 6517 to get 397.
Append the next digit (0) from the dividend to 397 and continue with: 3970 / 765

On to step 7:
The number 765 fits into 3970 5 times, leaving a remainder of 145.
The next digit of our result is 5. 
Result so far: 2085.0
Subtract 3825 from 3970 to get 145.
Append the next digit (9) from the dividend to 145 and continue with: 1459 / 765

Moving on to step 8:
1459 divided by 765 is 1 with a remainder of 694.
The next digit of our result is 1. 
Result so far: 20851.0
The remainder is 694 after subtracting 765 from 1459.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6940, and continue the process.

On to step 9:
6940 divided by 765 is 9 with a remainder of 55.
The next digit of our result is 9. 
Result so far: 20851.9
Subtract 6885 from 6940 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 10:
550 divided by 765 is 0 with a remainder of 550.
The number 0 becomes the next digit in our result. 
Result so far: 20851.9
If we take 0 away from 550, we end up with 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5500, and continue the process.

On to step 11:
765 goes into 5500 7 times with a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 20851.907
The remainder is 145 after subtracting 5355 from 5500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Let's proceed to step 12:
765 can be fit into 1450 1 times, resulting in a remainder of 685.
Put 1 as the next digit of the answer. 
Result so far: 20851.9071
Subtracting 765 from 1450 leaves us with 685.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6850, and continue the process.

Advancing to step 13:
765 goes into 6850 8 times with a remainder of 730.
The number 8 becomes the next digit in our result. 
Result so far: 20851.90718
The remainder is 730 after subtracting 6120 from 6850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7300, and continue the process.

On to step 14:
If we divide 7300 by 765, we get 9 and a remainder of 415.
Use 9 as the next digit of our solution. 
Result so far: 20851.907189
Subtracting 6885 from 7300 leaves us with 415.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4150, and continue the process.

Let's proceed to step 15:
765 goes into 4150 5 times with a remainder of 325.
Write down 5 as next digit of the result. 
Result so far: 20851.9071895
If we subtract 3825 from 4150, we get 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 16:
3250 divided by 765 is 4 with a remainder of 190.
Record the quotient 4 as the next digit in the result. 
Result so far: 20851.90718954
Deduct 3060 from 3250 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

The final outcome is 20851.90718954, with a leftover of 1.9e-07.
