15717170 divided by 879 
Let's see how many times 879 fits into 15717170.

Going ahead to step 1:
When dividing 1 by 879, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 879

On to step 2:
15 divided by 879 is 0 with a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 879

Step 3:
When dividing 157 by 879, we get 0 with a remainder of 157.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 157, we end up with 157.
Grab the next digit (1) from the dividend, add it to 157, then carry on: 1571 / 879

Step 4:
When dividing 1571 by 879, we get 1 with a remainder of 692.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 879 away from 1571, we end up with 692.
Fetch the next digit (7) from the dividend, attach it to 692 and continue: 6927 / 879

Going ahead to step 5:
When dividing 6927 by 879, we get 7 with a remainder of 774.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 774 after subtracting 6153 from 6927.
Grab the next digit (1) from the dividend, add it to 774, then carry on: 7741 / 879

Moving on to step 6:
7741 divided by 879 is 8 with a remainder of 709.
Record the quotient 8 as the next digit in the result. 
Result so far: 178.0
Deduct 7032 from 7741 and we're left with 709.
Take the next digit (7) from the dividend and append it to 709, then repeat: 7097 / 879

Advancing to step 7:
If we divide 7097 by 879, we get 8 and a remainder of 65.
The next digit of our result is 8. 
Result so far: 1788.0
If we subtract 7032 from 7097, we get 65.
Append the next digit (0) from the dividend to 65 and continue with: 650 / 879

Let's proceed to step 8:
879 can be fit into 650 0 times, resulting in a remainder of 650.
Record the quotient 0 as the next digit in the result. 
Result so far: 17880.0
Subtracting 0 from 650 leaves us with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

Going ahead to step 9:
If we divide 6500 by 879, we get 7 and a remainder of 347.
The number 7 becomes the next digit in our result. 
Result so far: 17880.7
Deduct 6153 from 6500 and we're left with 347.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3470, and continue the process.

On to step 10:
879 goes into 3470 3 times with a remainder of 833.
The next digit of our result is 3. 
Result so far: 17880.73
The remainder is 833 after subtracting 2637 from 3470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8330, and continue the process.

Going ahead to step 11:
If we divide 8330 by 879, we get 9 and a remainder of 419.
The next digit of our result is 9. 
Result so far: 17880.739
If we subtract 7911 from 8330, we get 419.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4190, and continue the process.

Let's proceed to step 12:
4190 divided by 879 is 4 with a remainder of 674.
Put 4 as the next digit of the answer. 
Result so far: 17880.7394
Subtract 3516 from 4190 to get 674.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6740, and continue the process.

On to step 13:
If we divide 6740 by 879, we get 7 and a remainder of 587.
Record the quotient 7 as the next digit in the result. 
Result so far: 17880.73947
Subtract 6153 from 6740 to get 587.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5870, and continue the process.

Going ahead to step 14:
When dividing 5870 by 879, we get 6 with a remainder of 596.
The number 6 becomes the next digit in our result. 
Result so far: 17880.739476
If we take 5274 away from 5870, we end up with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 15:
When dividing 5960 by 879, we get 6 with a remainder of 686.
The number 6 becomes the next digit in our result. 
Result so far: 17880.7394766
Subtracting 5274 from 5960 leaves us with 686.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6860, and continue the process.

The final result is 17880.7394766 with a remainder of 6.86e-06.
