Let's divide 15170101 by 879
We want to figure out the number of times 15170101 can be divided by 879.

Going ahead to step 1:
1 divided by 879 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 879

Step 2:
The number 879 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 879

Going ahead to step 3:
If we divide 151 by 879, we get 0 and a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 151 to get 151.
Grab the next digit (7) from the dividend, add it to 151, then carry on: 1517 / 879

Going ahead to step 4:
If we divide 1517 by 879, we get 1 and a remainder of 638.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 638 after subtracting 879 from 1517.
Bring next digit (0) of the dividend behind the 638 and repeat the process: 6380 / 879

Let's proceed to step 5:
When dividing 6380 by 879, we get 7 with a remainder of 227.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 227 after subtracting 6153 from 6380.
Append the next digit (1) from the dividend to 227 and continue with: 2271 / 879

Step 6:
879 can be fit into 2271 2 times, resulting in a remainder of 513.
Write down 2 as next digit of the result. 
Result so far: 172.0
The remainder is 513 after subtracting 1758 from 2271.
Include the next digit (0) from the dividend after 513, then repeat: 5130 / 879

Step 7:
879 goes into 5130 5 times with a remainder of 735.
Put 5 as the next digit of the answer. 
Result so far: 1725.0
If we subtract 4395 from 5130, we get 735.
Fetch the next digit (1) from the dividend, attach it to 735 and continue: 7351 / 879

On to step 8:
879 goes into 7351 8 times with a remainder of 319.
Put 8 as the next digit of the answer. 
Result so far: 17258.0
If we subtract 7032 from 7351, we get 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Step 9:
When dividing 3190 by 879, we get 3 with a remainder of 553.
Record the quotient 3 as the next digit in the result. 
Result so far: 17258.3
Subtracting 2637 from 3190 leaves us with 553.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5530, and continue the process.

Step 10:
The number 879 fits into 5530 6 times, leaving a remainder of 256.
Record the quotient 6 as the next digit in the result. 
Result so far: 17258.36
Deduct 5274 from 5530 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Advancing to step 11:
When dividing 2560 by 879, we get 2 with a remainder of 802.
Use 2 as the next digit of our solution. 
Result so far: 17258.362
Subtract 1758 from 2560 to get 802.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8020, and continue the process.

On to step 12:
879 can be fit into 8020 9 times, resulting in a remainder of 109.
The next digit of our result is 9. 
Result so far: 17258.3629
If we take 7911 away from 8020, we end up with 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1090, and continue the process.

Moving on to step 13:
879 can be fit into 1090 1 times, resulting in a remainder of 211.
Put 1 as the next digit of the answer. 
Result so far: 17258.36291
Subtracting 879 from 1090 leaves us with 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2110, and continue the process.

Step 14:
879 goes into 2110 2 times with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 17258.362912
The remainder is 352 after subtracting 1758 from 2110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
If we divide 3520 by 879, we get 4 and a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 17258.3629124
Deduct 3516 from 3520 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 16:
The number 879 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 17258.3629124
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final outcome is 17258.3629124, with a leftover of 4e-08.
