Let's divide 72170278 by 879
Let's see how many times 879 fits into 72170278.

Let's proceed to step 1:
879 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 879

Going ahead to step 2:
If we divide 72 by 879, we get 0 and a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 72 and we're left with 72.
Grab the next digit (1) from the dividend, add it to 72, then carry on: 721 / 879

Moving on to step 3:
721 divided by 879 is 0 with a remainder of 721.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 721, we end up with 721.
Take the next digit (7) from the dividend and append it to 721, then repeat: 7217 / 879

Step 4:
When dividing 7217 by 879, we get 8 with a remainder of 185.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 7032 from 7217 to get 185.
Include the next digit (0) from the dividend after 185, then repeat: 1850 / 879

Going ahead to step 5:
The number 879 fits into 1850 2 times, leaving a remainder of 92.
Record the quotient 2 as the next digit in the result. 
Result so far: 82.0
Subtract 1758 from 1850 to get 92.
Take the next digit (2) from the dividend and append it to 92, then repeat: 922 / 879

Let's proceed to step 6:
879 goes into 922 1 times with a remainder of 43.
The number 1 becomes the next digit in our result. 
Result so far: 821.0
If we take 879 away from 922, we end up with 43.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 879

Moving on to step 7:
If we divide 437 by 879, we get 0 and a remainder of 437.
Put 0 as the next digit of the answer. 
Result so far: 8210.0
If we subtract 0 from 437, we get 437.
Take the next digit (8) from the dividend and append it to 437, then repeat: 4378 / 879

Advancing to step 8:
If we divide 4378 by 879, we get 4 and a remainder of 862.
Put 4 as the next digit of the answer. 
Result so far: 82104.0
Deduct 3516 from 4378 and we're left with 862.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8620, and continue the process.

Moving on to step 9:
If we divide 8620 by 879, we get 9 and a remainder of 709.
The next digit of our result is 9. 
Result so far: 82104.9
If we take 7911 away from 8620, we end up with 709.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7090, and continue the process.

Step 10:
If we divide 7090 by 879, we get 8 and a remainder of 58.
Use 8 as the next digit of our solution. 
Result so far: 82104.98
Subtracting 7032 from 7090 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Advancing to step 11:
When dividing 580 by 879, we get 0 with a remainder of 580.
Use 0 as the next digit of our solution. 
Result so far: 82104.98
Deduct 0 from 580 and we're left with 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Let's proceed to step 12:
When dividing 5800 by 879, we get 6 with a remainder of 526.
Write down 6 as next digit of the result. 
Result so far: 82104.9806
Deduct 5274 from 5800 and we're left with 526.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Advancing to step 13:
If we divide 5260 by 879, we get 5 and a remainder of 865.
The number 5 becomes the next digit in our result. 
Result so far: 82104.98065
If we subtract 4395 from 5260, we get 865.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8650, and continue the process.

Step 14:
If we divide 8650 by 879, we get 9 and a remainder of 739.
Write down 9 as next digit of the result. 
Result so far: 82104.980659
Deduct 7911 from 8650 and we're left with 739.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7390, and continue the process.

Advancing to step 15:
The number 879 fits into 7390 8 times, leaving a remainder of 358.
The next digit of our result is 8. 
Result so far: 82104.9806598
Subtract 7032 from 7390 to get 358.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3580, and continue the process.

Moving on to step 16:
The number 879 fits into 3580 4 times, leaving a remainder of 64.
The next digit of our result is 4. 
Result so far: 82104.98065984
Subtracting 3516 from 3580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 82104.98065984 with a remainder of 6.4e-08.
