79842557 divided by 878 
We want to divide 79842557 by 878.

On to step 1:
The number 878 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 878

Moving on to step 2:
The number 878 fits into 79 0 times, leaving a remainder of 79.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 79 to get 79.
Fetch the next digit (8) from the dividend, attach it to 79 and continue: 798 / 878

Going ahead to step 3:
878 goes into 798 0 times with a remainder of 798.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 798 to get 798.
Fetch the next digit (4) from the dividend, attach it to 798 and continue: 7984 / 878

Going ahead to step 4:
7984 divided by 878 is 9 with a remainder of 82.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 7902 away from 7984, we end up with 82.
Grab the next digit (2) from the dividend, add it to 82, then carry on: 822 / 878

Moving on to step 5:
The number 878 fits into 822 0 times, leaving a remainder of 822.
The next digit of our result is 0. 
Result so far: 90.0
Subtract 0 from 822 to get 822.
Take the next digit (5) from the dividend and append it to 822, then repeat: 8225 / 878

On to step 6:
When dividing 8225 by 878, we get 9 with a remainder of 323.
The next digit of our result is 9. 
Result so far: 909.0
If we take 7902 away from 8225, we end up with 323.
Grab the next digit (5) from the dividend, add it to 323, then carry on: 3235 / 878

On to step 7:
3235 divided by 878 is 3 with a remainder of 601.
Put 3 as the next digit of the answer. 
Result so far: 9093.0
Subtracting 2634 from 3235 leaves us with 601.
Bring next digit (7) of the dividend behind the 601 and repeat the process: 6017 / 878

Step 8:
When dividing 6017 by 878, we get 6 with a remainder of 749.
The number 6 becomes the next digit in our result. 
Result so far: 90936.0
The remainder is 749 after subtracting 5268 from 6017.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7490, and continue the process.

On to step 9:
7490 divided by 878 is 8 with a remainder of 466.
The next digit of our result is 8. 
Result so far: 90936.8
Subtracting 7024 from 7490 leaves us with 466.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4660, and continue the process.

Going ahead to step 10:
If we divide 4660 by 878, we get 5 and a remainder of 270.
The number 5 becomes the next digit in our result. 
Result so far: 90936.85
The remainder is 270 after subtracting 4390 from 4660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Step 11:
2700 divided by 878 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 90936.853
The remainder is 66 after subtracting 2634 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
When dividing 660 by 878, we get 0 with a remainder of 660.
Use 0 as the next digit of our solution. 
Result so far: 90936.853
Subtracting 0 from 660 leaves us with 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6600, and continue the process.

Let's proceed to step 13:
6600 divided by 878 is 7 with a remainder of 454.
Write down 7 as next digit of the result. 
Result so far: 90936.85307
Deduct 6146 from 6600 and we're left with 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

Moving on to step 14:
4540 divided by 878 is 5 with a remainder of 150.
Use 5 as the next digit of our solution. 
Result so far: 90936.853075
Subtract 4390 from 4540 to get 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Going ahead to step 15:
1500 divided by 878 is 1 with a remainder of 622.
Use 1 as the next digit of our solution. 
Result so far: 90936.8530751
If we take 878 away from 1500, we end up with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Advancing to step 16:
If we divide 6220 by 878, we get 7 and a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 90936.85307517
Subtract 6146 from 6220 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Our division results in 90936.85307517 with a remaining 7.4e-08.
