If we divide 8 by 879, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 879

Moving on to step 2:
If we divide 86 by 879, we get 0 and a remainder of 86.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 86 leaves us with 86.
Grab the next digit (1) from the dividend, add it to 86, then carry on: 861 / 879

On to step 3:
879 can be fit into 861 0 times, resulting in a remainder of 861.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 861 to get 861.
Take the next digit (5) from the dividend and append it to 861, then repeat: 8615 / 879

Moving on to step 4:
When dividing 8615 by 879, we get 9 with a remainder of 704.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 7911 away from 8615, we end up with 704.
Append the next digit (8) from the dividend to 704 and continue with: 7048 / 879

On to step 5:
If we divide 7048 by 879, we get 8 and a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtract 7032 from 7048 to get 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 879

Going ahead to step 6:
The number 879 fits into 165 0 times, leaving a remainder of 165.
Use 0 as the next digit of our solution. 
Result so far: 980.0
If we subtract 0 from 165, we get 165.
Append the next digit (1) from the dividend to 165 and continue with: 1651 / 879

Moving on to step 7:
If we divide 1651 by 879, we get 1 and a remainder of 772.
Write down 1 as next digit of the result. 
Result so far: 9801.0
Subtract 879 from 1651 to get 772.
Take the next digit (0) from the dividend and append it to 772, then repeat: 7720 / 879

On to step 8:
If we divide 7720 by 879, we get 8 and a remainder of 688.
Record the quotient 8 as the next digit in the result. 
Result so far: 98018.0
Subtracting 7032 from 7720 leaves us with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Let's proceed to step 9:
6880 divided by 879 is 7 with a remainder of 727.
Put 7 as the next digit of the answer. 
Result so far: 98018.7
If we subtract 6153 from 6880, we get 727.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7270, and continue the process.

Advancing to step 10:
879 goes into 7270 8 times with a remainder of 238.
Use 8 as the next digit of our solution. 
Result so far: 98018.78
Subtracting 7032 from 7270 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Advancing to step 11:
2380 divided by 879 is 2 with a remainder of 622.
Put 2 as the next digit of the answer. 
Result so far: 98018.782
The remainder is 622 after subtracting 1758 from 2380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Let's proceed to step 12:
When dividing 6220 by 879, we get 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 98018.7827
Subtracting 6153 from 6220 leaves us with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 13:
879 can be fit into 670 0 times, resulting in a remainder of 670.
Record the quotient 0 as the next digit in the result. 
Result so far: 98018.7827
Deduct 0 from 670 and we're left with 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6700, and continue the process.

On to step 14:
When dividing 6700 by 879, we get 7 with a remainder of 547.
Write down 7 as next digit of the result. 
Result so far: 98018.782707
Subtracting 6153 from 6700 leaves us with 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Step 15:
879 can be fit into 5470 6 times, resulting in a remainder of 196.
The number 6 becomes the next digit in our result. 
Result so far: 98018.7827076
If we take 5274 away from 5470, we end up with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Moving on to step 16:
879 can be fit into 1960 2 times, resulting in a remainder of 202.
Record the quotient 2 as the next digit in the result. 
Result so far: 98018.78270762
If we take 1758 away from 1960, we end up with 202.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2020, and continue the process.

Our division results in 98018.78270762 with a remaining 2.02e-07.
