We're dividing 872579 by 8 
We want to divide 872579 by 8.

Let's proceed to step 1:
8 divided by 8 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 8

On to step 2:
If we divide 7 by 8, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 8

Let's proceed to step 3:
The number 8 fits into 72 9 times, leaving a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 109.0
The remainder is 0 after subtracting 72 from 72.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 8

Going ahead to step 4:
If we divide 5 by 8, we get 0 and a remainder of 5.
The next digit of our result is 0. 
Result so far: 1090.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 8

Step 5:
When dividing 57 by 8, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 10907.0
Subtracting 56 from 57 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 8

Moving on to step 6:
8 can be fit into 19 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 109072.0
The remainder is 3 after subtracting 16 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
The number 8 fits into 30 3 times, leaving a remainder of 6.
Record the quotient 3 as the next digit in the result. 
Result so far: 109072.3
Subtract 24 from 30 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
If we divide 60 by 8, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 109072.37
Subtracting 56 from 60 leaves us 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.

Going ahead to step 9:
The number 8 fits into 40 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 109072.375
Subtracting 40 from 40 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 109072.375
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
When dividing 0 by 8, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 109072.375
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 109072.375, with a leftover of 0.0.
