866474 divided by 8 
Our goal is to divide 866474 by 8.

Going ahead to step 1:
8 goes into 8 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 8 from 8.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 8

Let's proceed to step 2:
6 divided by 8 is 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 8

Let's proceed to step 3:
When dividing 66 by 8, we get 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 108.0
The remainder is 2 after subtracting 64 from 66.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 8

Advancing to step 4:
8 goes into 24 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 1083.0
The remainder is 0 after subtracting 24 from 24.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 8

On to step 5:
The number 8 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 10830.0
Subtract 0 from 7 to get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 8

Step 6:
The number 8 fits into 74 9 times, leaving a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 108309.0
If we subtract 72 from 74, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
8 goes into 20 2 times with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 108309.2
Subtracting 16 from 20 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.

Let's proceed to step 8:
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: 108309.25
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.

Moving on to step 9:
When dividing 0 by 8, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 108309.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
When dividing 0 by 8, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 108309.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 108309.25 with a remaining 0.0.
