We look at the division of 864497 by 8 
We're looking to find how many times 8 goes into 864497.

Going ahead to step 1:
The number 8 fits into 8 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 8 from 8 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 8

Step 2:
8 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 6, we get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 8

Going ahead to step 3:
64 divided by 8 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Deduct 64 from 64 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 8

Let's proceed to step 4:
The number 8 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 1080.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 8

On to step 5:
If we divide 49 by 8, we get 6 and a remainder of 1.
The next digit of our result is 6. 
Result so far: 10806.0
Subtracting 48 from 49 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 8

Moving on to step 6:
8 goes into 17 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 108062.0
If we subtract 16 from 17, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
If we divide 10 by 8, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 108062.1
The remainder is 2 after subtracting 8 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
8 can be fit into 20 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 108062.12
If we subtract 16 from 20, we get 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 9:
8 can be fit into 40 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 108062.125
If we take 40 away from 40, we end up 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.

On to step 10:
0 divided by 8 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 108062.125
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.

Let's proceed to step 11:
8 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 108062.125
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.

After the division, we end up with 108062.125 and a remainder of 0.0.
