We look at the division of 865664 by 9 
We want to divide 865664 by 9.

Step 1:
9 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 9

Let's proceed to step 2:
When dividing 86 by 9, we get 9 with a remainder of 5.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 81 away from 86, we end up with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 9

Step 3:
9 can be fit into 55 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 96.0
Deduct 54 from 55 and we're left with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 9

On to step 4:
9 can be fit into 16 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 961.0
Subtracting 9 from 16 leaves us with 7.
Take the next digit (6) from the dividend and append it to 7, then repeat: 76 / 9

Going ahead to step 5:
9 goes into 76 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9618.0
Deduct 72 from 76 and we're left with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 9

Moving on to step 6:
44 divided by 9 is 4 with a remainder of 8.
The next digit of our result is 4. 
Result so far: 96184.0
Subtract 36 from 44 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
The number 9 fits into 80 8 times, leaving a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 96184.8
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
When dividing 80 by 9, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 96184.88
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 96184.88, with a leftover of 0.008.
