Let's divide 456864 by 9
We're looking to find how many times 9 goes into 456864.

Going ahead to step 1:
The number 9 fits into 4 0 times, leaving a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 9

Moving on to step 2:
When dividing 45 by 9, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 0 after subtracting 45 from 45.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 9

Step 3:
9 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 50.0
Subtracting 0 from 6 leaves us with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 9

Going ahead to step 4:
68 divided by 9 is 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 507.0
If we subtract 63 from 68, we get 5.
Fetch the next digit (6) from the dividend, attach it to 5 and continue: 56 / 9

Moving on to step 5:
If we divide 56 by 9, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 5076.0
If we subtract 54 from 56, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 9

Going ahead to step 6:
9 can be fit into 24 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 50762.0
Subtract 18 from 24 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.

Let's proceed to step 7:
The number 9 fits into 60 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 50762.6
Subtract 54 from 60 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.

Advancing to step 8:
When dividing 60 by 9, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 50762.66
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 50762.66 with a remainder of 0.006.
