648324 divided by 9 
The aim is to understand the frequency of 9 in 648324.

Let's proceed to step 1:
When dividing 6 by 9, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 9

Going ahead to step 2:
If we divide 64 by 9, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 63 away from 64, we end up with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 9

Let's proceed to step 3:
18 divided by 9 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 72.0
Deduct 18 from 18 and we're left with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 9

Going ahead to step 4:
9 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 720.0
Subtract 0 from 3 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 9

On to step 5:
The number 9 fits into 32 3 times, leaving a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 7203.0
Deduct 27 from 32 and we're left with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 9

Let's proceed to step 6:
9 goes into 54 6 times with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 72036.0
If we take 54 away from 54, 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.

Advancing to step 7:
9 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72036.0
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.

Advancing to step 8:
If we divide 0 by 9, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 72036.0
Deduct 0 from 0 and we're left 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.

In conclusion, the division gives 72036.0 with a balance of 0.0.
