We look at the division of 576306 by 9 
The aim is to understand the frequency of 9 in 576306.

Step 1:
9 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 9

Moving on to step 2:
9 goes into 57 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
The remainder is 3 after subtracting 54 from 57.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 9

Going ahead to step 3:
When dividing 36 by 9, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we subtract 36 from 36, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 9

Moving on to step 4:
The number 9 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 640.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 9

Advancing to step 5:
The number 9 fits into 30 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 6403.0
Subtract 27 from 30 to get 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 9

Step 6:
When dividing 36 by 9, we get 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 64034.0
Deduct 36 from 36 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.

Moving on to step 7:
9 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64034.0
Subtract 0 from 0 to get 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 8:
0 divided by 9 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 64034.0
Subtract 0 from 0 to get 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 64034.0 and a remainder of 0.0.
