488309 divided by 9 
The aim is to understand the frequency of 9 in 488309.

Let's proceed to step 1:
The number 9 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 9

Let's proceed to step 2:
The number 9 fits into 48 5 times, leaving a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 45 away from 48, we end up with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 9

Going ahead to step 3:
38 divided by 9 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 54.0
Subtract 36 from 38 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 9

Advancing to step 4:
23 divided by 9 is 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 542.0
Subtract 18 from 23 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 9

On to step 5:
The number 9 fits into 50 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 5425.0
Deduct 45 from 50 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 9

On to step 6:
The number 9 fits into 59 6 times, leaving a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 54256.0
If we subtract 54 from 59, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 54256.5
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
50 divided by 9 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 54256.55
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 54256.55 with a balance of 0.005.
