Let's divide 308545 by 9
The aim is to understand the frequency of 9 in 308545.

Going ahead to step 1:
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: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 9

Step 2:
30 divided by 9 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 27 from 30, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 9

Going ahead to step 3:
9 can be fit into 38 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 36 from 38, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 9

Let's proceed to step 4:
If we divide 25 by 9, we get 2 and a remainder of 7.
Record the quotient 2 as the next digit in the result. 
Result so far: 342.0
Subtracting 18 from 25 leaves us with 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 9

Let's proceed to step 5:
74 divided by 9 is 8 with a remainder of 2.
The next digit of our result is 8. 
Result so far: 3428.0
Subtract 72 from 74 to get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 9

Step 6:
9 can be fit into 25 2 times, resulting in a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 34282.0
Subtracting 18 from 25 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 9, we get 7 and a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 34282.7
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 9 is 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 34282.77
Subtract 63 from 70 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

The final result is 34282.77 with a remainder of 0.007.
