We look at the division of 622735 by 9 
The aim is to understand the frequency of 9 in 622735.

Let's proceed to step 1:
9 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 9

Moving on to step 2:
62 divided by 9 is 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 8 after subtracting 54 from 62.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 9

Advancing to step 3:
9 goes into 82 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 81 from 82 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 9

Let's proceed to step 4:
17 divided by 9 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 691.0
Deduct 9 from 17 and we're left with 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 9

Step 5:
9 goes into 83 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 6919.0
The remainder is 2 after subtracting 81 from 83.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 9

Advancing to step 6:
If we divide 25 by 9, we get 2 and a remainder of 7.
The number 2 becomes the next digit in our result. 
Result so far: 69192.0
The remainder is 7 after subtracting 18 from 25.
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 7:
When dividing 70 by 9, we get 7 with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 69192.7
If we subtract 63 from 70, we 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.

Let's proceed to step 8:
9 can be fit into 70 7 times, resulting in a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 69192.77
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 69192.77 and a remainder of 0.007.
