We look at the division of 729635 by 9 
The aim is to understand the frequency of 9 in 729635.

Moving on to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 9

Advancing to step 2:
When dividing 72 by 9, we get 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 72 from 72 leaves us with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 9

Let's proceed to step 3:
The number 9 fits into 9 1 times, leaving a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 9 away from 9, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 9

Moving on to step 4:
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: 810.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 9

Moving on to step 5:
When dividing 63 by 9, we get 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 8107.0
The remainder is 0 after subtracting 63 from 63.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 9

Advancing to step 6:
If we divide 5 by 9, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 81070.0
If we take 0 away from 5, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 7:
If we divide 50 by 9, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 81070.5
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.

Moving on to step 8:
9 can be fit into 50 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 81070.55
Deduct 45 from 50 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 81070.55 and a remainder of 0.005.
