We're dividing 456724 by 9 
The aim is to understand the frequency of 9 in 456724.

Going ahead to step 1:
9 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 9

Let's proceed to step 2:
When dividing 45 by 9, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 45 from 45 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 9

Going ahead to step 3:
9 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 50.0
If we subtract 0 from 6, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 9

On to step 4:
The number 9 fits into 67 7 times, leaving a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 507.0
Deduct 63 from 67 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 9

Going ahead to step 5:
If we divide 42 by 9, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5074.0
Deduct 36 from 42 and we're left with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 9

Step 6:
The number 9 fits into 64 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 50747.0
Deduct 63 from 64 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
When dividing 10 by 9, we get 1 with a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 50747.1
Subtracting 9 from 10 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
If we divide 10 by 9, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 50747.11
The remainder is 1 after subtracting 9 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

After the division, we end up with 50747.11 and a remainder of 0.001.
