We're dividing 430855 by 9 
The aim is to understand the frequency of 9 in 430855.

Advancing to step 1:
4 divided by 9 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 9

On to step 2:
When dividing 43 by 9, we get 4 with a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 36 from 43 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 9

Let's proceed to step 3:
If we divide 70 by 9, we get 7 and a remainder of 7.
The number 7 becomes the next digit in our result. 
Result so far: 47.0
If we subtract 63 from 70, we get 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 9

Advancing to step 4:
9 can be fit into 78 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 478.0
If we subtract 72 from 78, we get 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 9

Advancing to step 5:
9 goes into 65 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 4787.0
If we subtract 63 from 65, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 9

Let's proceed to step 6:
The number 9 fits into 25 2 times, leaving a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 47872.0
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:
70 divided by 9 is 7 with a remainder of 7.
The next digit of our result is 7. 
Result so far: 47872.7
Deduct 63 from 70 and we're left 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.

Advancing to step 8:
70 divided by 9 is 7 with a remainder of 7.
Record the quotient 7 as the next digit in the result. 
Result so far: 47872.77
Subtracting 63 from 70 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.

Our division results in 47872.77 with a remaining 0.007.
