We're dividing 389432 by 9 
The aim is to understand the frequency of 9 in 389432.

Let's proceed to step 1:
9 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 9

On to step 2:
38 divided by 9 is 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 36 from 38 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 9

Moving on to step 3:
When dividing 29 by 9, we get 3 with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
Subtract 27 from 29 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 9

Moving on to step 4:
If we divide 24 by 9, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 432.0
Subtracting 18 from 24 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 9

Advancing to step 5:
9 goes into 63 7 times with a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 4327.0
Subtract 63 from 63 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 9

On to step 6:
The number 9 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 43270.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 9 fits into 20 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 43270.2
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
9 can be fit into 20 2 times, resulting in a remainder of 2.
The next digit of our result is 2. 
Result so far: 43270.22
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 43270.22 with a remainder of 0.002.
