We divide 432859 by 9
The aim is to understand the frequency of 9 in 432859.

Moving on to step 1:
9 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 9

On to step 2:
43 divided by 9 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 36 from 43 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 9

Let's proceed to step 3:
9 can be fit into 72 8 times, resulting in a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 48.0
The remainder is 0 after subtracting 72 from 72.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 9

Let's proceed to step 4:
If we divide 8 by 9, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 9

On to step 5:
9 goes into 85 9 times with a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 4809.0
If we subtract 81 from 85, we get 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 9

On to step 6:
9 goes into 49 5 times with a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 48095.0
Subtracting 45 from 49 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
9 goes into 40 4 times with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 48095.4
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
40 divided by 9 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 48095.44
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

After the division, we end up with 48095.44 and a remainder of 0.004.
