Let's divide 43472 by 9
The aim is to understand the frequency of 9 in 43472.

Moving on to step 1:
When dividing 4 by 9, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 9

Advancing to step 2:
The number 9 fits into 43 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 36 from 43 leaves us with 7.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 9

Step 3:
The number 9 fits into 74 8 times, leaving a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 72 from 74 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 9

Step 4:
27 divided by 9 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 483.0
The remainder is 0 after subtracting 27 from 27.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 9

On to step 5:
2 divided by 9 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 4830.0
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.

On to step 6:
9 goes into 20 2 times with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 4830.2
Deduct 18 from 20 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.

Moving on to step 7:
When dividing 20 by 9, we get 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 4830.22
If we subtract 18 from 20, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

After the division, we end up with 4830.22 and a remainder of 0.002.
