243404 divided by 9 
The aim is to understand the frequency of 9 in 243404.

Let's proceed to step 1:
9 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 9

Let's proceed to step 2:
When dividing 24 by 9, we get 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 18 from 24 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 9

Step 3:
When dividing 63 by 9, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
Subtract 63 from 63 to get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 9

Let's proceed to step 4:
If we divide 4 by 9, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 9

Moving on to step 5:
When dividing 40 by 9, we get 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 2704.0
If we subtract 36 from 40, we get 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 9

Step 6:
If we divide 44 by 9, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 27044.0
Subtracting 36 from 44 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
80 divided by 9 is 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 27044.8
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 8:
9 goes into 80 8 times with a remainder of 8.
The next digit of our result is 8. 
Result so far: 27044.88
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 27044.88 with a remainder of 0.008.
