We're dividing 404383 by 43 
The aim is to understand the frequency of 43 in 404383.

Advancing to step 1:
The number 43 fits into 4 0 times, leaving 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.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 43

Let's proceed to step 2:
43 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (4) from the dividend, attach it to 40 and continue: 404 / 43

Let's proceed to step 3:
43 can be fit into 404 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 387 from 404, we get 17.
Take the next digit (3) from the dividend and append it to 17, then repeat: 173 / 43

Advancing to step 4:
43 goes into 173 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 94.0
If we subtract 172 from 173, we get 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 43

Step 5:
If we divide 18 by 43, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 940.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 43

Moving on to step 6:
The number 43 fits into 183 4 times, leaving a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 9404.0
Subtracting 172 from 183 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 43, we get 2 with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 9404.2
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
43 goes into 240 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 9404.25
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 9:
250 divided by 43 is 5 with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 9404.255
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Our division results in 9404.255 with a remaining 0.0035.
