We look at the division of 752403 by 43 
The aim is to understand the frequency of 43 in 752403.

Let's proceed to step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (5) from the dividend and append it to 7, then repeat: 75 / 43

Moving on to step 2:
The number 43 fits into 75 1 times, leaving a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 43 away from 75, we end up with 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 43

Going ahead to step 3:
When dividing 322 by 43, we get 7 with a remainder of 21.
Write down 7 as next digit of the result. 
Result so far: 17.0
If we take 301 away from 322, we end up with 21.
Include the next digit (4) from the dividend after 21, then repeat: 214 / 43

Advancing to step 4:
When dividing 214 by 43, we get 4 with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
If we subtract 172 from 214, we get 42.
Take the next digit (0) from the dividend and append it to 42, then repeat: 420 / 43

Let's proceed to step 5:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 1749.0
Subtracting 387 from 420 leaves us with 33.
Take the next digit (3) from the dividend and append it to 33, then repeat: 333 / 43

On to step 6:
The number 43 fits into 333 7 times, leaving a remainder of 32.
Record the quotient 7 as the next digit in the result. 
Result so far: 17497.0
The remainder is 32 after subtracting 301 from 333.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 7:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 17497.7
If we take 301 away from 320, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 17497.74
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
43 can be fit into 180 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 17497.744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 17497.744 with a balance of 0.0008.
