We look at the division of 849039 by 43 
The aim is to understand the frequency of 43 in 849039.

Advancing to step 1:
When dividing 8 by 43, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 43

Going ahead to step 2:
43 can be fit into 84 1 times, resulting in a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 84 leaves us with 41.
Include the next digit (9) from the dividend after 41, then repeat: 419 / 43

On to step 3:
43 can be fit into 419 9 times, resulting in a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Subtracting 387 from 419 leaves us with 32.
Bring next digit (0) of the dividend behind the 32 and repeat the process: 320 / 43

Let's proceed to step 4:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 197.0
If we subtract 301 from 320, we get 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 43

Moving on to step 5:
43 goes into 193 4 times with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 1974.0
Subtracting 172 from 193 leaves us with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 43

Moving on to step 6:
The number 43 fits into 219 5 times, leaving a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 19745.0
If we take 215 away from 219, we end up 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.

Step 7:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 19745.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 8:
If we divide 400 by 43, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 19745.09
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
130 divided by 43 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 19745.093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
43 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 19745.093
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 11:
100 divided by 43 is 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 19745.09302
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 12:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 19745.093023
Subtracting 129 from 140 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.

Step 13:
43 goes into 110 2 times with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 19745.0930232
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
The number 43 fits into 240 5 times, leaving a remainder of 25.
The next digit of our result is 5. 
Result so far: 19745.09302325
If we take 215 away from 240, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 19745.09302325 with a balance of 2.5e-08.
