We look at the division of 12249679 by 43 
The aim is to understand the frequency of 43 in 12249679.

Let's proceed to step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 43

Let's proceed to step 2:
If we divide 12 by 43, we get 0 and a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 43

Step 3:
When dividing 122 by 43, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 86 from 122, we get 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 43

Moving on to step 4:
43 goes into 364 8 times with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 20 after subtracting 344 from 364.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

On to step 5:
43 can be fit into 209 4 times, resulting in a remainder of 37.
The next digit of our result is 4. 
Result so far: 284.0
Subtract 172 from 209 to get 37.
Grab the next digit (6) from the dividend, add it to 37, then carry on: 376 / 43

On to step 6:
If we divide 376 by 43, we get 8 and a remainder of 32.
The next digit of our result is 8. 
Result so far: 2848.0
Subtracting 344 from 376 leaves us with 32.
Bring next digit (7) of the dividend behind the 32 and repeat the process: 327 / 43

Let's proceed to step 7:
The number 43 fits into 327 7 times, leaving a remainder of 26.
The next digit of our result is 7. 
Result so far: 28487.0
If we take 301 away from 327, we end up with 26.
Append the next digit (9) from the dividend to 26 and continue with: 269 / 43

Step 8:
If we divide 269 by 43, we get 6 and a remainder of 11.
Put 6 as the next digit of the answer. 
Result so far: 284876.0
If we take 258 away from 269, we end up 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.

Advancing to step 9:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 284876.2
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.

Moving on to step 10:
When dividing 240 by 43, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 284876.25
Subtract 215 from 240 to 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.

Going ahead to step 11:
If we divide 250 by 43, we get 5 and a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 284876.255
Subtracting 215 from 250 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 284876.255, with a leftover of 0.0035.
