We look at the division of 17565072 by 43 
The aim is to understand the frequency of 43 in 17565072.

Going ahead to step 1:
The number 43 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 43

On to step 2:
When dividing 17 by 43, we get 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 17, we end up with 17.
Fetch the next digit (5) from the dividend, attach it to 17 and continue: 175 / 43

Moving on to step 3:
The number 43 fits into 175 4 times, leaving a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 172 from 175, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 43

Let's proceed to step 4:
43 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 40.0
Deduct 0 from 36 and we're left with 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 43

Step 5:
When dividing 365 by 43, we get 8 with a remainder of 21.
The next digit of our result is 8. 
Result so far: 408.0
Deduct 344 from 365 and we're left with 21.
Grab the next digit (0) from the dividend, add it to 21, then carry on: 210 / 43

On to step 6:
When dividing 210 by 43, we get 4 with a remainder of 38.
Write down 4 as next digit of the result. 
Result so far: 4084.0
Subtract 172 from 210 to get 38.
Include the next digit (7) from the dividend after 38, then repeat: 387 / 43

Going ahead to step 7:
43 can be fit into 387 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 40849.0
If we take 387 away from 387, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 43

Advancing to step 8:
43 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 408490.0
Deduct 0 from 2 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
43 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 408490.0
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
200 divided by 43 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 408490.04
Subtracting 172 from 200 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 11:
43 can be fit into 280 6 times, resulting in a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 408490.046
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
43 can be fit into 220 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 408490.0465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 13:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 408490.04651
Subtract 43 from 50 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 14:
43 goes into 70 1 times with a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 408490.046511
The remainder is 27 after subtracting 43 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 408490.046511 with a remainder of 2.7e-06.
