We look at the division of 566169 by 43 
The aim is to understand the frequency of 43 in 566169.

Let's proceed to step 1:
43 goes into 5 0 times with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 43

Going ahead to step 2:
When dividing 56 by 43, we get 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 13 after subtracting 43 from 56.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 43

Advancing to step 3:
43 goes into 136 3 times with a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 129 from 136, we get 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 43

Moving on to step 4:
The number 43 fits into 71 1 times, leaving a remainder of 28.
Write down 1 as next digit of the result. 
Result so far: 131.0
Subtracting 43 from 71 leaves us with 28.
Fetch the next digit (6) from the dividend, attach it to 28 and continue: 286 / 43

Moving on to step 5:
43 goes into 286 6 times with a remainder of 28.
The number 6 becomes the next digit in our result. 
Result so far: 1316.0
If we subtract 258 from 286, we get 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 43

Step 6:
289 divided by 43 is 6 with a remainder of 31.
The next digit of our result is 6. 
Result so far: 13166.0
Subtracting 258 from 289 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 7:
When dividing 310 by 43, we get 7 with a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 13166.7
Subtract 301 from 310 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
90 divided by 43 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 13166.72
Deduct 86 from 90 and we're left 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.

Going ahead to step 9:
When dividing 40 by 43, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 13166.72
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 10:
The number 43 fits into 400 9 times, leaving a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 13166.7209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 11:
If we divide 130 by 43, we get 3 and a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 13166.72093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
If we divide 10 by 43, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 13166.72093
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.

Advancing to step 13:
When dividing 100 by 43, we get 2 with a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 13166.7209302
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.

On to step 14:
140 divided by 43 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 13166.72093023
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.

The quotient of the division is 13166.72093023, and the remainder is 1.1e-08.
