We look at the division of 209832 by 43 
The aim is to understand the frequency of 43 in 209832.

Step 1:
2 divided by 43 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 43

Step 2:
20 divided by 43 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 20 and we're left with 20.
Include the next digit (9) from the dividend after 20, then repeat: 209 / 43

Step 3:
209 divided by 43 is 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 172 from 209, we get 37.
Include the next digit (8) from the dividend after 37, then repeat: 378 / 43

Let's proceed to step 4:
43 can be fit into 378 8 times, resulting in a remainder of 34.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Subtracting 344 from 378 leaves us with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 43

Moving on to step 5:
The number 43 fits into 343 7 times, leaving a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 487.0
Subtract 301 from 343 to get 42.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 43

Step 6:
43 goes into 422 9 times with a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 4879.0
Deduct 387 from 422 and we're left 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.

Going ahead to step 7:
350 divided by 43 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 4879.8
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
60 divided by 43 is 1 with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 4879.81
Subtract 43 from 60 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
43 can be fit into 170 3 times, resulting in a remainder of 41.
The number 3 becomes the next digit in our result. 
Result so far: 4879.813
Deduct 129 from 170 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 10:
When dividing 410 by 43, we get 9 with a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 4879.8139
The remainder is 23 after subtracting 387 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

On to step 11:
The number 43 fits into 230 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 4879.81395
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 12:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 4879.813953
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
The number 43 fits into 210 4 times, leaving a remainder of 38.
The next digit of our result is 4. 
Result so far: 4879.8139534
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 14:
380 divided by 43 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 4879.81395348
Subtracting 344 from 380 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 4879.81395348, with a leftover of 3.6e-08.
