We look at the division of 216923 by 43 
The aim is to understand the frequency of 43 in 216923.

Moving on to step 1:
43 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 43

Advancing to step 2:
When dividing 21 by 43, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 43

On to step 3:
216 divided by 43 is 5 with a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 215 from 216 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 43

Step 4:
43 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 50.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 43

Let's proceed to step 5:
The number 43 fits into 192 4 times, leaving a remainder of 20.
The next digit of our result is 4. 
Result so far: 504.0
If we subtract 172 from 192, we get 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 43

Going ahead to step 6:
The number 43 fits into 203 4 times, leaving a remainder of 31.
Write down 4 as next digit of the result. 
Result so far: 5044.0
If we subtract 172 from 203, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 43, we get 7 with a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 5044.7
The remainder is 9 after subtracting 301 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
If we divide 90 by 43, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 5044.72
If we subtract 86 from 90, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
40 divided by 43 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5044.72
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.

Let's proceed to step 10:
400 divided by 43 is 9 with a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 5044.7209
If we take 387 away from 400, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 11:
43 can be fit into 130 3 times, resulting in a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 5044.72093
Subtracting 129 from 130 leaves us 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.

Going ahead to step 12:
10 divided by 43 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 5044.72093
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 13:
When dividing 100 by 43, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 5044.7209302
If we take 86 away from 100, we end up 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.

Advancing to step 14:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The next digit of our result is 3. 
Result so far: 5044.72093023
Deduct 129 from 140 and we're left 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 final result is 5044.72093023 with a remainder of 1.1e-08.
