We're dividing 402892 by 43 
The aim is to understand the frequency of 43 in 402892.

Going ahead to step 1:
The number 43 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 43

Step 2:
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: 0.0
The remainder is 40 after subtracting 0 from 40.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 43

Advancing to step 3:
If we divide 402 by 43, we get 9 and a remainder of 15.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 387 from 402 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 43

Step 4:
43 goes into 158 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
The remainder is 29 after subtracting 129 from 158.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 43

Going ahead to step 5:
When dividing 299 by 43, we get 6 with a remainder of 41.
Use 6 as the next digit of our solution. 
Result so far: 936.0
Subtract 258 from 299 to get 41.
Fetch the next digit (2) from the dividend, attach it to 41 and continue: 412 / 43

Going ahead to step 6:
The number 43 fits into 412 9 times, leaving a remainder of 25.
Put 9 as the next digit of the answer. 
Result so far: 9369.0
The remainder is 25 after subtracting 387 from 412.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 7:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9369.5
If we subtract 215 from 250, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
When dividing 350 by 43, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 9369.58
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
43 goes into 60 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 9369.581
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.

Moving on to step 10:
When dividing 170 by 43, we get 3 with a remainder of 41.
The next digit of our result is 3. 
Result so far: 9369.5813
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Moving on to step 11:
43 can be fit into 410 9 times, resulting in a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9369.58139
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 12:
When dividing 230 by 43, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9369.581395
Subtracting 215 from 230 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 13:
43 goes into 150 3 times with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 9369.5813953
Subtracting 129 from 150 leaves us 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.

Advancing to step 14:
43 can be fit into 210 4 times, resulting in a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 9369.58139534
If we take 172 away from 210, we end up 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.

After the division, we end up with 9369.58139534 and a remainder of 3.8e-08.
