We look at the division of 807193 by 43 
The aim is to understand the frequency of 43 in 807193.

Moving on to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (0) of the dividend behind the 8 and repeat the process: 80 / 43

On to step 2:
If we divide 80 by 43, we get 1 and a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 43 from 80, we get 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 43

Going ahead to step 3:
43 can be fit into 377 8 times, resulting in a remainder of 33.
The next digit of our result is 8. 
Result so far: 18.0
Subtracting 344 from 377 leaves us with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 43

On to step 4:
When dividing 331 by 43, we get 7 with a remainder of 30.
Use 7 as the next digit of our solution. 
Result so far: 187.0
If we subtract 301 from 331, we get 30.
Include the next digit (9) from the dividend after 30, then repeat: 309 / 43

Going ahead to step 5:
43 can be fit into 309 7 times, resulting in a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 1877.0
Subtract 301 from 309 to get 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 43

Let's proceed to step 6:
43 can be fit into 83 1 times, resulting in a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 18771.0
The remainder is 40 after subtracting 43 from 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 7:
If we divide 400 by 43, we get 9 and a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 18771.9
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.

Moving on to step 8:
130 divided by 43 is 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 18771.93
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 9:
43 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18771.93
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.

Step 10:
If we divide 100 by 43, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 18771.9302
Subtract 86 from 100 to get 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 11:
If we divide 140 by 43, we get 3 and a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 18771.93023
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.

Step 12:
If we divide 110 by 43, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 18771.930232
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 13:
43 can be fit into 240 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 18771.9302325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 14:
43 goes into 250 5 times with a remainder of 35.
The next digit of our result is 5. 
Result so far: 18771.93023255
Deduct 215 from 250 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.

The quotient of the division is 18771.93023255, and the remainder is 3.5e-08.
