Let's divide 805123 by 43
The aim is to understand the frequency of 43 in 805123.

Moving on to step 1:
If we divide 8 by 43, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 43

Step 2:
43 can be fit into 80 1 times, resulting in a remainder of 37.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 80 leaves us with 37.
Grab the next digit (5) from the dividend, add it to 37, then carry on: 375 / 43

Let's proceed to step 3:
43 goes into 375 8 times with a remainder of 31.
Write down 8 as next digit of the result. 
Result so far: 18.0
If we subtract 344 from 375, we get 31.
Grab the next digit (1) from the dividend, add it to 31, then carry on: 311 / 43

Let's proceed to step 4:
43 can be fit into 311 7 times, resulting in a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
The remainder is 10 after subtracting 301 from 311.
Bring next digit (2) of the dividend behind the 10 and repeat the process: 102 / 43

Advancing to step 5:
43 goes into 102 2 times with a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 1872.0
Subtracting 86 from 102 leaves us with 16.
Take the next digit (3) from the dividend and append it to 16, then repeat: 163 / 43

On to step 6:
43 can be fit into 163 3 times, resulting in a remainder of 34.
The number 3 becomes the next digit in our result. 
Result so far: 18723.0
Subtract 129 from 163 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
When dividing 340 by 43, we get 7 with a remainder of 39.
Use 7 as the next digit of our solution. 
Result so far: 18723.7
If we subtract 301 from 340, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 8:
The number 43 fits into 390 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 18723.79
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 9:
43 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 18723.79
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 10:
If we divide 300 by 43, we get 6 and a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 18723.7906
Subtract 258 from 300 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 43 is 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 18723.79069
Subtract 387 from 420 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Advancing to step 12:
330 divided by 43 is 7 with a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 18723.790697
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 13:
43 goes into 290 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 18723.7906976
If we take 258 away from 290, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 14:
If we divide 320 by 43, we get 7 and a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 18723.79069767
The remainder is 19 after subtracting 301 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final result is 18723.79069767 with a remainder of 1.9e-08.
