765124 ÷ 43 
The aim is to understand the frequency of 43 in 765124.

Let's proceed to step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 43

Let's proceed to step 2:
43 can be fit into 76 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 43 away from 76, we end up with 33.
Take the next digit (5) from the dividend and append it to 33, then repeat: 335 / 43

Let's proceed to step 3:
When dividing 335 by 43, we get 7 with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
The remainder is 34 after subtracting 301 from 335.
Bring next digit (1) of the dividend behind the 34 and repeat the process: 341 / 43

Step 4:
The number 43 fits into 341 7 times, leaving a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
The remainder is 40 after subtracting 301 from 341.
Append the next digit (2) from the dividend to 40 and continue with: 402 / 43

Advancing to step 5:
43 goes into 402 9 times with a remainder of 15.
The next digit of our result is 9. 
Result so far: 1779.0
Subtract 387 from 402 to get 15.
Grab the next digit (4) from the dividend, add it to 15, then carry on: 154 / 43

Going ahead to step 6:
43 can be fit into 154 3 times, resulting in a remainder of 25.
The next digit of our result is 3. 
Result so far: 17793.0
Subtract 129 from 154 to 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 7:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 17793.5
Subtract 215 from 250 to 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.

Moving on to step 8:
If we divide 350 by 43, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 17793.58
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.

Step 9:
43 can be fit into 60 1 times, resulting in a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 17793.581
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.

Step 10:
The number 43 fits into 170 3 times, leaving a remainder of 41.
Use 3 as the next digit of our solution. 
Result so far: 17793.5813
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.

Going ahead to step 11:
The number 43 fits into 410 9 times, leaving a remainder of 23.
Write down 9 as next digit of the result. 
Result so far: 17793.58139
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.

Moving on to step 12:
230 divided by 43 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 17793.581395
If we take 215 away from 230, we end up 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.

Advancing to step 13:
43 can be fit into 150 3 times, resulting in a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 17793.5813953
The remainder is 21 after subtracting 129 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 14:
When dividing 210 by 43, we get 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 17793.58139534
Subtracting 172 from 210 leaves us 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.

The final result is 17793.58139534 with a remainder of 3.8e-08.
