Let's divide 75909831 by 43
The aim is to understand the frequency of 43 in 75909831.

Moving on to step 1:
43 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 43

On to step 2:
When dividing 75 by 43, we get 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 75, we end up with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 43

On to step 3:
If we divide 329 by 43, we get 7 and a remainder of 28.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 301 away from 329, we end up with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 43

Advancing to step 4:
43 goes into 280 6 times with a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 176.0
If we subtract 258 from 280, we get 22.
Include the next digit (9) from the dividend after 22, then repeat: 229 / 43

Step 5:
229 divided by 43 is 5 with a remainder of 14.
Write down 5 as next digit of the result. 
Result so far: 1765.0
If we take 215 away from 229, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 43

On to step 6:
43 goes into 148 3 times with a remainder of 19.
Put 3 as the next digit of the answer. 
Result so far: 17653.0
If we subtract 129 from 148, we get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 43

Going ahead to step 7:
When dividing 193 by 43, we get 4 with a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 176534.0
Subtracting 172 from 193 leaves us with 21.
Grab the next digit (1) from the dividend, add it to 21, then carry on: 211 / 43

Let's proceed to step 8:
When dividing 211 by 43, we get 4 with a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 1765344.0
The remainder is 39 after subtracting 172 from 211.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
43 can be fit into 390 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 1765344.9
Subtracting 387 from 390 leaves us 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.

Moving on to step 10:
When dividing 30 by 43, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 1765344.9
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 11:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 1765344.906
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 12:
If we divide 420 by 43, we get 9 and a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 1765344.9069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 13:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1765344.90697
Deduct 301 from 330 and we're left 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.

Advancing to step 14:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 1765344.906976
Subtract 258 from 290 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 15:
43 goes into 320 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 1765344.9069767
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.

Let's proceed to step 16:
The number 43 fits into 190 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 1765344.90697674
If we take 172 away from 190, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 1765344.90697674 and a remainder of 1.8e-08.
