We look at the division of 302232 by 43 
The aim is to understand the frequency of 43 in 302232.

Step 1:
43 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 43

On to step 2:
When dividing 30 by 43, we get 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Append the next digit (2) from the dividend to 30 and continue with: 302 / 43

Going ahead to step 3:
43 can be fit into 302 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
If we take 301 away from 302, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 43

Step 4:
When dividing 12 by 43, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
If we subtract 0 from 12, we get 12.
Bring next digit (3) of the dividend behind the 12 and repeat the process: 123 / 43

Let's proceed to step 5:
The number 43 fits into 123 2 times, leaving a remainder of 37.
Use 2 as the next digit of our solution. 
Result so far: 702.0
The remainder is 37 after subtracting 86 from 123.
Grab the next digit (2) from the dividend, add it to 37, then carry on: 372 / 43

On to step 6:
372 divided by 43 is 8 with a remainder of 28.
Record the quotient 8 as the next digit in the result. 
Result so far: 7028.0
The remainder is 28 after subtracting 344 from 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Going ahead to step 7:
When dividing 280 by 43, we get 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 7028.6
The remainder is 22 after subtracting 258 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
The number 43 fits into 220 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 7028.65
Subtracting 215 from 220 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 9:
If we divide 50 by 43, we get 1 and a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 7028.651
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
When dividing 70 by 43, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 7028.6511
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final result is 7028.6511 with a remainder of 0.00027.
