We look at the division of 742329 by 43 
The aim is to understand the frequency of 43 in 742329.

Let's proceed to step 1:
43 can be fit into 7 0 times, resulting in a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 43

Advancing to step 2:
The number 43 fits into 74 1 times, leaving a remainder of 31.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 43 from 74, we get 31.
Fetch the next digit (2) from the dividend, attach it to 31 and continue: 312 / 43

Advancing to step 3:
43 can be fit into 312 7 times, resulting in a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 17.0
If we take 301 away from 312, we end up with 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 43

Advancing to step 4:
If we divide 113 by 43, we get 2 and a remainder of 27.
The number 2 becomes the next digit in our result. 
Result so far: 172.0
Subtracting 86 from 113 leaves us with 27.
Bring next digit (2) of the dividend behind the 27 and repeat the process: 272 / 43

On to step 5:
272 divided by 43 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 1726.0
The remainder is 14 after subtracting 258 from 272.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 43

Going ahead to step 6:
If we divide 149 by 43, we get 3 and a remainder of 20.
Put 3 as the next digit of the answer. 
Result so far: 17263.0
If we take 129 away from 149, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 7:
The number 43 fits into 200 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 17263.4
Deduct 172 from 200 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Step 8:
43 goes into 280 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 17263.46
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.

On to step 9:
The number 43 fits into 220 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 17263.465
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 10:
43 can be fit into 50 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 17263.4651
Deduct 43 from 50 and we're left 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.

Advancing to step 11:
43 can be fit into 70 1 times, resulting in a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 17263.46511
Deduct 43 from 70 and we're left with 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 outcome is 17263.46511, with a leftover of 2.7e-05.
