We look at the division of 720517 by 43 
The aim is to understand the frequency of 43 in 720517.

On to step 1:
43 goes into 7 0 times with 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.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 43

Step 2:
The number 43 fits into 72 1 times, leaving a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 72 leaves us with 29.
Take the next digit (0) from the dividend and append it to 29, then repeat: 290 / 43

Step 3:
The number 43 fits into 290 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 16.0
If we subtract 258 from 290, we get 32.
Fetch the next digit (5) from the dividend, attach it to 32 and continue: 325 / 43

Going ahead to step 4:
325 divided by 43 is 7 with a remainder of 24.
Write down 7 as next digit of the result. 
Result so far: 167.0
Subtracting 301 from 325 leaves us with 24.
Bring next digit (1) of the dividend behind the 24 and repeat the process: 241 / 43

Moving on to step 5:
43 goes into 241 5 times with a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 1675.0
Subtract 215 from 241 to get 26.
Fetch the next digit (7) from the dividend, attach it to 26 and continue: 267 / 43

Let's proceed to step 6:
The number 43 fits into 267 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16756.0
Subtract 258 from 267 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
90 divided by 43 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 16756.2
Subtract 86 from 90 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
40 divided by 43 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 16756.2
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
400 divided by 43 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 16756.209
Subtract 387 from 400 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
43 can be fit into 130 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 16756.2093
If we take 129 away from 130, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 11:
43 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 16756.2093
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
If we divide 100 by 43, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 16756.209302
The remainder is 14 after subtracting 86 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 13:
When dividing 140 by 43, we get 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 16756.2093023
Subtracting 129 from 140 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 14:
43 goes into 110 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 16756.20930232
The remainder is 24 after subtracting 86 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 16756.20930232 with a remainder of 2.4e-08.
