We look at the division of 745317 by 43 
The aim is to understand the frequency of 43 in 745317.

Going ahead to step 1:
If we divide 7 by 43, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 43

Let's proceed to step 2:
74 divided by 43 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 43 from 74 leaves us with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 43

Going ahead to step 3:
If we divide 315 by 43, we get 7 and a remainder of 14.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 301 from 315 leaves us with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 43

Moving on to step 4:
43 can be fit into 143 3 times, resulting in a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 173.0
If we take 129 away from 143, we end up with 14.
Append the next digit (1) from the dividend to 14 and continue with: 141 / 43

Advancing to step 5:
The number 43 fits into 141 3 times, leaving a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 1733.0
If we subtract 129 from 141, we get 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 43

Let's proceed to step 6:
43 can be fit into 127 2 times, resulting in a remainder of 41.
The next digit of our result is 2. 
Result so far: 17332.0
The remainder is 41 after subtracting 86 from 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 7:
The number 43 fits into 410 9 times, leaving a remainder of 23.
The number 9 becomes the next digit in our result. 
Result so far: 17332.9
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 8:
The number 43 fits into 230 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 17332.95
Subtract 215 from 230 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
150 divided by 43 is 3 with a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 17332.953
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
210 divided by 43 is 4 with a remainder of 38.
Record the quotient 4 as the next digit in the result. 
Result so far: 17332.9534
Deduct 172 from 210 and we're left 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.

Moving on to step 11:
When dividing 380 by 43, we get 8 with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 17332.95348
If we subtract 344 from 380, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 12:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 17332.953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 17332.953488 with a remaining 1.6e-06.
