We're dividing 574356 by 43 
The aim is to understand the frequency of 43 in 574356.

Step 1:
If we divide 5 by 43, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 43

Moving on to step 2:
If we divide 57 by 43, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 43 from 57 to get 14.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 43

Going ahead to step 3:
43 can be fit into 144 3 times, resulting in a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 129 from 144, we get 15.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 43

Moving on to step 4:
43 goes into 153 3 times with a remainder of 24.
Put 3 as the next digit of the answer. 
Result so far: 133.0
The remainder is 24 after subtracting 129 from 153.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 43

Let's proceed to step 5:
If we divide 245 by 43, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 1335.0
If we subtract 215 from 245, we get 30.
Grab the next digit (6) from the dividend, add it to 30, then carry on: 306 / 43

Step 6:
If we divide 306 by 43, we get 7 and a remainder of 5.
The next digit of our result is 7. 
Result so far: 13357.0
The remainder is 5 after subtracting 301 from 306.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
When dividing 50 by 43, we get 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 13357.1
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.

Advancing to step 8:
When dividing 70 by 43, we get 1 with a remainder of 27.
The next digit of our result is 1. 
Result so far: 13357.11
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 13357.11 with a remainder of 0.027.
