501232 divided by 43 
The aim is to understand the frequency of 43 in 501232.

On to step 1:
5 divided by 43 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 43

On to step 2:
43 goes into 50 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 43 from 50 leaves us with 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 43

Advancing to step 3:
71 divided by 43 is 1 with a remainder of 28.
Put 1 as the next digit of the answer. 
Result so far: 11.0
If we subtract 43 from 71, we get 28.
Grab the next digit (2) from the dividend, add it to 28, then carry on: 282 / 43

Step 4:
When dividing 282 by 43, we get 6 with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 116.0
If we take 258 away from 282, we end up with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 43

Advancing to step 5:
43 can be fit into 243 5 times, resulting in a remainder of 28.
Put 5 as the next digit of the answer. 
Result so far: 1165.0
Deduct 215 from 243 and we're left with 28.
Bring next digit (2) of the dividend behind the 28 and repeat the process: 282 / 43

Going ahead to step 6:
282 divided by 43 is 6 with a remainder of 24.
Record the quotient 6 as the next digit in the result. 
Result so far: 11656.0
The remainder is 24 after subtracting 258 from 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
240 divided by 43 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 11656.5
The remainder is 25 after subtracting 215 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
43 can be fit into 250 5 times, resulting in a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 11656.55
If we take 215 away from 250, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

After the division, we end up with 11656.55 and a remainder of 0.035.
