We're dividing 228411 by 43 
The aim is to understand the frequency of 43 in 228411.

On to step 1:
If we divide 2 by 43, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 43

On to step 2:
22 divided by 43 is 0 with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 22, we end up with 22.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 43

On to step 3:
The number 43 fits into 228 5 times, leaving a remainder of 13.
Use 5 as the next digit of our solution. 
Result so far: 5.0
If we subtract 215 from 228, we get 13.
Include the next digit (4) from the dividend after 13, then repeat: 134 / 43

Advancing to step 4:
If we divide 134 by 43, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 53.0
The remainder is 5 after subtracting 129 from 134.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 43

Going ahead to step 5:
If we divide 51 by 43, we get 1 and a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 531.0
The remainder is 8 after subtracting 43 from 51.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 43

Let's proceed to step 6:
If we divide 81 by 43, we get 1 and a remainder of 38.
The next digit of our result is 1. 
Result so far: 5311.0
If we subtract 43 from 81, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 7:
When dividing 380 by 43, we get 8 with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 5311.8
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 8:
360 divided by 43 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 5311.88
If we take 344 away from 360, we end up 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.

The final result is 5311.88 with a remainder of 0.016.
