We're dividing 224517 by 43 
The aim is to understand the frequency of 43 in 224517.

On to step 1:
The number 43 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
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

Moving on to step 2:
43 can be fit into 22 0 times, resulting in a remainder of 22.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 22 leaves us with 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 43

Let's proceed to step 3:
If we divide 224 by 43, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 215 from 224 leaves us with 9.
Append the next digit (5) from the dividend to 9 and continue with: 95 / 43

Moving on to step 4:
43 can be fit into 95 2 times, resulting in a remainder of 9.
The number 2 becomes the next digit in our result. 
Result so far: 52.0
Subtracting 86 from 95 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 43

Step 5:
When dividing 91 by 43, we get 2 with a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 522.0
Subtracting 86 from 91 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 43

On to step 6:
When dividing 57 by 43, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 5221.0
Subtract 43 from 57 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
43 can be fit into 140 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 5221.3
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
When dividing 110 by 43, we get 2 with a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 5221.32
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
When dividing 240 by 43, we get 5 with a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5221.325
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.

Step 10:
If we divide 250 by 43, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 5221.3255
Subtracting 215 from 250 leaves us 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 5221.3255 and a remainder of 0.00035.
