We look at the division of 469633 by 43 
The aim is to understand the frequency of 43 in 469633.

On to step 1:
43 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 43

Moving on to step 2:
46 divided by 43 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 3 after subtracting 43 from 46.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 43

On to step 3:
When dividing 39 by 43, we get 0 with a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 39 to get 39.
Bring next digit (6) of the dividend behind the 39 and repeat the process: 396 / 43

Let's proceed to step 4:
The number 43 fits into 396 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 109.0
If we take 387 away from 396, we end up with 9.
Fetch the next digit (3) from the dividend, attach it to 9 and continue: 93 / 43

On to step 5:
43 goes into 93 2 times with a remainder of 7.
Write down 2 as next digit of the result. 
Result so far: 1092.0
If we subtract 86 from 93, we get 7.
Bring next digit (3) of the dividend behind the 7 and repeat the process: 73 / 43

Moving on to step 6:
When dividing 73 by 43, we get 1 with a remainder of 30.
The next digit of our result is 1. 
Result so far: 10921.0
The remainder is 30 after subtracting 43 from 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 7:
When dividing 300 by 43, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 10921.6
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 8:
When dividing 420 by 43, we get 9 with a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 10921.69
Subtract 387 from 420 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
43 goes into 330 7 times with a remainder of 29.
Put 7 as the next digit of the answer. 
Result so far: 10921.697
If we subtract 301 from 330, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Step 10:
If we divide 290 by 43, we get 6 and a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 10921.6976
If we subtract 258 from 290, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 11:
43 goes into 320 7 times with a remainder of 19.
The next digit of our result is 7. 
Result so far: 10921.69767
Subtracting 301 from 320 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 12:
If we divide 190 by 43, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 10921.697674
The remainder is 18 after subtracting 172 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 13:
The number 43 fits into 180 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 10921.6976744
Subtract 172 from 180 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 10921.6976744 and a remainder of 8e-08.
