Let's divide 254479 by 23
The aim is to understand the frequency of 23 in 254479.

Step 1:
2 divided by 23 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 23

Moving on to step 2:
23 goes into 25 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 2 after subtracting 23 from 25.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 23

Advancing to step 3:
When dividing 24 by 23, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 23 from 24, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 23

On to step 4:
When dividing 14 by 23, we get 0 with a remainder of 14.
Put 0 as the next digit of the answer. 
Result so far: 110.0
Subtracting 0 from 14 leaves us with 14.
Bring next digit (7) of the dividend behind the 14 and repeat the process: 147 / 23

On to step 5:
147 divided by 23 is 6 with a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1106.0
If we subtract 138 from 147, we get 9.
Fetch the next digit (9) from the dividend, attach it to 9 and continue: 99 / 23

Let's proceed to step 6:
When dividing 99 by 23, we get 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 11064.0
Subtracting 92 from 99 leaves us 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.

On to step 7:
23 can be fit into 70 3 times, resulting in a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 11064.3
Deduct 69 from 70 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 8:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 11064.3
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11064.304
If we take 92 away from 100, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 10:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 11064.3043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 11:
When dividing 110 by 23, we get 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 11064.30434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 12:
The number 23 fits into 180 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 11064.304347
The remainder is 19 after subtracting 161 from 180.
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 13:
When dividing 190 by 23, we get 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 11064.3043478
The remainder is 6 after subtracting 184 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The next digit of our result is 2. 
Result so far: 11064.30434782
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final outcome is 11064.30434782, with a leftover of 1.4e-08.
