105449 ÷ 23 
The aim is to understand the frequency of 23 in 105449.

Moving on to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 23

Going ahead to step 2:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 23

Going ahead to step 3:
The number 23 fits into 105 4 times, leaving a remainder of 13.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Deduct 92 from 105 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 23

On to step 4:
The number 23 fits into 134 5 times, leaving a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 45.0
The remainder is 19 after subtracting 115 from 134.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 23

Moving on to step 5:
194 divided by 23 is 8 with a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 458.0
Subtracting 184 from 194 leaves us with 10.
Fetch the next digit (9) from the dividend, attach it to 10 and continue: 109 / 23

Let's proceed to step 6:
If we divide 109 by 23, we get 4 and a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 4584.0
Deduct 92 from 109 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
23 goes into 170 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 4584.7
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 8:
90 divided by 23 is 3 with a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 4584.73
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 9:
When dividing 210 by 23, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 4584.739
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 4584.7391
If we subtract 23 from 30, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 11:
23 goes into 70 3 times with a remainder of 1.
The next digit of our result is 3. 
Result so far: 4584.73913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 12:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4584.73913
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.

Let's proceed to step 13:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 4584.7391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
23 goes into 80 3 times with a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 4584.73913043
If we take 69 away from 80, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final outcome is 4584.73913043, with a leftover of 1.1e-08.
