Let's divide 458089 by 23
The aim is to understand the frequency of 23 in 458089.

Going ahead to step 1:
23 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 23

Let's proceed to step 2:
45 divided by 23 is 1 with a remainder of 22.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 23 from 45, we get 22.
Include the next digit (8) from the dividend after 22, then repeat: 228 / 23

Advancing to step 3:
The number 23 fits into 228 9 times, leaving a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 19.0
If we subtract 207 from 228, we get 21.
Append the next digit (0) from the dividend to 21 and continue with: 210 / 23

Going ahead to step 4:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 199.0
Subtracting 207 from 210 leaves us with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 23

Going ahead to step 5:
23 can be fit into 38 1 times, resulting in a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 1991.0
The remainder is 15 after subtracting 23 from 38.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 23

Moving on to step 6:
23 goes into 159 6 times with a remainder of 21.
Use 6 as the next digit of our solution. 
Result so far: 19916.0
Subtracting 138 from 159 leaves us 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.

Let's proceed to step 7:
23 can be fit into 210 9 times, resulting in a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 19916.9
The remainder is 3 after subtracting 207 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 19916.91
Subtract 23 from 30 to 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 9:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 19916.913
Subtract 69 from 70 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
23 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 19916.913
Subtract 0 from 10 to 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 11:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 19916.91304
Deduct 92 from 100 and we're left 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.

Advancing to step 12:
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: 19916.913043
If we subtract 69 from 80, 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 13:
23 goes into 110 4 times with a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 19916.9130434
The remainder is 18 after subtracting 92 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 14:
When dividing 180 by 23, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 19916.91304347
Subtracting 161 from 180 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.

The final outcome is 19916.91304347, with a leftover of 1.9e-08.
