We're dividing 259481 by 23 
The aim is to understand the frequency of 23 in 259481.

Moving on to step 1:
The number 23 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 23

On to step 2:
23 goes into 25 1 times with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 23 from 25 leaves us with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 23

Let's proceed to step 3:
23 goes into 29 1 times with a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 11.0
If we subtract 23 from 29, we get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 23

Going ahead to step 4:
23 can be fit into 64 2 times, resulting in a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 112.0
If we subtract 46 from 64, we get 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 23

Going ahead to step 5:
When dividing 188 by 23, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 1128.0
Deduct 184 from 188 and we're left with 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 23

Moving on to step 6:
If we divide 41 by 23, we get 1 and a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 11281.0
Subtract 23 from 41 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
180 divided by 23 is 7 with a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 11281.7
If we subtract 161 from 180, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 8:
190 divided by 23 is 8 with a remainder of 6.
The next digit of our result is 8. 
Result so far: 11281.78
Deduct 184 from 190 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
When dividing 60 by 23, we get 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 11281.782
If we subtract 46 from 60, we 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.

Step 10:
When dividing 140 by 23, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 11281.7826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
When dividing 20 by 23, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 11281.7826
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
200 divided by 23 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 11281.782608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 13:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 11281.7826086
If we take 138 away from 160, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 11281.78260869
If we subtract 207 from 220, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 11281.78260869 and a remainder of 1.3e-08.
