We're dividing 507594 by 23 
The aim is to understand the frequency of 23 in 507594.

Advancing to step 1:
5 divided by 23 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 23

Advancing to step 2:
When dividing 50 by 23, we get 2 with a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 4 after subtracting 46 from 50.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 23

On to step 3:
23 can be fit into 47 2 times, resulting in a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 46 from 47, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 23

Moving on to step 4:
23 can be fit into 15 0 times, resulting in a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 220.0
If we subtract 0 from 15, we get 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 23

Step 5:
23 can be fit into 159 6 times, resulting in a remainder of 21.
The number 6 becomes the next digit in our result. 
Result so far: 2206.0
If we take 138 away from 159, we end up with 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 23

Step 6:
23 goes into 214 9 times with a remainder of 7.
The next digit of our result is 9. 
Result so far: 22069.0
The remainder is 7 after subtracting 207 from 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 22069.3
If we subtract 69 from 70, we 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.

Let's proceed to step 8:
23 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 22069.3
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 9:
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: 22069.304
If we subtract 92 from 100, we 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.

Step 10:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 22069.3043
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.

Moving on to step 11:
110 divided by 23 is 4 with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 22069.30434
Subtracting 92 from 110 leaves us 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.

Advancing to step 12:
When dividing 180 by 23, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 22069.304347
Subtract 161 from 180 to 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.

On to step 13:
23 goes into 190 8 times with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 22069.3043478
If we take 184 away from 190, we end up 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.

Step 14:
60 divided by 23 is 2 with a remainder of 14.
The next digit of our result is 2. 
Result so far: 22069.30434782
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.

In conclusion, the division gives 22069.30434782 with a balance of 1.4e-08.
