We're dividing 223933 by 23 
The aim is to understand the frequency of 23 in 223933.

Step 1:
2 divided by 23 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 23

Going ahead to step 2:
23 can be fit into 22 0 times, resulting in a remainder of 22.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 22, we get 22.
Take the next digit (3) from the dividend and append it to 22, then repeat: 223 / 23

Moving on to step 3:
The number 23 fits into 223 9 times, leaving a remainder of 16.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 207 from 223 leaves us with 16.
Bring next digit (9) of the dividend behind the 16 and repeat the process: 169 / 23

Advancing to step 4:
23 goes into 169 7 times with a remainder of 8.
Write down 7 as next digit of the result. 
Result so far: 97.0
Subtracting 161 from 169 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 23

Moving on to step 5:
23 goes into 83 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 973.0
Subtract 69 from 83 to get 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 23

Moving on to step 6:
23 can be fit into 143 6 times, resulting in a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 9736.0
Subtract 138 from 143 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
If we divide 50 by 23, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9736.2
Subtract 46 from 50 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
If we divide 40 by 23, we get 1 and a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 9736.21
Deduct 23 from 40 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.

On to step 9:
23 can be fit into 170 7 times, resulting in a remainder of 9.
Use 7 as the next digit of our solution. 
Result so far: 9736.217
If we take 161 away from 170, we end up with 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 10:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 9736.2173
Deduct 69 from 90 and we're left 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.

Moving on to step 11:
When dividing 210 by 23, we get 9 with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 9736.21739
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 12:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 9736.217391
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.

On to step 13:
70 divided by 23 is 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 9736.2173913
If we take 69 away from 70, we end up 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 14:
23 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 9736.2173913
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.

After the division, we end up with 9736.2173913 and a remainder of 1e-08.
