239273 divided by 23 
The aim is to understand the frequency of 23 in 239273.

Advancing to 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
Deduct 0 from 2 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 23

On to step 2:
23 can be fit into 23 1 times, resulting in a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 23 from 23, we get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 23

Going ahead to step 3:
23 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (2) from the dividend, attach it to 9 and continue: 92 / 23

Advancing to step 4:
23 can be fit into 92 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 104.0
The remainder is 0 after subtracting 92 from 92.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 23

On to step 5:
The number 23 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 1040.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 23

Going ahead to step 6:
23 goes into 73 3 times with a remainder of 4.
The next digit of our result is 3. 
Result so far: 10403.0
Deduct 69 from 73 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 7:
When dividing 40 by 23, we get 1 with a remainder of 17.
Use 1 as the next digit of our solution. 
Result so far: 10403.1
The remainder is 17 after subtracting 23 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 8:
When dividing 170 by 23, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 10403.17
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.

Advancing to step 9:
The number 23 fits into 90 3 times, leaving a remainder of 21.
Put 3 as the next digit of the answer. 
Result so far: 10403.173
Subtract 69 from 90 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 10:
The number 23 fits into 210 9 times, leaving a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 10403.1739
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.

Step 11:
23 goes into 30 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 10403.17391
If we take 23 away from 30, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
When dividing 70 by 23, we get 3 with a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 10403.173913
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.

Advancing to step 13:
23 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 10403.173913
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.

On to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 10403.17391304
Subtracting 92 from 100 leaves us 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.

After the division, we end up with 10403.17391304 and a remainder of 8e-09.
