665325 ÷ 23 
The aim is to understand the frequency of 23 in 665325.

Let's proceed to step 1:
If we divide 6 by 23, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 23

Step 2:
66 divided by 23 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 46 from 66 and we're left with 20.
Include the next digit (5) from the dividend after 20, then repeat: 205 / 23

Step 3:
23 can be fit into 205 8 times, resulting in a remainder of 21.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
If we take 184 away from 205, we end up with 21.
Take the next digit (3) from the dividend and append it to 21, then repeat: 213 / 23

On to step 4:
213 divided by 23 is 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 289.0
Subtracting 207 from 213 leaves us with 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 23

Let's proceed to step 5:
23 can be fit into 62 2 times, resulting in a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 2892.0
Subtracting 46 from 62 leaves us with 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 23

Moving on to step 6:
When dividing 165 by 23, we get 7 with a remainder of 4.
Record the quotient 7 as the next digit in the result. 
Result so far: 28927.0
Subtracting 161 from 165 leaves us 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.

Step 7:
23 can be fit into 40 1 times, resulting in a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 28927.1
Subtract 23 from 40 to get 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 8:
170 divided by 23 is 7 with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 28927.17
Subtracting 161 from 170 leaves us 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.

Advancing to step 9:
23 goes into 90 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 28927.173
If we take 69 away from 90, we end up 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.

Step 10:
If we divide 210 by 23, we get 9 and a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 28927.1739
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.

On to step 11:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 28927.17391
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.

Step 12:
70 divided by 23 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 28927.173913
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.

Let's proceed to step 13:
23 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 28927.173913
If we take 0 away from 10, we end up 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.

Let's proceed to step 14:
When dividing 100 by 23, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 28927.17391304
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.

In conclusion, the division gives 28927.17391304 with a balance of 8e-09.
