We look at the division of 654402 by 23 
The aim is to understand the frequency of 23 in 654402.

Let's proceed to step 1:
The number 23 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 23

Let's proceed to step 2:
23 can be fit into 65 2 times, resulting in a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 46 from 65 and we're left with 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 23

On to step 3:
If we divide 194 by 23, we get 8 and a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtracting 184 from 194 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 23

Let's proceed to step 4:
The number 23 fits into 104 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 284.0
Subtracting 92 from 104 leaves us with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 23

On to step 5:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2845.0
The remainder is 5 after subtracting 115 from 120.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 23

Going ahead to step 6:
52 divided by 23 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 28452.0
Subtract 46 from 52 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
If we divide 60 by 23, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 28452.2
Deduct 46 from 60 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 8:
23 goes into 140 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 28452.26
Subtracting 138 from 140 leaves us 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.

Let's proceed to step 9:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 28452.26
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.

Going ahead to step 10:
The number 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 28452.2608
If we subtract 184 from 200, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 11:
If we divide 160 by 23, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 28452.26086
Deduct 138 from 160 and we're left 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 12:
220 divided by 23 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 28452.260869
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.

Moving on to step 13:
When dividing 130 by 23, we get 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 28452.2608695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 14:
150 divided by 23 is 6 with a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 28452.26086956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 28452.26086956 with a balance of 1.2e-08.
