We look at the division of 623006 by 23 
The aim is to understand the frequency of 23 in 623006.

Advancing to step 1:
23 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (2) from the dividend and append it to 6, then repeat: 62 / 23

Step 2:
When dividing 62 by 23, we get 2 with a remainder of 16.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 46 from 62 to get 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 23

Let's proceed to step 3:
163 divided by 23 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 27.0
If we subtract 161 from 163, we get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 23

Moving on to step 4:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
If we subtract 0 from 20, we get 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 23

Going ahead to step 5:
200 divided by 23 is 8 with a remainder of 16.
The next digit of our result is 8. 
Result so far: 2708.0
Subtract 184 from 200 to get 16.
Bring next digit (6) of the dividend behind the 16 and repeat the process: 166 / 23

Step 6:
When dividing 166 by 23, we get 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 27087.0
If we subtract 161 from 166, we 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:
The number 23 fits into 50 2 times, leaving a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 27087.2
Subtracting 46 from 50 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.

Going ahead to step 8:
When dividing 40 by 23, we get 1 with a remainder of 17.
Write down 1 as next digit of the result. 
Result so far: 27087.21
Subtracting 23 from 40 leaves us 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.

Moving on to step 9:
23 goes into 170 7 times with a remainder of 9.
The next digit of our result is 7. 
Result so far: 27087.217
Subtract 161 from 170 to 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.

Let's proceed to step 10:
If we divide 90 by 23, we get 3 and a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 27087.2173
If we subtract 69 from 90, we 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 11:
23 can be fit into 210 9 times, resulting in a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 27087.21739
If we take 207 away from 210, we end up 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.

Going ahead to step 12:
23 goes into 30 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 27087.217391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
When dividing 70 by 23, we get 3 with a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 27087.2173913
Deduct 69 from 70 and we're left 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.

On to step 14:
23 can be fit into 10 0 times, resulting in a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 27087.2173913
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 27087.2173913 and a remainder of 1e-08.
