We look at the division of 36576045 by 23 
The aim is to understand the frequency of 23 in 36576045.

Let's proceed to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 23

Let's proceed to step 2:
When dividing 36 by 23, we get 1 with a remainder of 13.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 23 from 36, we get 13.
Bring next digit (5) of the dividend behind the 13 and repeat the process: 135 / 23

Moving on to step 3:
If we divide 135 by 23, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Deduct 115 from 135 and we're left with 20.
Include the next digit (7) from the dividend after 20, then repeat: 207 / 23

Moving on to step 4:
23 can be fit into 207 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 159.0
If we subtract 207 from 207, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 23

Let's proceed to step 5:
23 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1590.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (0) of the dividend behind the 6 and repeat the process: 60 / 23

Moving on to step 6:
60 divided by 23 is 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 15902.0
Deduct 46 from 60 and we're left with 14.
Grab the next digit (4) from the dividend, add it to 14, then carry on: 144 / 23

Step 7:
The number 23 fits into 144 6 times, leaving a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 159026.0
Deduct 138 from 144 and we're left with 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 23

Moving on to step 8:
The number 23 fits into 65 2 times, leaving a remainder of 19.
The number 2 becomes the next digit in our result. 
Result so far: 1590262.0
The remainder is 19 after subtracting 46 from 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
23 goes into 190 8 times with a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 1590262.8
If we take 184 away from 190, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 23 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 1590262.82
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 11:
23 goes into 140 6 times with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1590262.826
Subtract 138 from 140 to get 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 12:
If we divide 20 by 23, we get 0 and a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1590262.826
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 13:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1590262.82608
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.

Let's proceed to step 14:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 1590262.826086
Subtracting 138 from 160 leaves us 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.

Step 15:
220 divided by 23 is 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 1590262.8260869
Subtract 207 from 220 to 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 16:
The number 23 fits into 130 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 1590262.82608695
If we subtract 115 from 130, we 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.

After the division, we end up with 1590262.82608695 and a remainder of 1.5e-08.
