We look at the division of 30499 by 23 
The aim is to understand the frequency of 23 in 30499.

Step 1:
If we divide 3 by 23, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 23

Moving on to step 2:
30 divided by 23 is 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 7 after subtracting 23 from 30.
Append the next digit (4) from the dividend to 7 and continue with: 74 / 23

Step 3:
If we divide 74 by 23, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 69 from 74 and we're left with 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 23

Going ahead to step 4:
23 can be fit into 59 2 times, resulting in a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 132.0
Subtracting 46 from 59 leaves us with 13.
Include the next digit (9) from the dividend after 13, then repeat: 139 / 23

Advancing to step 5:
23 can be fit into 139 6 times, resulting in a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1326.0
If we subtract 138 from 139, 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 6:
If we divide 10 by 23, we get 0 and a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 1326.0
Subtracting 0 from 10 leaves us 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 7:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1326.04
If we take 92 away from 100, we end up 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.

Moving on to step 8:
The number 23 fits into 80 3 times, leaving a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 1326.043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 9:
110 divided by 23 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 1326.0434
If we subtract 92 from 110, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
If we divide 180 by 23, we get 7 and a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 1326.04347
Subtracting 161 from 180 leaves us with 19.
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 11:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1326.043478
The remainder is 6 after subtracting 184 from 190.
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 12:
When dividing 60 by 23, we get 2 with a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1326.0434782
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.

Let's proceed to step 13:
23 goes into 140 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 1326.04347826
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.

After the division, we end up with 1326.04347826 and a remainder of 2e-09.
