We look at the division of 333033 by 23 
The aim is to understand the frequency of 23 in 333033.

On to step 1:
The number 23 fits into 3 0 times, leaving 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.
Take the next digit (3) from the dividend and append it to 3, then repeat: 33 / 23

On to step 2:
When dividing 33 by 23, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 23 from 33 and we're left with 10.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 23

Let's proceed to step 3:
When dividing 103 by 23, we get 4 with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 14.0
Subtract 92 from 103 to get 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 23

Step 4:
The number 23 fits into 110 4 times, leaving a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 144.0
Deduct 92 from 110 and we're left with 18.
Bring next digit (3) of the dividend behind the 18 and repeat the process: 183 / 23

On to step 5:
183 divided by 23 is 7 with a remainder of 22.
Write down 7 as next digit of the result. 
Result so far: 1447.0
The remainder is 22 after subtracting 161 from 183.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 23

On to step 6:
If we divide 223 by 23, we get 9 and a remainder of 16.
The number 9 becomes the next digit in our result. 
Result so far: 14479.0
The remainder is 16 after subtracting 207 from 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
The number 23 fits into 160 6 times, leaving a remainder of 22.
Write down 6 as next digit of the result. 
Result so far: 14479.6
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.

Moving on to step 8:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 14479.69
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.

Step 9:
23 can be fit into 130 5 times, resulting in a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 14479.695
If we take 115 away from 130, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 10:
150 divided by 23 is 6 with a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 14479.6956
If we subtract 138 from 150, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 23 fits into 120 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 14479.69565
The remainder is 5 after subtracting 115 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 12:
50 divided by 23 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 14479.695652
Deduct 46 from 50 and we're left 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 13:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 14479.6956521
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 14:
If we divide 170 by 23, we get 7 and a remainder of 9.
Record the quotient 7 as the next digit in the result. 
Result so far: 14479.69565217
Deduct 161 from 170 and we're left 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.

The final outcome is 14479.69565217, with a leftover of 9e-09.
