We look at the division of 133263 by 23 
The aim is to understand the frequency of 23 in 133263.

Advancing to step 1:
If we divide 1 by 23, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 23

Step 2:
The number 23 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 13, we end up with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 23

Step 3:
23 can be fit into 133 5 times, resulting in a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 115 from 133 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 23

Going ahead to step 4:
If we divide 182 by 23, we get 7 and a remainder of 21.
The number 7 becomes the next digit in our result. 
Result so far: 57.0
If we subtract 161 from 182, we get 21.
Bring next digit (6) of the dividend behind the 21 and repeat the process: 216 / 23

Step 5:
23 can be fit into 216 9 times, resulting in a remainder of 9.
Put 9 as the next digit of the answer. 
Result so far: 579.0
If we take 207 away from 216, we end up with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 23

Let's proceed to step 6:
When dividing 93 by 23, we get 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 5794.0
Subtracting 92 from 93 leaves us 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.

Step 7:
23 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 5794.0
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.

Advancing to step 8:
If we divide 100 by 23, we get 4 and a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 5794.04
Subtracting 92 from 100 leaves us 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.

Let's proceed to step 9:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 5794.043
Deduct 69 from 80 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 10:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 5794.0434
If we take 92 away from 110, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 11:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 5794.04347
If we take 161 away from 180, we end up 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 12:
When dividing 190 by 23, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 5794.043478
Subtracting 184 from 190 leaves us 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.

Moving on to step 13:
60 divided by 23 is 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 5794.0434782
If we take 46 away from 60, we end up 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.

Going ahead to step 14:
140 divided by 23 is 6 with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 5794.04347826
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final result is 5794.04347826 with a remainder of 2e-09.
