We look at the division of 535205 by 23 
The aim is to understand the frequency of 23 in 535205.

Moving on to step 1:
The number 23 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 23

Moving on to step 2:
When dividing 53 by 23, we get 2 with a remainder of 7.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 46 from 53 leaves us with 7.
Include the next digit (5) from the dividend after 7, then repeat: 75 / 23

Going ahead to step 3:
If we divide 75 by 23, we get 3 and a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we subtract 69 from 75, we get 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 23

Moving on to step 4:
23 can be fit into 62 2 times, resulting in a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 232.0
The remainder is 16 after subtracting 46 from 62.
Bring next digit (0) of the dividend behind the 16 and repeat the process: 160 / 23

Going ahead to step 5:
23 can be fit into 160 6 times, resulting in a remainder of 22.
Put 6 as the next digit of the answer. 
Result so far: 2326.0
If we subtract 138 from 160, we get 22.
Grab the next digit (5) from the dividend, add it to 22, then carry on: 225 / 23

Let's proceed to step 6:
23 goes into 225 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 23269.0
Subtract 207 from 225 to 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.

Moving on to step 7:
23 goes into 180 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 23269.7
Deduct 161 from 180 and we're left 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.

Let's proceed to step 8:
23 can be fit into 190 8 times, resulting in a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 23269.78
Subtract 184 from 190 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 9:
60 divided by 23 is 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 23269.782
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.

Going ahead to step 10:
If we divide 140 by 23, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 23269.7826
If we take 138 away from 140, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 11:
23 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 23269.7826
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.

Going ahead to step 12:
When dividing 200 by 23, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 23269.782608
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.

Moving on to step 13:
23 goes into 160 6 times with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 23269.7826086
If we subtract 138 from 160, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 14:
When dividing 220 by 23, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 23269.78260869
Deduct 207 from 220 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The quotient of the division is 23269.78260869, and the remainder is 1.3e-08.
