We look at the division of 705396 by 23 
The aim is to understand the frequency of 23 in 705396.

On to step 1:
If we divide 7 by 23, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 23

Going ahead to step 2:
The number 23 fits into 70 3 times, leaving a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 69 from 70, we get 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 23

Let's proceed to step 3:
If we divide 15 by 23, we get 0 and a remainder of 15.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 15 after subtracting 0 from 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 23

Going ahead to step 4:
If we divide 153 by 23, we get 6 and a remainder of 15.
Use 6 as the next digit of our solution. 
Result so far: 306.0
Subtract 138 from 153 to get 15.
Include the next digit (9) from the dividend after 15, then repeat: 159 / 23

On to step 5:
23 can be fit into 159 6 times, resulting in a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 3066.0
If we subtract 138 from 159, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 23

Advancing to step 6:
If we divide 216 by 23, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 30669.0
Deduct 207 from 216 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.

Let's proceed to step 7:
23 goes into 90 3 times with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 30669.3
If we take 69 away from 90, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 8:
When dividing 210 by 23, we get 9 with a remainder of 3.
Write down 9 as next digit of the result. 
Result so far: 30669.39
Subtract 207 from 210 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
When dividing 30 by 23, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 30669.391
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
When dividing 70 by 23, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 30669.3913
Subtracting 69 from 70 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.

Let's proceed to step 11:
23 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 30669.3913
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 23, we get 4 and a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 30669.391304
The remainder is 8 after subtracting 92 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
23 can be fit into 80 3 times, resulting in a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 30669.3913043
If we subtract 69 from 80, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 14:
110 divided by 23 is 4 with a remainder of 18.
The next digit of our result is 4. 
Result so far: 30669.39130434
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.

The final outcome is 30669.39130434, with a leftover of 1.8e-08.
