We look at the division of 786115 by 23 
The aim is to understand the frequency of 23 in 786115.

On to step 1:
7 divided by 23 is 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 23

Moving on to step 2:
78 divided by 23 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 9 after subtracting 69 from 78.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 23

Going ahead to step 3:
When dividing 96 by 23, we get 4 with a remainder of 4.
Write down 4 as next digit of the result. 
Result so far: 34.0
If we subtract 92 from 96, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 23

On to step 4:
41 divided by 23 is 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 341.0
Deduct 23 from 41 and we're left with 18.
Fetch the next digit (1) from the dividend, attach it to 18 and continue: 181 / 23

On to step 5:
181 divided by 23 is 7 with a remainder of 20.
The next digit of our result is 7. 
Result so far: 3417.0
The remainder is 20 after subtracting 161 from 181.
Bring next digit (5) of the dividend behind the 20 and repeat the process: 205 / 23

Step 6:
23 goes into 205 8 times with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 34178.0
Subtract 184 from 205 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
210 divided by 23 is 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 34178.9
Subtracting 207 from 210 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
The number 23 fits into 30 1 times, leaving a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 34178.91
If we take 23 away from 30, we end up with 7.
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 9:
When dividing 70 by 23, we get 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 34178.913
If we subtract 69 from 70, 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.

Moving on to step 10:
10 divided by 23 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 34178.913
Subtract 0 from 10 to 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.

Moving on to step 11:
The number 23 fits into 100 4 times, leaving a remainder of 8.
The next digit of our result is 4. 
Result so far: 34178.91304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 12:
23 goes into 80 3 times with a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 34178.913043
If we take 69 away from 80, we end up 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.

Let's proceed to step 13:
110 divided by 23 is 4 with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 34178.9130434
Subtracting 92 from 110 leaves us 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.

Moving on to step 14:
The number 23 fits into 180 7 times, leaving a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 34178.91304347
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.

After the division, we end up with 34178.91304347 and a remainder of 1.9e-08.
