We look at the division of 424307 by 23 
The aim is to understand the frequency of 23 in 424307.

Let's proceed to step 1:
The number 23 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 23

Advancing to step 2:
42 divided by 23 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 42 to get 19.
Take the next digit (4) from the dividend and append it to 19, then repeat: 194 / 23

Advancing to step 3:
The number 23 fits into 194 8 times, leaving a remainder of 10.
The next digit of our result is 8. 
Result so far: 18.0
If we subtract 184 from 194, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 23

On to step 4:
If we divide 103 by 23, we get 4 and a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 184.0
If we take 92 away from 103, we end up with 11.
Bring next digit (0) of the dividend behind the 11 and repeat the process: 110 / 23

On to step 5:
23 can be fit into 110 4 times, resulting in a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 1844.0
Subtract 92 from 110 to get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 23

Going ahead to step 6:
23 can be fit into 187 8 times, resulting in a remainder of 3.
Put 8 as the next digit of the answer. 
Result so far: 18448.0
The remainder is 3 after subtracting 184 from 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 18448.1
Subtracting 23 from 30 leaves us 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.

Step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 18448.13
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 9:
10 divided by 23 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 18448.13
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.

Going ahead to step 10:
23 can be fit into 100 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 18448.1304
If we take 92 away from 100, we end up 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.

Going ahead to step 11:
The number 23 fits into 80 3 times, leaving a remainder of 11.
The next digit of our result is 3. 
Result so far: 18448.13043
The remainder is 11 after subtracting 69 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
23 goes into 110 4 times with a remainder of 18.
Put 4 as the next digit of the answer. 
Result so far: 18448.130434
Subtract 92 from 110 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.

Advancing to step 13:
23 can be fit into 180 7 times, resulting in a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 18448.1304347
The remainder is 19 after subtracting 161 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 14:
The number 23 fits into 190 8 times, leaving a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 18448.13043478
Deduct 184 from 190 and we're left 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.

Our division results in 18448.13043478 with a remaining 6e-09.
