Let's divide 509269 by 23
The aim is to understand the frequency of 23 in 509269.

Advancing to step 1:
When dividing 5 by 23, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 23

Let's proceed to step 2:
50 divided by 23 is 2 with a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 46 from 50 leaves us with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 23

Let's proceed to step 3:
If we divide 49 by 23, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 22.0
Subtract 46 from 49 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 23

Step 4:
When dividing 32 by 23, we get 1 with a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 221.0
If we take 23 away from 32, we end up with 9.
Bring next digit (6) of the dividend behind the 9 and repeat the process: 96 / 23

On to step 5:
23 can be fit into 96 4 times, resulting in a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 2214.0
If we take 92 away from 96, we end up with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 23

Moving on to step 6:
23 can be fit into 49 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 22142.0
If we take 46 away from 49, we end up 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.

On 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: 22142.1
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.

On to step 8:
If we divide 70 by 23, we get 3 and a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 22142.13
If we take 69 away from 70, we end up 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.

Advancing to step 9:
23 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 22142.13
The remainder is 10 after subtracting 0 from 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 10:
The number 23 fits into 100 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 22142.1304
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.

On to step 11:
23 goes into 80 3 times with a remainder of 11.
The next digit of our result is 3. 
Result so far: 22142.13043
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.

Let's proceed to step 12:
If we divide 110 by 23, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 22142.130434
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.

Step 13:
When dividing 180 by 23, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 22142.1304347
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.

On to step 14:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 22142.13043478
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.

The final result is 22142.13043478 with a remainder of 6e-09.
