Let's divide 343 by 23
The aim is to understand the frequency of 23 in 343.

Moving on to step 1:
3 divided by 23 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 23

Let's proceed to step 2:
34 divided by 23 is 1 with a remainder of 11.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 23 from 34, we get 11.
Take the next digit (3) from the dividend and append it to 11, then repeat: 113 / 23

Advancing to step 3:
113 divided by 23 is 4 with a remainder of 21.
The next digit of our result is 4. 
Result so far: 14.0
Subtracting 92 from 113 leaves us 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.

Step 4:
When dividing 210 by 23, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 14.9
If we subtract 207 from 210, we 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.

Let's proceed to step 5:
23 can be fit into 30 1 times, resulting in a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 14.91
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.

Let's proceed to step 6:
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: 14.913
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.

On to step 7:
When dividing 10 by 23, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 14.913
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.

Going ahead to step 8:
23 goes into 100 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 14.91304
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 9:
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: 14.913043
Subtracting 69 from 80 leaves us 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 10:
23 goes into 110 4 times with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 14.9130434
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.

On to step 11:
23 goes into 180 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 14.91304347
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.

After the division, we end up with 14.91304347 and a remainder of 1.9e-08.
