We're dividing 366919 by 23 
The aim is to understand the frequency of 23 in 366919.

Moving on to step 1:
The number 23 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 23

Moving on to step 2:
If we divide 36 by 23, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 23 from 36 to get 13.
Append the next digit (6) from the dividend to 13 and continue with: 136 / 23

On to step 3:
23 can be fit into 136 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we subtract 115 from 136, we get 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 23

Advancing to step 4:
If we divide 219 by 23, we get 9 and a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 159.0
The remainder is 12 after subtracting 207 from 219.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 23

Step 5:
23 can be fit into 121 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 1595.0
If we subtract 115 from 121, we get 6.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 23

Advancing to step 6:
The number 23 fits into 69 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 15953.0
The remainder is 0 after subtracting 69 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
0 divided by 23 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15953.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
When dividing 0 by 23, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15953.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 15953.0 with a balance of 0.0.
