939458 ÷ 23 
The aim is to understand the frequency of 23 in 939458.

Let's proceed to step 1:
If we divide 9 by 23, we get 0 and a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 23

Moving on to step 2:
If we divide 93 by 23, we get 4 and a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 92 from 93 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 23

On to step 3:
23 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 40.0
The remainder is 19 after subtracting 0 from 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 23

Moving on to step 4:
23 can be fit into 194 8 times, resulting in a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 408.0
If we take 184 away from 194, we end up with 10.
Grab the next digit (5) from the dividend, add it to 10, then carry on: 105 / 23

Moving on to step 5:
If we divide 105 by 23, we get 4 and a remainder of 13.
Write down 4 as next digit of the result. 
Result so far: 4084.0
Subtract 92 from 105 to get 13.
Include the next digit (8) from the dividend after 13, then repeat: 138 / 23

Step 6:
23 can be fit into 138 6 times, resulting in a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 40846.0
Subtracting 138 from 138 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.

On to step 7:
0 divided by 23 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 40846.0
If we take 0 away from 0, we end up 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.

On to step 8:
If we divide 0 by 23, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 40846.0
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.

The quotient of the division is 40846.0, and the remainder is 0.0.
