We're dividing 28417 by 23 
The aim is to understand the frequency of 23 in 28417.

Moving on to step 1:
23 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 23

Moving on to step 2:
23 goes into 28 1 times with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 23 from 28 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 23

Step 3:
54 divided by 23 is 2 with a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Subtract 46 from 54 to get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 23

Advancing to step 4:
If we divide 81 by 23, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 123.0
Subtracting 69 from 81 leaves us with 12.
Fetch the next digit (7) from the dividend, attach it to 12 and continue: 127 / 23

Advancing to step 5:
23 goes into 127 5 times with a remainder of 12.
Record the quotient 5 as the next digit in the result. 
Result so far: 1235.0
If we take 115 away from 127, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 6:
When dividing 120 by 23, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1235.5
Subtracting 115 from 120 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 7:
When dividing 50 by 23, we get 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 1235.52
If we take 46 away from 50, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 8:
The number 23 fits into 40 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1235.521
Subtracting 23 from 40 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 9:
The number 23 fits into 170 7 times, leaving a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 1235.5217
If we subtract 161 from 170, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 10:
23 goes into 90 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 1235.52173
Deduct 69 from 90 and we're left 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.

Moving on to step 11:
23 goes into 210 9 times with a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1235.521739
If we take 207 away from 210, 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.

Moving on to step 12:
30 divided by 23 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 1235.5217391
If we take 23 away from 30, we end up 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.

On to step 13:
70 divided by 23 is 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1235.52173913
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.

After the division, we end up with 1235.52173913 and a remainder of 1e-09.
