5286 ÷ 23 
The aim is to understand the frequency of 23 in 5286.

On to step 1:
When dividing 5 by 23, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 23

Going ahead to step 2:
23 goes into 52 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 6 after subtracting 46 from 52.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 23

Advancing to step 3:
23 can be fit into 68 2 times, resulting in a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
If we subtract 46 from 68, we get 22.
Bring next digit (6) of the dividend behind the 22 and repeat the process: 226 / 23

Step 4:
23 can be fit into 226 9 times, resulting in a remainder of 19.
Use 9 as the next digit of our solution. 
Result so far: 229.0
Subtract 207 from 226 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 5:
The number 23 fits into 190 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 229.8
Subtracting 184 from 190 leaves us 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.

Moving on to step 6:
23 goes into 60 2 times with a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 229.82
Subtract 46 from 60 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 7:
23 goes into 140 6 times with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 229.826
Subtracting 138 from 140 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
When dividing 20 by 23, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 229.826
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 9:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 229.82608
If we take 184 away from 200, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 23 is 6 with a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 229.826086
Deduct 138 from 160 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 23 fits into 220 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 229.8260869
Subtract 207 from 220 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
When dividing 130 by 23, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 229.82608695
Subtract 115 from 130 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 229.82608695 and a remainder of 1.5e-08.
