824868 divided by 23 
The aim is to understand the frequency of 23 in 824868.

Step 1:
If we divide 8 by 23, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 23

Step 2:
If we divide 82 by 23, we get 3 and a remainder of 13.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 69 from 82 and we're left with 13.
Fetch the next digit (4) from the dividend, attach it to 13 and continue: 134 / 23

Step 3:
If we divide 134 by 23, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 35.0
Subtracting 115 from 134 leaves us with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 23

Moving on to step 4:
198 divided by 23 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 358.0
Subtract 184 from 198 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 23

Moving on to step 5:
146 divided by 23 is 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3586.0
The remainder is 8 after subtracting 138 from 146.
Take the next digit (8) from the dividend and append it to 8, then repeat: 88 / 23

Going ahead to step 6:
23 can be fit into 88 3 times, resulting in a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 35863.0
The remainder is 19 after subtracting 69 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 7:
If we divide 190 by 23, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 35863.8
If we take 184 away from 190, we end up 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.

On to step 8:
If we divide 60 by 23, we get 2 and a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 35863.82
If we subtract 46 from 60, we 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.

Advancing to step 9:
23 can be fit into 140 6 times, resulting in a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 35863.826
Subtract 138 from 140 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
20 divided by 23 is 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 35863.826
If we subtract 0 from 20, we get 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 11:
The number 23 fits into 200 8 times, leaving a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 35863.82608
Subtracting 184 from 200 leaves us 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.

Let's proceed to step 12:
23 goes into 160 6 times with a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 35863.826086
The remainder is 22 after subtracting 138 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
When dividing 220 by 23, we get 9 with a remainder of 13.
The next digit of our result is 9. 
Result so far: 35863.8260869
If we subtract 207 from 220, we 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.

Moving on to step 14:
130 divided by 23 is 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 35863.82608695
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 35863.82608695 and a remainder of 1.5e-08.
