We look at the division of 868903 by 24 
The aim is to understand the frequency of 24 in 868903.

Step 1:
24 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 24

Let's proceed to step 2:
86 divided by 24 is 3 with a remainder of 14.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Deduct 72 from 86 and we're left with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 24

Going ahead to step 3:
148 divided by 24 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 4 after subtracting 144 from 148.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 24

On to step 4:
24 can be fit into 49 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 362.0
If we subtract 48 from 49, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 24

Moving on to step 5:
24 goes into 10 0 times with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 3620.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 24

Moving on to step 6:
The number 24 fits into 103 4 times, leaving a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 36204.0
The remainder is 7 after subtracting 96 from 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 24 fits into 70 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 36204.2
The remainder is 22 after subtracting 48 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
When dividing 220 by 24, we get 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 36204.29
The remainder is 4 after subtracting 216 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
The number 24 fits into 40 1 times, leaving a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 36204.291
The remainder is 16 after subtracting 24 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 10:
24 can be fit into 160 6 times, resulting in a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 36204.2916
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 24 is 6 with a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 36204.29166
Subtracting 144 from 160 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.

After the division, we end up with 36204.29166 and a remainder of 1.6e-05.
