We look at the division of 815803 by 24 
The aim is to understand the frequency of 24 in 815803.

Moving on to step 1:
24 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 24

Moving on to step 2:
24 can be fit into 81 3 times, resulting in a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 9 after subtracting 72 from 81.
Bring next digit (5) of the dividend behind the 9 and repeat the process: 95 / 24

On to step 3:
If we divide 95 by 24, we get 3 and a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 33.0
Deduct 72 from 95 and we're left with 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 24

Advancing to step 4:
When dividing 238 by 24, we get 9 with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 339.0
Subtracting 216 from 238 leaves us with 22.
Take the next digit (0) from the dividend and append it to 22, then repeat: 220 / 24

Moving on to step 5:
The number 24 fits into 220 9 times, leaving a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 3399.0
If we take 216 away from 220, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 24

Let's proceed to step 6:
When dividing 43 by 24, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 33991.0
Subtracting 24 from 43 leaves us with 19.
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:
The number 24 fits into 190 7 times, leaving a remainder of 22.
Put 7 as the next digit of the answer. 
Result so far: 33991.7
The remainder is 22 after subtracting 168 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 8:
When dividing 220 by 24, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 33991.79
If we subtract 216 from 220, we get 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 9:
40 divided by 24 is 1 with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 33991.791
Subtract 24 from 40 to get 16.
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: 33991.7916
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.

Let's proceed to step 11:
When dividing 160 by 24, we get 6 with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 33991.79166
If we subtract 144 from 160, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 33991.79166 with a remaining 1.6e-05.
