We look at the division of 435863 by 24 
The aim is to understand the frequency of 24 in 435863.

Step 1:
The number 24 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 24

Advancing to step 2:
43 divided by 24 is 1 with a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 24 from 43 leaves us with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 24

Let's proceed to step 3:
The number 24 fits into 195 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 18.0
If we take 192 away from 195, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 24

On to step 4:
24 goes into 38 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 181.0
If we subtract 24 from 38, we get 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 24

Going ahead to step 5:
146 divided by 24 is 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 1816.0
Deduct 144 from 146 and we're left with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 24

Moving on to step 6:
24 goes into 23 0 times with a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 18160.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 7:
230 divided by 24 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 18160.9
Deduct 216 from 230 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 8:
When dividing 140 by 24, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 18160.95
Subtract 120 from 140 to 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.

Step 9:
200 divided by 24 is 8 with a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 18160.958
If we subtract 192 from 200, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 18160.9583
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 11:
24 can be fit into 80 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 18160.95833
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 18160.95833, with a leftover of 8e-06.
