393803 ÷ 24 
The aim is to understand the frequency of 24 in 393803.

Step 1:
3 divided by 24 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 24

Step 2:
39 divided by 24 is 1 with a remainder of 15.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 24 away from 39, we end up with 15.
Grab the next digit (3) from the dividend, add it to 15, then carry on: 153 / 24

Advancing to step 3:
The number 24 fits into 153 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
The remainder is 9 after subtracting 144 from 153.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 24

On to step 4:
When dividing 98 by 24, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 164.0
Subtract 96 from 98 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 24

Step 5:
If we divide 20 by 24, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1640.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 24

Advancing to step 6:
If we divide 203 by 24, we get 8 and a remainder of 11.
Write down 8 as next digit of the result. 
Result so far: 16408.0
Subtracting 192 from 203 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
110 divided by 24 is 4 with a remainder of 14.
The next digit of our result is 4. 
Result so far: 16408.4
If we take 96 away from 110, we end up 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.

Let's proceed to step 8:
24 goes into 140 5 times with a remainder of 20.
The next digit of our result is 5. 
Result so far: 16408.45
Deduct 120 from 140 and we're left 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.

Moving on to step 9:
200 divided by 24 is 8 with a remainder of 8.
The next digit of our result is 8. 
Result so far: 16408.458
If we take 192 away from 200, 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.

Going ahead to step 10:
The number 24 fits into 80 3 times, leaving a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 16408.4583
If we subtract 72 from 80, 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 11:
24 goes into 80 3 times with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 16408.45833
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 16408.45833 and a remainder of 8e-06.
