We look at the division of 638666 by 24 
Let's see how many times 24 fits into 638666.

Let's proceed to step 1:
24 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 24

Going ahead to step 2:
If we divide 63 by 24, we get 2 and a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 48 from 63 to get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 24

Going ahead to step 3:
24 can be fit into 158 6 times, resulting in a remainder of 14.
The next digit of our result is 6. 
Result so far: 26.0
Deduct 144 from 158 and we're left with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 24

Moving on to step 4:
24 goes into 146 6 times with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 266.0
Subtracting 144 from 146 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 24

Moving on to step 5:
24 goes into 26 1 times with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 2661.0
The remainder is 2 after subtracting 24 from 26.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 24

Going ahead to step 6:
If we divide 26 by 24, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 26611.0
Deduct 24 from 26 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 24 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 26611.0
Subtract 0 from 20 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.

Moving on to step 8:
If we divide 200 by 24, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 26611.08
Subtracting 192 from 200 leaves us 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.

Let's proceed to step 9:
The number 24 fits into 80 3 times, leaving a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 26611.083
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.

Step 10:
If we divide 80 by 24, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 26611.0833
Subtracting 72 from 80 leaves us 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 result is 26611.0833 with a remainder of 8e-05.
