We're dividing 498657 by 24 
We want to divide 498657 by 24.

Step 1:
4 divided by 24 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 24

Going ahead to step 2:
The number 24 fits into 49 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 48 from 49 to get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 24

Going ahead to step 3:
If we divide 18 by 24, we get 0 and a remainder of 18.
The next digit of our result is 0. 
Result so far: 20.0
Subtract 0 from 18 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 24

Going ahead to step 4:
The number 24 fits into 186 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 207.0
If we take 168 away from 186, we end up with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 24

Going ahead to step 5:
The number 24 fits into 185 7 times, leaving a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2077.0
Deduct 168 from 185 and we're left with 17.
Fetch the next digit (7) from the dividend, attach it to 17 and continue: 177 / 24

Advancing to step 6:
If we divide 177 by 24, we get 7 and a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 20777.0
If we subtract 168 from 177, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 24, we get 3 and a remainder of 18.
The next digit of our result is 3. 
Result so far: 20777.3
If we subtract 72 from 90, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 8:
The number 24 fits into 180 7 times, leaving a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 20777.37
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 9:
24 goes into 120 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 20777.375
Subtract 120 from 120 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
24 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20777.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
24 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20777.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 20777.375 with a remainder of 0.0.
