We look at the division of 496309 by 48 
Let's see how many times 48 fits into 496309.

Advancing to step 1:
The number 48 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 48

On to step 2:
48 can be fit into 49 1 times, resulting in a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 48 from 49 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 48

Moving on to step 3:
48 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 16 to get 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 48

Going ahead to step 4:
When dividing 163 by 48, we get 3 with a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we take 144 away from 163, we end up with 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 48

Step 5:
If we divide 190 by 48, we get 3 and a remainder of 46.
The next digit of our result is 3. 
Result so far: 1033.0
If we subtract 144 from 190, we get 46.
Take the next digit (9) from the dividend and append it to 46, then repeat: 469 / 48

On to step 6:
469 divided by 48 is 9 with a remainder of 37.
Put 9 as the next digit of the answer. 
Result so far: 10339.0
Subtracting 432 from 469 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
When dividing 370 by 48, we get 7 with a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 10339.7
If we subtract 336 from 370, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 48 is 7 with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 10339.77
The remainder is 4 after subtracting 336 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 10339.77, with a leftover of 0.004.
