We're dividing 495831 by 2 
We want to divide 495831 by 2.

Moving on to step 1:
The number 2 fits into 4 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Advancing to step 2:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 24.0
If we subtract 8 from 9, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

On to step 3:
15 divided by 2 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 247.0
Subtracting 14 from 15 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Step 4:
2 goes into 18 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 2479.0
If we subtract 18 from 18, we get 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 2

On to step 5:
2 can be fit into 3 1 times, resulting in a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 24791.0
Subtract 2 from 3 to get 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 2

Moving on to step 6:
If we divide 11 by 2, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 247915.0
Subtracting 10 from 11 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 247915.5
Deduct 10 from 10 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 247915.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 247915.5
If we subtract 0 from 0, we 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 outcome is 247915.5, with a leftover of 0.0.
