We look at the division of 501269 by 2 
Our goal is to divide 501269 by 2.

Step 1:
2 goes into 5 2 times with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 4 from 5 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Step 2:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 25.0
Subtracting 10 from 10 leaves us with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

On to step 3:
2 goes into 1 0 times with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 250.0
If we take 0 away from 1, we end up with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 2

Advancing to step 4:
12 divided by 2 is 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 2506.0
If we take 12 away from 12, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Advancing to step 5:
2 goes into 6 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 25063.0
If we subtract 6 from 6, we get 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

On to step 6:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 250634.0
Subtracting 8 from 9 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.

Step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 250634.5
If we take 10 away from 10, we end up 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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 250634.5
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.

On to step 9:
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: 250634.5
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 result is 250634.5 with a remainder of 0.0.
