We look at the division of 530123 by 2 
We want to divide 530123 by 2.

Going ahead to step 1:
2 can be fit into 5 2 times, resulting in a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 4 away from 5, we end up with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 2

Advancing to step 2:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Subtract 12 from 13 to get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Step 3:
10 divided by 2 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 265.0
If we subtract 10 from 10, we get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Moving on to step 4:
If we divide 1 by 2, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 2650.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Step 5:
If we divide 12 by 2, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 26506.0
Subtract 12 from 12 to get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 2

On to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 265061.0
Deduct 2 from 3 and we're left 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:
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: 265061.5
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:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 265061.5
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.

Going ahead to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 265061.5
The remainder is 0 after subtracting 0 from 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 265061.5 with a remainder of 0.0.
