252539 divided by 2 
Our goal is to divide 252539 by 2.

Moving on to step 1:
2 goes into 2 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 2 from 2 to get 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Let's proceed to step 2:
If we divide 5 by 2, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
The remainder is 1 after subtracting 4 from 5.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Going ahead to step 3:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 126.0
Subtract 12 from 12 to get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 2

Let's proceed to step 4:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 1262.0
If we take 4 away from 5, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

On to step 5:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 12626.0
Subtract 12 from 13 to get 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 2

Advancing to step 6:
If we divide 19 by 2, we get 9 and a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 126269.0
Deduct 18 from 19 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.

Let's proceed to step 7:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 126269.5
Subtracting 10 from 10 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 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 126269.5
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.

Let's proceed to step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 126269.5
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.

The final outcome is 126269.5, with a leftover of 0.0.
