We divide 129455 by 2
Let's see how many times 2 fits into 129455.

Let's proceed to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 2

Let's proceed to step 2:
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: 6.0
Deduct 12 from 12 and we're left with 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

Moving on to step 3:
9 divided by 2 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 64.0
If we take 8 away from 9, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Advancing to step 4:
If we divide 14 by 2, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 647.0
Subtracting 14 from 14 leaves us with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 2

Going ahead to step 5:
5 divided by 2 is 2 with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 6472.0
Subtract 4 from 5 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Let's proceed to step 6:
If we divide 15 by 2, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 64727.0
If we take 14 away from 15, we end up 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.

On to step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 64727.5
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.

Going ahead to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 64727.5
Deduct 0 from 0 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 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 64727.5
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 64727.5, with a leftover of 0.0.
