We look at the division of 129084 by 2 
Let's see how many times 2 fits into 129084.

On to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

On to step 2:
2 can be fit into 12 6 times, resulting in a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 12 away from 12, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 2

Step 3:
When dividing 9 by 2, we get 4 with a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 64.0
If we subtract 8 from 9, we get 1.
Take the next digit (0) from the dividend and append it to 1, then repeat: 10 / 2

On to step 4:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 645.0
Deduct 10 from 10 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Going ahead to step 5:
If we divide 8 by 2, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 6454.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Moving on to step 6:
If we divide 4 by 2, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 64542.0
Subtract 4 from 4 to 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.

Step 7:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 64542.0
If we take 0 away from 0, 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.

Let's proceed 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: 64542.0
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.

In conclusion, the division gives 64542.0 with a balance of 0.0.
