We divide 127878 by 2
We want to divide 127878 by 2.

Going ahead to step 1:
1 divided by 2 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 2

Advancing to step 2:
When dividing 12 by 2, we get 6 with a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 12 from 12 to get 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Moving on to step 3:
If we divide 7 by 2, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 63.0
The remainder is 1 after subtracting 6 from 7.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Moving on to step 4:
The number 2 fits into 18 9 times, leaving a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 639.0
If we take 18 away from 18, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 2

Step 5:
If we divide 7 by 2, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 6393.0
The remainder is 1 after subtracting 6 from 7.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 2

On to step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 63939.0
Subtracting 18 from 18 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 7:
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: 63939.0
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 63939.0
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 63939.0 with a remainder of 0.0.
