We're dividing 139046 by 2 
We want to divide 139046 by 2.

Step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 2

On to step 2:
If we divide 13 by 2, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 12 from 13 and we're left with 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 2

On to step 3:
If we divide 19 by 2, we get 9 and a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we subtract 18 from 19, we get 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Step 4:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 695.0
Subtract 10 from 10 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 2

Moving on to step 5:
The number 2 fits into 4 2 times, leaving a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 6952.0
Subtract 4 from 4 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 2

Step 6:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 69523.0
Subtracting 6 from 6 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 7:
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: 69523.0
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.

Moving on to step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 69523.0
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.

The final result is 69523.0 with a remainder of 0.0.
