Let's divide 139668 by 2
We're looking to find how many times 2 goes into 139668.

Let's proceed to step 1:
2 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Going ahead to step 2:
2 can be fit into 13 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 12 from 13 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 2

Moving on to step 3:
2 can be fit into 19 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 69.0
The remainder is 1 after subtracting 18 from 19.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Moving on to step 4:
2 goes into 16 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 698.0
Subtract 16 from 16 to get 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Moving on to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 6983.0
If we subtract 6 from 6, we get 0.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 2

Moving on to step 6:
2 goes into 8 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 69834.0
If we subtract 8 from 8, 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.

Advancing to step 7:
0 divided by 2 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 69834.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 69834.0
Subtract 0 from 0 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.

After the division, we end up with 69834.0 and a remainder of 0.0.
