139948 divided by 2 
Let's see how many times 2 fits into 139948.

Moving on to step 1:
When dividing 1 by 2, we get 0 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.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Moving on to step 2:
2 goes into 13 6 times with a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 12 from 13 to get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 2

Let's proceed to step 3:
If we divide 19 by 2, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 69.0
Subtracting 18 from 19 leaves us with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Step 4:
19 divided by 2 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 699.0
If we subtract 18 from 19, we get 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Step 5:
14 divided by 2 is 7 with a remainder of 0.
The next digit of our result is 7. 
Result so far: 6997.0
Deduct 14 from 14 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Let's proceed to step 6:
The number 2 fits into 8 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 69974.0
The remainder is 0 after subtracting 8 from 8.
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.
The number 0 becomes the next digit in our result. 
Result so far: 69974.0
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.

Going ahead to step 8:
2 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 69974.0
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.

The final outcome is 69974.0, with a leftover of 0.0.
