We look at the division of 78961 by 2 
We want to figure out the number of times 78961 can be divided by 2.

Going ahead to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 6 from 7 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 2:
2 goes into 18 9 times with a remainder of 0.
The next digit of our result is 9. 
Result so far: 39.0
If we take 18 away from 18, we end up with 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 2

Step 3:
2 goes into 9 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 394.0
If we take 8 away from 9, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 2

Step 4:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 3948.0
Subtract 16 from 16 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 2

On to step 5:
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: 39480.0
If we subtract 0 from 1, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 6:
When dividing 10 by 2, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 39480.5
The remainder is 0 after subtracting 10 from 10.
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 7:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 39480.5
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:
2 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39480.5
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.

The final result is 39480.5 with a remainder of 0.0.
