79666 ÷ 2 
We want to divide 79666 by 2.

Going ahead to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 6 away from 7, we end up with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 2

Step 2:
2 can be fit into 19 9 times, resulting in a remainder of 1.
The next digit of our result is 9. 
Result so far: 39.0
If we subtract 18 from 19, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 2

On to step 3:
16 divided by 2 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 398.0
The remainder is 0 after subtracting 16 from 16.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Let's proceed to step 4:
When dividing 6 by 2, we get 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 3983.0
The remainder is 0 after subtracting 6 from 6.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

On to step 5:
If we divide 6 by 2, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 39833.0
The remainder is 0 after subtracting 6 from 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 6:
When dividing 0 by 2, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39833.0
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.

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: 39833.0
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.

The final result is 39833.0 with a remainder of 0.0.
