We divide 52866 by 2
We're looking to find how many times 2 goes into 52866.

Step 1:
5 divided by 2 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 4 from 5 to get 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 2

Advancing to step 2:
The number 2 fits into 12 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 26.0
Subtract 12 from 12 to get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 2

Step 3:
8 divided by 2 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 264.0
Subtracting 8 from 8 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Going ahead to step 4:
2 goes into 6 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 2643.0
If we take 6 away from 6, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

Moving on to step 5:
2 can be fit into 6 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 26433.0
Subtract 6 from 6 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.

Moving on to step 6:
If we divide 0 by 2, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26433.0
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.

Let's proceed to step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 26433.0
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 outcome is 26433.0, with a leftover of 0.0.
