We look at the division of 866784 by 4 
Let's see how many times 4 fits into 866784.

Going ahead to step 1:
When dividing 8 by 4, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 8 from 8 and we're left with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 4

Advancing to step 2:
4 goes into 6 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 21.0
If we subtract 4 from 6, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Let's proceed to step 3:
If we divide 26 by 4, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 216.0
If we take 24 away from 26, we end up with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 4

Advancing to step 4:
The number 4 fits into 27 6 times, leaving a remainder of 3.
The next digit of our result is 6. 
Result so far: 2166.0
Subtracting 24 from 27 leaves us with 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 4

Step 5:
4 goes into 38 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 21669.0
The remainder is 2 after subtracting 36 from 38.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 4

Going ahead to step 6:
4 can be fit into 24 6 times, resulting in a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 216696.0
Deduct 24 from 24 and we're left 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.

Step 7:
4 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 216696.0
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 8:
0 divided by 4 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 216696.0
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.

After the division, we end up with 216696.0 and a remainder of 0.0.
