We're dividing 861863 by 4 
Our goal is to divide 861863 by 4.

Moving on to step 1:
4 goes into 8 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 4

Moving on to step 2:
6 divided by 4 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 21.0
The remainder is 2 after subtracting 4 from 6.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 4

Step 3:
21 divided by 4 is 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 215.0
The remainder is 1 after subtracting 20 from 21.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 4

On to step 4:
4 can be fit into 18 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2154.0
Subtracting 16 from 18 leaves us with 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 4

Going ahead to step 5:
4 goes into 26 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 21546.0
Deduct 24 from 26 and we're left with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 4

Advancing to step 6:
23 divided by 4 is 5 with a remainder of 3.
Record the quotient 5 as the next digit in the result. 
Result so far: 215465.0
The remainder is 3 after subtracting 20 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
If we divide 30 by 4, we get 7 and a remainder of 2.
The next digit of our result is 7. 
Result so far: 215465.7
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
4 can be fit into 20 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 215465.75
If we subtract 20 from 20, 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 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 215465.75
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 10:
The number 4 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 215465.75
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.

In conclusion, the division gives 215465.75 with a balance of 0.0.
