Let's divide 865819 by 4
Let's see how many times 4 fits into 865819.

On to step 1:
If we divide 8 by 4, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 4

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
Subtracting 4 from 6 leaves us with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 4

On to step 3:
The number 4 fits into 25 6 times, leaving a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 216.0
The remainder is 1 after subtracting 24 from 25.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Moving on to step 4:
When dividing 18 by 4, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 2164.0
Subtracting 16 from 18 leaves us with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 4

Step 5:
The number 4 fits into 21 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 21645.0
If we subtract 20 from 21, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Let's proceed to step 6:
The number 4 fits into 19 4 times, leaving a remainder of 3.
Put 4 as the next digit of the answer. 
Result so far: 216454.0
Subtracting 16 from 19 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
4 goes into 30 7 times with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 216454.7
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.

Moving on to step 8:
4 goes into 20 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 216454.75
Deduct 20 from 20 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.

Let's proceed 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: 216454.75
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.

On to step 10:
4 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 216454.75
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.

Our division results in 216454.75 with a remaining 0.0.
