Let's divide 855798 by 4
We're looking to find how many times 4 goes into 855798.

Step 1:
4 goes into 8 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 8 from 8, we get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 4

On to step 2:
The number 4 fits into 5 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtract 4 from 5 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 4

On to step 3:
The number 4 fits into 15 3 times, leaving a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 213.0
The remainder is 3 after subtracting 12 from 15.
Grab the next digit (7) from the dividend, add it to 3, then carry on: 37 / 4

On to step 4:
37 divided by 4 is 9 with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 2139.0
If we subtract 36 from 37, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 4

Moving on to step 5:
19 divided by 4 is 4 with a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 21394.0
If we take 16 away from 19, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 4

Advancing to step 6:
If we divide 38 by 4, we get 9 and a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 213949.0
If we subtract 36 from 38, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 4 is 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 213949.5
Subtract 20 from 20 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.

Let's proceed to step 8:
The number 4 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 213949.5
If we take 0 away from 0, we end up 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.

Going ahead to step 9:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 213949.5
Subtract 0 from 0 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.

Our division results in 213949.5 with a remaining 0.0.
