811285 ÷ 4 
We want to figure out the number of times 811285 can be divided by 4.

Step 1:
The number 4 fits into 8 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 0 after subtracting 8 from 8.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

On to step 2:
The number 4 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 20.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 4

Step 3:
When dividing 11 by 4, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 202.0
If we take 8 away from 11, we end up with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 4

Moving on to step 4:
4 can be fit into 32 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 2028.0
If we subtract 32 from 32, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

On to step 5:
The number 4 fits into 8 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 20282.0
The remainder is 0 after subtracting 8 from 8.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 4

On to step 6:
When dividing 5 by 4, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 202821.0
Subtract 4 from 5 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
4 can be fit into 10 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 202821.2
The remainder is 2 after subtracting 8 from 10.
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 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 202821.25
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.

Going ahead to step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 202821.25
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.

Let's proceed to step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 202821.25
Deduct 0 from 0 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.

In conclusion, the division gives 202821.25 with a balance of 0.0.
