We look at the division of 811300 by 3 
Let's see how many times 3 fits into 811300.

On to step 1:
3 goes into 8 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Advancing to step 2:
21 divided by 3 is 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 27.0
The remainder is 0 after subtracting 21 from 21.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 3

Let's proceed to step 3:
3 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 270.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 3

Step 4:
If we divide 13 by 3, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 2704.0
If we take 12 away from 13, we end up with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Advancing to step 5:
3 can be fit into 10 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 27043.0
Subtracting 9 from 10 leaves us with 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 3

Moving on to step 6:
10 divided by 3 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 270433.0
Deduct 9 from 10 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 270433.3
Subtracting 9 from 10 leaves us with 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 8:
The number 3 fits into 10 3 times, leaving a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 270433.33
Subtract 9 from 10 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.

Our division results in 270433.33 with a remaining 0.001.
