We're dividing 811757 by 3 
Let's see how many times 3 fits into 811757.

Step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 2 after subtracting 6 from 8.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 3

On to step 2:
21 divided by 3 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
The remainder is 0 after subtracting 21 from 21.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Going ahead to step 3:
The number 3 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 270.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 3

Advancing to step 4:
17 divided by 3 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 2705.0
Subtracting 15 from 17 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Moving on to step 5:
25 divided by 3 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 27058.0
If we take 24 away from 25, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Moving on to step 6:
17 divided by 3 is 5 with a remainder of 2.
The next digit of our result is 5. 
Result so far: 270585.0
Deduct 15 from 17 and we're left 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.

Step 7:
When dividing 20 by 3, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 270585.6
Deduct 18 from 20 and we're left 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.

Advancing to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
The next digit of our result is 6. 
Result so far: 270585.66
Subtract 18 from 20 to 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.

After the division, we end up with 270585.66 and a remainder of 0.002.
