We look at the division of 811997 by 3 
We want to figure out the number of times 811997 can be divided by 3.

Going ahead to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 6 from 8 and we're left with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 3

Moving on to step 2:
When dividing 21 by 3, we get 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 27.0
Subtract 21 from 21 to get 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 3

Step 3:
When dividing 1 by 3, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 270.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 3

On to step 4:
If we divide 19 by 3, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 2706.0
If we take 18 away from 19, we end up with 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 3

Moving on to step 5:
When dividing 19 by 3, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 27066.0
If we subtract 18 from 19, we get 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 3

Step 6:
3 goes into 17 5 times with a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 270665.0
Subtract 15 from 17 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.

Step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 270665.6
If we subtract 18 from 20, 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.

Moving on to step 8:
3 can be fit into 20 6 times, resulting in a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 270665.66
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.

Our division results in 270665.66 with a remaining 0.002.
