We look at the division of 816955 by 3 
We want to divide 816955 by 3.

Step 1:
When dividing 8 by 3, we get 2 with 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

Going ahead to step 2:
If we divide 21 by 3, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 27.0
If we take 21 away from 21, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 3

Going ahead to step 3:
When dividing 6 by 3, we get 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 272.0
If we subtract 6 from 6, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 3

Moving on to step 4:
If we divide 9 by 3, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 2723.0
If we take 9 away from 9, we end up with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 3

Moving on to step 5:
If we divide 5 by 3, we get 1 and a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 27231.0
If we subtract 3 from 5, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 3

Step 6:
25 divided by 3 is 8 with a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 272318.0
If we take 24 away from 25, we end up 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.

Advancing to step 7:
The number 3 fits into 10 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 272318.3
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.

On 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: 272318.33
If we take 9 away from 10, we end up 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.

The quotient of the division is 272318.33, and the remainder is 0.001.
