We're dividing 816161 by 3 
Our goal is to divide 816161 by 3.

On to step 1:
When dividing 8 by 3, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 6 from 8 leaves us with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 3

Step 2:
The number 3 fits into 21 7 times, leaving a remainder of 0.
Record the quotient 7 as the next digit in the result. 
Result so far: 27.0
If we take 21 away from 21, we end up with 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 3

Going ahead to step 3:
When dividing 6 by 3, we get 2 with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 272.0
If we subtract 6 from 6, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Going ahead to step 4:
When dividing 1 by 3, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 2720.0
If we subtract 0 from 1, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Let's proceed to step 5:
If we divide 16 by 3, we get 5 and a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 27205.0
The remainder is 1 after subtracting 15 from 16.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Let's proceed to step 6:
3 goes into 11 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 272053.0
The remainder is 2 after subtracting 9 from 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 3, we get 6 and a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 272053.6
If we take 18 away from 20, we end up 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:
20 divided by 3 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 272053.66
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 272053.66 and a remainder of 0.002.
