We look at the division of 804161 by 3 
We're looking to find how many times 3 goes into 804161.

Step 1:
If we divide 8 by 3, we get 2 and a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 6 away from 8, we end up with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 3

Advancing to step 2:
20 divided by 3 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 26.0
If we take 18 away from 20, we end up with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 3

On to step 3:
The number 3 fits into 24 8 times, leaving a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 268.0
If we take 24 away from 24, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 3

Going ahead to step 4:
The number 3 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 2680.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Going ahead 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: 26805.0
If we take 15 away from 16, we end up with 1.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 3

Advancing to step 6:
3 goes into 11 3 times with a remainder of 2.
The next digit of our result is 3. 
Result so far: 268053.0
Subtract 9 from 11 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.

Going ahead to step 7:
The number 3 fits into 20 6 times, leaving a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 268053.6
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.

Let's proceed to step 8:
When dividing 20 by 3, we get 6 with a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 268053.66
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.

The final result is 268053.66 with a remainder of 0.002.
