We're dividing 775802 by 3 
Let's see how many times 3 fits into 775802.

Step 1:
3 goes into 7 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 6 from 7, we get 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 3

Moving on to step 2:
If we divide 17 by 3, we get 5 and a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 25.0
If we subtract 15 from 17, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 3

Moving on to step 3:
3 goes into 25 8 times with a remainder of 1.
Use 8 as the next digit of our solution. 
Result so far: 258.0
If we take 24 away from 25, we end up with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 3

On to step 4:
When dividing 18 by 3, we get 6 with a remainder of 0.
Put 6 as the next digit of the answer. 
Result so far: 2586.0
The remainder is 0 after subtracting 18 from 18.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 3

Step 5:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 25860.0
If we take 0 away from 0, we end up with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Let's proceed to step 6:
The number 3 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 258600.0
The remainder is 2 after subtracting 0 from 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.
Put 6 as the next digit of the answer. 
Result so far: 258600.6
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.

Step 8:
If we divide 20 by 3, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 258600.66
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.

The final result is 258600.66 with a remainder of 0.002.
