We're dividing 771288 by 3 
We're looking to find how many times 3 goes into 771288.

Step 1:
The number 3 fits into 7 2 times, leaving a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 6 away from 7, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 3

Let's proceed to step 2:
17 divided by 3 is 5 with a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 15 from 17, we get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 3

Let's proceed to step 3:
3 goes into 21 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
Deduct 21 from 21 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 3

On to step 4:
The number 3 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 2570.0
Subtract 0 from 2 to get 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 3

Let's proceed to step 5:
If we divide 28 by 3, we get 9 and a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 25709.0
If we subtract 27 from 28, we get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 3

Step 6:
The number 3 fits into 18 6 times, leaving a remainder of 0.
The next digit of our result is 6. 
Result so far: 257096.0
The remainder is 0 after subtracting 18 from 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
3 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 257096.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
3 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 257096.0
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 257096.0 and a remainder of 0.0.
