768256 divided by 3 
Let's see how many times 3 fits into 768256.

Step 1:
3 goes into 7 2 times with a remainder of 1.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 1 after subtracting 6 from 7.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 3

Let's proceed to step 2:
The number 3 fits into 16 5 times, leaving a remainder of 1.
Use 5 as the next digit of our solution. 
Result so far: 25.0
Subtracting 15 from 16 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 3

Advancing to step 3:
18 divided by 3 is 6 with a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 256.0
Subtracting 18 from 18 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 3

Advancing to step 4:
3 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 2560.0
If we take 0 away from 2, we end up with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 3

On to step 5:
The number 3 fits into 25 8 times, leaving a remainder of 1.
The next digit of our result is 8. 
Result so far: 25608.0
If we take 24 away from 25, we end up with 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 3

Advancing to step 6:
3 goes into 16 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 256085.0
If we take 15 away from 16, 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.

On to step 7:
If we divide 10 by 3, we get 3 and a remainder of 1.
Record the quotient 3 as the next digit in the result. 
Result so far: 256085.3
Deduct 9 from 10 and we're left 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.

Step 8:
3 goes into 10 3 times with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 256085.33
If we subtract 9 from 10, we get 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 final result is 256085.33 with a remainder of 0.001.
