257855 ÷ 77 
Let's see how many times 77 fits into 257855.

Going ahead to step 1:
77 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 77

Let's proceed to step 2:
25 divided by 77 is 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 77

On to step 3:
77 can be fit into 257 3 times, resulting in a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 231 away from 257, we end up with 26.
Grab the next digit (8) from the dividend, add it to 26, then carry on: 268 / 77

Step 4:
77 can be fit into 268 3 times, resulting in a remainder of 37.
The next digit of our result is 3. 
Result so far: 33.0
If we take 231 away from 268, we end up with 37.
Include the next digit (5) from the dividend after 37, then repeat: 375 / 77

Step 5:
If we divide 375 by 77, we get 4 and a remainder of 67.
Write down 4 as next digit of the result. 
Result so far: 334.0
Subtracting 308 from 375 leaves us with 67.
Include the next digit (5) from the dividend after 67, then repeat: 675 / 77

Let's proceed to step 6:
77 can be fit into 675 8 times, resulting in a remainder of 59.
The next digit of our result is 8. 
Result so far: 3348.0
Deduct 616 from 675 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 7:
The number 77 fits into 590 7 times, leaving a remainder of 51.
Record the quotient 7 as the next digit in the result. 
Result so far: 3348.7
Subtract 539 from 590 to get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 8:
If we divide 510 by 77, we get 6 and a remainder of 48.
Put 6 as the next digit of the answer. 
Result so far: 3348.76
Subtracting 462 from 510 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 9:
When dividing 480 by 77, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 3348.766
Subtracting 462 from 480 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 3348.766 with a remainder of 0.0018.
