We're dividing 255487 by 78 
Our goal is to divide 255487 by 78.

Step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 78

Let's proceed to step 2:
If we divide 25 by 78, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (5) from the dividend, add it to 25, then carry on: 255 / 78

Step 3:
The number 78 fits into 255 3 times, leaving a remainder of 21.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 234 from 255, we get 21.
Bring next digit (4) of the dividend behind the 21 and repeat the process: 214 / 78

Moving on to step 4:
78 can be fit into 214 2 times, resulting in a remainder of 58.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtracting 156 from 214 leaves us with 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 78

On to step 5:
If we divide 588 by 78, we get 7 and a remainder of 42.
Record the quotient 7 as the next digit in the result. 
Result so far: 327.0
The remainder is 42 after subtracting 546 from 588.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 78

Going ahead to step 6:
78 can be fit into 427 5 times, resulting in a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 3275.0
Deduct 390 from 427 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
78 goes into 370 4 times with a remainder of 58.
Use 4 as the next digit of our solution. 
Result so far: 3275.4
If we take 312 away from 370, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 8:
The number 78 fits into 580 7 times, leaving a remainder of 34.
The next digit of our result is 7. 
Result so far: 3275.47
Subtract 546 from 580 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 9:
When dividing 340 by 78, we get 4 with a remainder of 28.
Write down 4 as next digit of the result. 
Result so far: 3275.474
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 10:
The number 78 fits into 280 3 times, leaving a remainder of 46.
The number 3 becomes the next digit in our result. 
Result so far: 3275.4743
The remainder is 46 after subtracting 234 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 11:
If we divide 460 by 78, we get 5 and a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 3275.47435
Subtracting 390 from 460 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 12:
700 divided by 78 is 8 with a remainder of 76.
Use 8 as the next digit of our solution. 
Result so far: 3275.474358
The remainder is 76 after subtracting 624 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 13:
When dividing 760 by 78, we get 9 with a remainder of 58.
The next digit of our result is 9. 
Result so far: 3275.4743589
Deduct 702 from 760 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 14:
78 goes into 580 7 times with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 3275.47435897
Subtracting 546 from 580 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 3275.47435897 with a remaining 3.4e-08.
