256359 ÷ 78 
Our goal is to divide 256359 by 78.

Moving on to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
The next digit of our result is 0. 
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

Step 2:
78 goes into 25 0 times with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Take the next digit (6) from the dividend and append it to 25, then repeat: 256 / 78

Step 3:
78 goes into 256 3 times with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 234 from 256 to get 22.
Include the next digit (3) from the dividend after 22, then repeat: 223 / 78

Moving on to step 4:
The number 78 fits into 223 2 times, leaving a remainder of 67.
Record the quotient 2 as the next digit in the result. 
Result so far: 32.0
The remainder is 67 after subtracting 156 from 223.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 78

Step 5:
675 divided by 78 is 8 with a remainder of 51.
Record the quotient 8 as the next digit in the result. 
Result so far: 328.0
The remainder is 51 after subtracting 624 from 675.
Append the next digit (9) from the dividend to 51 and continue with: 519 / 78

Let's proceed to step 6:
78 goes into 519 6 times with a remainder of 51.
The next digit of our result is 6. 
Result so far: 3286.0
Subtracting 468 from 519 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
78 goes into 510 6 times with a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 3286.6
Subtracting 468 from 510 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 8:
78 goes into 420 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 3286.65
If we take 390 away from 420, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
78 can be fit into 300 3 times, resulting in a remainder of 66.
The number 3 becomes the next digit in our result. 
Result so far: 3286.653
Subtract 234 from 300 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 10:
78 goes into 660 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 3286.6538
If we subtract 624 from 660, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 11:
360 divided by 78 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 3286.65384
The remainder is 48 after subtracting 312 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 12:
78 goes into 480 6 times with a remainder of 12.
The next digit of our result is 6. 
Result so far: 3286.653846
If we subtract 468 from 480, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 13:
The number 78 fits into 120 1 times, leaving a remainder of 42.
Record the quotient 1 as the next digit in the result. 
Result so far: 3286.6538461
If we subtract 78 from 120, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 14:
78 can be fit into 420 5 times, resulting in a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 3286.65384615
If we subtract 390 from 420, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 3286.65384615 with a remainder of 3e-08.
