We're dividing 287285 by 78 
We want to divide 287285 by 78.

On to step 1:
The number 78 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 78

Moving on to step 2:
28 divided by 78 is 0 with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 28 and we're left with 28.
Fetch the next digit (7) from the dividend, attach it to 28 and continue: 287 / 78

Step 3:
The number 78 fits into 287 3 times, leaving a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 234 from 287 and we're left with 53.
Bring next digit (2) of the dividend behind the 53 and repeat the process: 532 / 78

Advancing to step 4:
If we divide 532 by 78, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we take 468 away from 532, we end up with 64.
Include the next digit (8) from the dividend after 64, then repeat: 648 / 78

Advancing to step 5:
648 divided by 78 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 368.0
The remainder is 24 after subtracting 624 from 648.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 78

Advancing to step 6:
245 divided by 78 is 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 3683.0
If we subtract 234 from 245, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
78 goes into 110 1 times with a remainder of 32.
Record the quotient 1 as the next digit in the result. 
Result so far: 3683.1
If we take 78 away from 110, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 8:
78 goes into 320 4 times with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 3683.14
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 78, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 3683.141
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 78 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 3683.141
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
If we divide 200 by 78, we get 2 and a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 3683.14102
Deduct 156 from 200 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
The number 78 fits into 440 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 3683.141025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 13:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 3683.1410256
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
320 divided by 78 is 4 with a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 3683.14102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 3683.14102564 with a remainder of 8e-09.
