288513 divided by 78 
Let's see how many times 78 fits into 288513.

Let's proceed to step 1:
2 divided by 78 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 78

Advancing to step 2:
If we divide 28 by 78, we get 0 and a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (8) from the dividend, add it to 28, then carry on: 288 / 78

On to step 3:
The number 78 fits into 288 3 times, leaving a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtracting 234 from 288 leaves us with 54.
Grab the next digit (5) from the dividend, add it to 54, then carry on: 545 / 78

Moving on to step 4:
545 divided by 78 is 6 with a remainder of 77.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 468 from 545, we get 77.
Bring next digit (1) of the dividend behind the 77 and repeat the process: 771 / 78

Let's proceed to step 5:
If we divide 771 by 78, we get 9 and a remainder of 69.
Use 9 as the next digit of our solution. 
Result so far: 369.0
If we take 702 away from 771, we end up with 69.
Grab the next digit (3) from the dividend, add it to 69, then carry on: 693 / 78

On to step 6:
693 divided by 78 is 8 with a remainder of 69.
The next digit of our result is 8. 
Result so far: 3698.0
If we take 624 away from 693, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

On to step 7:
When dividing 690 by 78, we get 8 with a remainder of 66.
The number 8 becomes the next digit in our result. 
Result so far: 3698.8
If we subtract 624 from 690, we 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 8:
If we divide 660 by 78, we get 8 and a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 3698.88
Deduct 624 from 660 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 3698.88, with a leftover of 0.036.
