288497 ÷ 78 
Let's see how many times 78 fits into 288497.

On to step 1:
When dividing 2 by 78, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Append the next digit (8) from the dividend to 2 and continue with: 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
Subtract 0 from 28 to get 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 78

Going ahead to step 3:
When dividing 288 by 78, we get 3 with a remainder of 54.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 234 from 288 to get 54.
Append the next digit (4) from the dividend to 54 and continue with: 544 / 78

Advancing to step 4:
The number 78 fits into 544 6 times, leaving a remainder of 76.
Put 6 as the next digit of the answer. 
Result so far: 36.0
The remainder is 76 after subtracting 468 from 544.
Fetch the next digit (9) from the dividend, attach it to 76 and continue: 769 / 78

Step 5:
769 divided by 78 is 9 with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 369.0
Subtracting 702 from 769 leaves us with 67.
Include the next digit (7) from the dividend after 67, then repeat: 677 / 78

Going ahead to step 6:
When dividing 677 by 78, we get 8 with a remainder of 53.
The next digit of our result is 8. 
Result so far: 3698.0
Subtract 624 from 677 to get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

On to step 7:
78 can be fit into 530 6 times, resulting in a remainder of 62.
Write down 6 as next digit of the result. 
Result so far: 3698.6
The remainder is 62 after subtracting 468 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
The number 78 fits into 620 7 times, leaving a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 3698.67
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
When dividing 740 by 78, we get 9 with a remainder of 38.
Write down 9 as next digit of the result. 
Result so far: 3698.679
If we subtract 702 from 740, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 10:
380 divided by 78 is 4 with a remainder of 68.
The next digit of our result is 4. 
Result so far: 3698.6794
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 11:
If we divide 680 by 78, we get 8 and a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 3698.67948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 12:
When dividing 560 by 78, we get 7 with a remainder of 14.
The next digit of our result is 7. 
Result so far: 3698.679487
If we take 546 away from 560, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
140 divided by 78 is 1 with a remainder of 62.
The number 1 becomes the next digit in our result. 
Result so far: 3698.6794871
Deduct 78 from 140 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
Use 7 as the next digit of our solution. 
Result so far: 3698.67948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

After the division, we end up with 3698.67948717 and a remainder of 7.4e-08.
