We divide 663288 by 78
Our goal is to divide 663288 by 78.

Moving on to step 1:
6 divided by 78 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 78

Advancing to step 2:
78 goes into 66 0 times with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (3) from the dividend to 66 and continue with: 663 / 78

Advancing to step 3:
If we divide 663 by 78, we get 8 and a remainder of 39.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 624 away from 663, we end up with 39.
Append the next digit (2) from the dividend to 39 and continue with: 392 / 78

On to step 4:
When dividing 392 by 78, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 2 after subtracting 390 from 392.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 78

Let's proceed to step 5:
The number 78 fits into 28 0 times, leaving a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 850.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 78

Moving on to step 6:
If we divide 288 by 78, we get 3 and a remainder of 54.
The next digit of our result is 3. 
Result so far: 8503.0
Deduct 234 from 288 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 7:
540 divided by 78 is 6 with a remainder of 72.
Write down 6 as next digit of the result. 
Result so far: 8503.6
The remainder is 72 after subtracting 468 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 8:
The number 78 fits into 720 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 8503.69
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
78 can be fit into 180 2 times, resulting in a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 8503.692
The remainder is 24 after subtracting 156 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 10:
When dividing 240 by 78, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 8503.6923
Subtract 234 from 240 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
The number 78 fits into 60 0 times, leaving a remainder of 60.
The number 0 becomes the next digit in our result. 
Result so far: 8503.6923
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 12:
When dividing 600 by 78, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 8503.692307
The remainder is 54 after subtracting 546 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 13:
If we divide 540 by 78, we get 6 and a remainder of 72.
The number 6 becomes the next digit in our result. 
Result so far: 8503.6923076
Subtracting 468 from 540 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 14:
720 divided by 78 is 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 8503.69230769
The remainder is 18 after subtracting 702 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The quotient of the division is 8503.69230769, and the remainder is 1.8e-08.
