Let's divide 660503 by 78
Let's see how many times 78 fits into 660503.

On to step 1:
6 divided by 78 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 78

Advancing to step 2:
66 divided by 78 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 78

Step 3:
78 goes into 660 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 624 from 660 to get 36.
Grab the next digit (5) from the dividend, add it to 36, then carry on: 365 / 78

Going ahead to step 4:
78 goes into 365 4 times with a remainder of 53.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 312 from 365, we get 53.
Take the next digit (0) from the dividend and append it to 53, then repeat: 530 / 78

Moving on to step 5:
530 divided by 78 is 6 with a remainder of 62.
Use 6 as the next digit of our solution. 
Result so far: 846.0
If we take 468 away from 530, we end up with 62.
Include the next digit (3) from the dividend after 62, then repeat: 623 / 78

On to step 6:
623 divided by 78 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 8467.0
If we take 546 away from 623, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 7:
When dividing 770 by 78, we get 9 with a remainder of 68.
The number 9 becomes the next digit in our result. 
Result so far: 8467.9
The remainder is 68 after subtracting 702 from 770.
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 8:
The number 78 fits into 680 8 times, leaving a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8467.98
If we subtract 624 from 680, we 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.

Let's proceed to step 9:
The number 78 fits into 560 7 times, leaving a remainder of 14.
Put 7 as the next digit of the answer. 
Result so far: 8467.987
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.

Let's proceed to step 10:
If we divide 140 by 78, we get 1 and a remainder of 62.
Put 1 as the next digit of the answer. 
Result so far: 8467.9871
Subtracting 78 from 140 leaves us 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.

On to step 11:
When dividing 620 by 78, we get 7 with a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 8467.98717
If we take 546 away from 620, we end up 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.

On to step 12:
78 goes into 740 9 times with a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 8467.987179
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.

Going ahead to step 13:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 8467.9871794
Subtracting 312 from 380 leaves us 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.

Advancing to step 14:
78 goes into 680 8 times with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 8467.98717948
If we take 624 away from 680, we end up with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

The quotient of the division is 8467.98717948, and the remainder is 5.6e-08.
