660774 divided by 80 
Let's see how many times 80 fits into 660774.

Let's proceed to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 80

Moving on to step 2:
The number 80 fits into 66 0 times, leaving a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 80

Step 3:
If we divide 660 by 80, we get 8 and a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 640 from 660, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 80

Let's proceed to step 4:
80 goes into 207 2 times with a remainder of 47.
The next digit of our result is 2. 
Result so far: 82.0
Subtracting 160 from 207 leaves us with 47.
Take the next digit (7) from the dividend and append it to 47, then repeat: 477 / 80

Advancing to step 5:
When dividing 477 by 80, we get 5 with a remainder of 77.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
The remainder is 77 after subtracting 400 from 477.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 80

On to step 6:
774 divided by 80 is 9 with a remainder of 54.
The number 9 becomes the next digit in our result. 
Result so far: 8259.0
Subtracting 720 from 774 leaves us 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.

Moving on to step 7:
If we divide 540 by 80, we get 6 and a remainder of 60.
Put 6 as the next digit of the answer. 
Result so far: 8259.6
The remainder is 60 after subtracting 480 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Step 8:
80 can be fit into 600 7 times, resulting in a remainder of 40.
The next digit of our result is 7. 
Result so far: 8259.67
The remainder is 40 after subtracting 560 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
If we divide 400 by 80, we get 5 and a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 8259.675
If we subtract 400 from 400, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
80 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8259.675
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8259.675
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 8259.675, and the remainder is 0.0.
