We're dividing 660730 by 80 
Our goal is to divide 660730 by 80.

Advancing to step 1:
When dividing 6 by 80, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 80

Moving on to step 2:
80 can be fit into 66 0 times, resulting in a remainder of 66.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 80

Advancing to step 3:
80 can be fit into 660 8 times, resulting in a remainder of 20.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 640 from 660 and we're left with 20.
Fetch the next digit (7) from the dividend, attach it to 20 and continue: 207 / 80

Step 4:
If we divide 207 by 80, we get 2 and a remainder of 47.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
The remainder is 47 after subtracting 160 from 207.
Fetch the next digit (3) from the dividend, attach it to 47 and continue: 473 / 80

Let's proceed to step 5:
80 goes into 473 5 times with a remainder of 73.
Record the quotient 5 as the next digit in the result. 
Result so far: 825.0
The remainder is 73 after subtracting 400 from 473.
Take the next digit (0) from the dividend and append it to 73, then repeat: 730 / 80

Let's proceed to step 6:
The number 80 fits into 730 9 times, leaving a remainder of 10.
The next digit of our result is 9. 
Result so far: 8259.0
If we take 720 away from 730, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
100 divided by 80 is 1 with a remainder of 20.
Write down 1 as next digit of the result. 
Result so far: 8259.1
If we subtract 80 from 100, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
80 can be fit into 200 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 8259.12
Subtract 160 from 200 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 9:
400 divided by 80 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 8259.125
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.

Going ahead to step 10:
80 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8259.125
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.

Let's proceed to step 11:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8259.125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 8259.125 with a balance of 0.0.
