We divide 668748 by 80
Let's see how many times 80 fits into 668748.

On to step 1:
80 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
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

Going ahead to step 2:
66 divided by 80 is 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Fetch the next digit (8) from the dividend, attach it to 66 and continue: 668 / 80

Advancing to step 3:
The number 80 fits into 668 8 times, leaving a remainder of 28.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 640 from 668, we get 28.
Bring next digit (7) of the dividend behind the 28 and repeat the process: 287 / 80

Advancing to step 4:
80 can be fit into 287 3 times, resulting in a remainder of 47.
Use 3 as the next digit of our solution. 
Result so far: 83.0
If we subtract 240 from 287, we get 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 80

Let's proceed to step 5:
80 goes into 474 5 times with a remainder of 74.
The number 5 becomes the next digit in our result. 
Result so far: 835.0
The remainder is 74 after subtracting 400 from 474.
Bring next digit (8) of the dividend behind the 74 and repeat the process: 748 / 80

Moving on to step 6:
80 can be fit into 748 9 times, resulting in a remainder of 28.
Use 9 as the next digit of our solution. 
Result so far: 8359.0
If we subtract 720 from 748, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 7:
When dividing 280 by 80, we get 3 with a remainder of 40.
Put 3 as the next digit of the answer. 
Result so far: 8359.3
If we subtract 240 from 280, we 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.

Let's proceed to step 8:
When dividing 400 by 80, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8359.35
Subtract 400 from 400 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.

Let's proceed to step 9:
When dividing 0 by 80, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8359.35
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 10:
If we divide 0 by 80, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8359.35
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.

In conclusion, the division gives 8359.35 with a balance of 0.0.
