We divide 668063 by 80
We want to figure out the number of times 668063 can be divided by 80.

Let's proceed to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 80

Step 2:
66 divided by 80 is 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 80

Step 3:
The number 80 fits into 668 8 times, leaving a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 640 from 668, we get 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 80

Let's proceed to step 4:
80 goes into 280 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 83.0
If we take 240 away from 280, we end up with 40.
Take the next digit (6) from the dividend and append it to 40, then repeat: 406 / 80

Step 5:
The number 80 fits into 406 5 times, leaving a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 835.0
Deduct 400 from 406 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 80

On to step 6:
63 divided by 80 is 0 with a remainder of 63.
The next digit of our result is 0. 
Result so far: 8350.0
If we subtract 0 from 63, we get 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

On to step 7:
630 divided by 80 is 7 with a remainder of 70.
The next digit of our result is 7. 
Result so far: 8350.7
Subtracting 560 from 630 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 8:
80 can be fit into 700 8 times, resulting in a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 8350.78
Deduct 640 from 700 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.

Step 9:
When dividing 600 by 80, we get 7 with a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 8350.787
If we take 560 away from 600, we end up with 40.
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 10:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8350.7875
Deduct 400 from 400 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.

Moving on to step 11:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8350.7875
Subtracting 0 from 0 leaves us 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 12:
The number 80 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 8350.7875
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.

After the division, we end up with 8350.7875 and a remainder of 0.0.
