We divide 665476 by 80
Let's see how many times 80 fits into 665476.

Let's proceed to step 1:
The number 80 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 80

Going ahead to step 2:
If we divide 66 by 80, we get 0 and a remainder of 66.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 80

Let's proceed to step 3:
The number 80 fits into 665 8 times, leaving a remainder of 25.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 25 after subtracting 640 from 665.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 80

Let's proceed to step 4:
254 divided by 80 is 3 with a remainder of 14.
The next digit of our result is 3. 
Result so far: 83.0
Subtracting 240 from 254 leaves us with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 80

On to step 5:
80 can be fit into 147 1 times, resulting in a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 831.0
Deduct 80 from 147 and we're left with 67.
Grab the next digit (6) from the dividend, add it to 67, then carry on: 676 / 80

On to step 6:
80 goes into 676 8 times with a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 8318.0
Subtract 640 from 676 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 7:
80 can be fit into 360 4 times, resulting in a remainder of 40.
The next digit of our result is 4. 
Result so far: 8318.4
If we subtract 320 from 360, 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:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 8318.45
If we take 400 away from 400, we end up 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.

Going ahead to step 9:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 8318.45
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.

On to step 10:
0 divided by 80 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 8318.45
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 final result is 8318.45 with a remainder of 0.0.
