We divide 660362 by 80
We're looking to find how many times 80 goes into 660362.

Going ahead to step 1:
80 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 80

Moving on to step 2:
When dividing 66 by 80, we get 0 with a remainder of 66.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 80

Advancing to step 3:
660 divided by 80 is 8 with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 640 from 660 and we're left with 20.
Take the next digit (3) from the dividend and append it to 20, then repeat: 203 / 80

On to step 4:
80 can be fit into 203 2 times, resulting in a remainder of 43.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Deduct 160 from 203 and we're left with 43.
Grab the next digit (6) from the dividend, add it to 43, then carry on: 436 / 80

Step 5:
80 goes into 436 5 times with a remainder of 36.
The next digit of our result is 5. 
Result so far: 825.0
Deduct 400 from 436 and we're left with 36.
Include the next digit (2) from the dividend after 36, then repeat: 362 / 80

Going ahead to step 6:
If we divide 362 by 80, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 8254.0
If we take 320 away from 362, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 80 is 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 8254.5
The remainder is 20 after subtracting 400 from 420.
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:
200 divided by 80 is 2 with a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 8254.52
The remainder is 40 after subtracting 160 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 80 fits into 400 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8254.525
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.

Moving on to step 10:
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: 8254.525
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.

Advancing to step 11:
If we divide 0 by 80, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8254.525
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.

After the division, we end up with 8254.525 and a remainder of 0.0.
