We divide 647854 by 80
We want to divide 647854 by 80.

On to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 80

Going ahead to step 2:
When dividing 64 by 80, we get 0 with a remainder of 64.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 80

Advancing to step 3:
647 divided by 80 is 8 with a remainder of 7.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 640 from 647 leaves us with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 80

Step 4:
80 goes into 78 0 times with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 80.0
Subtracting 0 from 78 leaves us with 78.
Take the next digit (5) from the dividend and append it to 78, then repeat: 785 / 80

Advancing to step 5:
The number 80 fits into 785 9 times, leaving a remainder of 65.
The number 9 becomes the next digit in our result. 
Result so far: 809.0
Subtracting 720 from 785 leaves us with 65.
Bring next digit (4) of the dividend behind the 65 and repeat the process: 654 / 80

Step 6:
The number 80 fits into 654 8 times, leaving a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 8098.0
If we subtract 640 from 654, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
The number 80 fits into 140 1 times, leaving a remainder of 60.
Record the quotient 1 as the next digit in the result. 
Result so far: 8098.1
Deduct 80 from 140 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.

Advancing to step 8:
If we divide 600 by 80, we get 7 and a remainder of 40.
The next digit of our result is 7. 
Result so far: 8098.17
Subtracting 560 from 600 leaves us 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.

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: 8098.175
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.

Advancing to step 10:
80 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8098.175
If we take 0 away from 0, 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.

Let's proceed to step 11:
0 divided by 80 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8098.175
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.

The quotient of the division is 8098.175, and the remainder is 0.0.
