649880 divided by 80 
We're looking to find how many times 80 goes into 649880.

Let's proceed 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
Deduct 0 from 6 and we're left with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 80

Let's proceed to step 2:
64 divided by 80 is 0 with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Fetch the next digit (9) from the dividend, attach it to 64 and continue: 649 / 80

Advancing to step 3:
649 divided by 80 is 8 with a remainder of 9.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 640 from 649 and we're left with 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 80

Let's proceed to step 4:
80 goes into 98 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
The remainder is 18 after subtracting 80 from 98.
Take the next digit (8) from the dividend and append it to 18, then repeat: 188 / 80

On to step 5:
When dividing 188 by 80, we get 2 with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 812.0
If we take 160 away from 188, we end up with 28.
Include the next digit (0) from the dividend after 28, then repeat: 280 / 80

Moving on to step 6:
When dividing 280 by 80, we get 3 with a remainder of 40.
The next digit of our result is 3. 
Result so far: 8123.0
Subtract 240 from 280 to 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 7:
80 goes into 400 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 8123.5
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.

Let's proceed to step 8:
0 divided by 80 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8123.5
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.

Step 9:
0 divided by 80 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8123.5
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.

In conclusion, the division gives 8123.5 with a balance of 0.0.
