648987 ÷ 80 
We're looking to find how many times 80 goes into 648987.

Moving on to step 1:
If we divide 6 by 80, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 80

Step 2:
80 can be fit into 64 0 times, resulting in a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 64, we get 64.
Bring next digit (8) of the dividend behind the 64 and repeat the process: 648 / 80

On to step 3:
80 can be fit into 648 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 640 from 648 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 80

On to step 4:
89 divided by 80 is 1 with a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 80 away from 89, we end up with 9.
Fetch the next digit (8) from the dividend, attach it to 9 and continue: 98 / 80

On to step 5:
80 can be fit into 98 1 times, resulting in a remainder of 18.
The next digit of our result is 1. 
Result so far: 811.0
If we subtract 80 from 98, we get 18.
Grab the next digit (7) from the dividend, add it to 18, then carry on: 187 / 80

Going ahead to step 6:
If we divide 187 by 80, we get 2 and a remainder of 27.
The next digit of our result is 2. 
Result so far: 8112.0
Deduct 160 from 187 and we're left with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 80, we get 3 with a remainder of 30.
The number 3 becomes the next digit in our result. 
Result so far: 8112.3
If we take 240 away from 270, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
80 goes into 300 3 times with a remainder of 60.
Record the quotient 3 as the next digit in the result. 
Result so far: 8112.33
Subtract 240 from 300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Our division results in 8112.33 with a remaining 0.06.
