Let's divide 280563 by 80
We want to figure out the number of times 280563 can be divided by 80.

Step 1:
80 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 80

Step 2:
80 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (0) from the dividend to 28 and continue with: 280 / 80

Going ahead to step 3:
When dividing 280 by 80, we get 3 with a remainder of 40.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 240 away from 280, we end up with 40.
Append the next digit (5) from the dividend to 40 and continue with: 405 / 80

Moving on to step 4:
80 can be fit into 405 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
The remainder is 5 after subtracting 400 from 405.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 80

Advancing to step 5:
When dividing 56 by 80, we get 0 with a remainder of 56.
Use 0 as the next digit of our solution. 
Result so far: 350.0
The remainder is 56 after subtracting 0 from 56.
Include the next digit (3) from the dividend after 56, then repeat: 563 / 80

Moving on to step 6:
80 goes into 563 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 3507.0
Deduct 560 from 563 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
30 divided by 80 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 3507.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 80 is 3 with a remainder of 60.
Write down 3 as next digit of the result. 
Result so far: 3507.03
Deduct 240 from 300 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.

On to step 9:
600 divided by 80 is 7 with a remainder of 40.
The next digit of our result is 7. 
Result so far: 3507.037
If we subtract 560 from 600, 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.

Moving on to step 10:
400 divided by 80 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 3507.0375
Deduct 400 from 400 and we're left 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:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3507.0375
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.

On to step 12:
80 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3507.0375
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.

Our division results in 3507.0375 with a remaining 0.0.
