80569564 ÷ 280 
We want to figure out the number of times 80569564 can be divided by 280.

Advancing to step 1:
280 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (0) from the dividend to 8 and continue with: 80 / 280

On to step 2:
280 goes into 80 0 times with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Take the next digit (5) from the dividend and append it to 80, then repeat: 805 / 280

Moving on to step 3:
280 goes into 805 2 times with a remainder of 245.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 560 away from 805, we end up with 245.
Include the next digit (6) from the dividend after 245, then repeat: 2456 / 280

Going ahead to step 4:
When dividing 2456 by 280, we get 8 with a remainder of 216.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 2240 from 2456 to get 216.
Bring next digit (9) of the dividend behind the 216 and repeat the process: 2169 / 280

Step 5:
When dividing 2169 by 280, we get 7 with a remainder of 209.
The next digit of our result is 7. 
Result so far: 287.0
If we take 1960 away from 2169, we end up with 209.
Bring next digit (5) of the dividend behind the 209 and repeat the process: 2095 / 280

Let's proceed to step 6:
If we divide 2095 by 280, we get 7 and a remainder of 135.
Use 7 as the next digit of our solution. 
Result so far: 2877.0
The remainder is 135 after subtracting 1960 from 2095.
Take the next digit (6) from the dividend and append it to 135, then repeat: 1356 / 280

Moving on to step 7:
1356 divided by 280 is 4 with a remainder of 236.
Put 4 as the next digit of the answer. 
Result so far: 28774.0
If we subtract 1120 from 1356, we get 236.
Bring next digit (4) of the dividend behind the 236 and repeat the process: 2364 / 280

Step 8:
If we divide 2364 by 280, we get 8 and a remainder of 124.
Use 8 as the next digit of our solution. 
Result so far: 287748.0
The remainder is 124 after subtracting 2240 from 2364.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Let's proceed to step 9:
When dividing 1240 by 280, we get 4 with a remainder of 120.
Write down 4 as next digit of the result. 
Result so far: 287748.4
Subtracting 1120 from 1240 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 10:
280 can be fit into 1200 4 times, resulting in a remainder of 80.
Use 4 as the next digit of our solution. 
Result so far: 287748.44
The remainder is 80 after subtracting 1120 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 287748.44 and a remainder of 0.08.
