Let's divide 28245 by 87
Our goal is to divide 28245 by 87.

Step 1:
87 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 87

Going ahead to step 2:
If we divide 28 by 87, we get 0 and a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (2) from the dividend after 28, then repeat: 282 / 87

Step 3:
87 goes into 282 3 times with a remainder of 21.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 261 from 282, we get 21.
Fetch the next digit (4) from the dividend, attach it to 21 and continue: 214 / 87

On to step 4:
The number 87 fits into 214 2 times, leaving a remainder of 40.
The next digit of our result is 2. 
Result so far: 32.0
Subtract 174 from 214 to get 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 87

Going ahead to step 5:
The number 87 fits into 405 4 times, leaving a remainder of 57.
The next digit of our result is 4. 
Result so far: 324.0
Subtract 348 from 405 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 6:
87 goes into 570 6 times with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 324.6
Deduct 522 from 570 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
87 can be fit into 480 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 324.65
Subtracting 435 from 480 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Moving on to step 8:
If we divide 450 by 87, we get 5 and a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 324.655
If we subtract 435 from 450, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

After the division, we end up with 324.655 and a remainder of 0.0015.
