86563 ÷ 28 
We're looking to find how many times 28 goes into 86563.

Advancing to step 1:
The number 28 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 28

Going ahead to step 2:
If we divide 86 by 28, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 84 from 86 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 28

Let's proceed to step 3:
If we divide 25 by 28, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we take 0 away from 25, we end up with 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 28

Going ahead to step 4:
256 divided by 28 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 309.0
Subtracting 252 from 256 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 28

Moving on to step 5:
The number 28 fits into 43 1 times, leaving a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 3091.0
The remainder is 15 after subtracting 28 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 6:
The number 28 fits into 150 5 times, leaving a remainder of 10.
The next digit of our result is 5. 
Result so far: 3091.5
Deduct 140 from 150 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 7:
If we divide 100 by 28, we get 3 and a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 3091.53
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
28 can be fit into 160 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 3091.535
Subtract 140 from 160 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
28 goes into 200 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 3091.5357
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 10:
28 goes into 40 1 times with a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 3091.53571
Subtract 28 from 40 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
28 can be fit into 120 4 times, resulting in a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 3091.535714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
28 can be fit into 80 2 times, resulting in a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 3091.5357142
Subtract 56 from 80 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
The number 28 fits into 240 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 3091.53571428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 3091.53571428, with a leftover of 1.6e-08.
