2 divided by 565 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 565

On to step 2:
28 divided by 565 is 0 with 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.
Take the next digit (5) from the dividend and append it to 28, then repeat: 285 / 565

Let's proceed to step 3:
When dividing 285 by 565, we get 0 with a remainder of 285.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 285, we end up with 285.
Grab the next digit (1) from the dividend, add it to 285, then carry on: 2851 / 565

Moving on to step 4:
The number 565 fits into 2851 5 times, leaving a remainder of 26.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 2825 away from 2851, we end up with 26.
Append the next digit (8) from the dividend to 26 and continue with: 268 / 565

On to step 5:
565 goes into 268 0 times with a remainder of 268.
Use 0 as the next digit of our solution. 
Result so far: 50.0
Subtract 0 from 268 to get 268.
Fetch the next digit (6) from the dividend, attach it to 268 and continue: 2686 / 565

On to step 6:
565 can be fit into 2686 4 times, resulting in a remainder of 426.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
If we take 2260 away from 2686, we end up with 426.
Bring next digit (9) of the dividend behind the 426 and repeat the process: 4269 / 565

Moving on to step 7:
565 goes into 4269 7 times with a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 5047.0
If we take 3955 away from 4269, we end up with 314.
Bring next digit (0) of the dividend behind the 314 and repeat the process: 3140 / 565

Let's proceed to step 8:
3140 divided by 565 is 5 with a remainder of 315.
The next digit of our result is 5. 
Result so far: 50475.0
The remainder is 315 after subtracting 2825 from 3140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3150, and continue the process.

Going ahead to step 9:
When dividing 3150 by 565, we get 5 with a remainder of 325.
The number 5 becomes the next digit in our result. 
Result so far: 50475.5
Deduct 2825 from 3150 and we're left with 325.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3250, and continue the process.

Moving on to step 10:
The number 565 fits into 3250 5 times, leaving a remainder of 425.
The number 5 becomes the next digit in our result. 
Result so far: 50475.55
Deduct 2825 from 3250 and we're left with 425.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4250, and continue the process.

Our division results in 50475.55 with a remaining 0.425.
