We're dividing 570582 by 51 
Let's see how many times 51 fits into 570582.

Step 1:
51 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 51

Let's proceed to step 2:
If we divide 57 by 51, we get 1 and a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 51 from 57, we get 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 51

Advancing to step 3:
If we divide 60 by 51, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 51 from 60 leaves us with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 51

Step 4:
51 goes into 95 1 times with a remainder of 44.
Record the quotient 1 as the next digit in the result. 
Result so far: 111.0
The remainder is 44 after subtracting 51 from 95.
Bring next digit (8) of the dividend behind the 44 and repeat the process: 448 / 51

Step 5:
448 divided by 51 is 8 with a remainder of 40.
Write down 8 as next digit of the result. 
Result so far: 1118.0
Subtract 408 from 448 to get 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 51

Going ahead to step 6:
If we divide 402 by 51, we get 7 and a remainder of 45.
Use 7 as the next digit of our solution. 
Result so far: 11187.0
The remainder is 45 after subtracting 357 from 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
When dividing 450 by 51, we get 8 with a remainder of 42.
The number 8 becomes the next digit in our result. 
Result so far: 11187.8
Subtract 408 from 450 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 8:
420 divided by 51 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 11187.88
Deduct 408 from 420 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 11187.88, and the remainder is 0.012.
