We look at the division of 582850 by 12 
Our goal is to divide 582850 by 12.

On to step 1:
If we divide 5 by 12, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Moving on to step 2:
12 goes into 58 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 48 from 58 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 12

Going ahead to step 3:
The number 12 fits into 102 8 times, leaving a remainder of 6.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 96 from 102 and we're left with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 12

Advancing to step 4:
12 can be fit into 68 5 times, resulting in a remainder of 8.
Record the quotient 5 as the next digit in the result. 
Result so far: 485.0
The remainder is 8 after subtracting 60 from 68.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 12

On to step 5:
The number 12 fits into 85 7 times, leaving a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 4857.0
If we subtract 84 from 85, we get 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Moving on to step 6:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 48570.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 48570.8
Deduct 96 from 100 and we're left 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.

Let's proceed to step 8:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 48570.83
Subtracting 36 from 40 leaves us 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.

Going ahead to step 9:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 48570.833
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 48570.833 with a remainder of 0.0004.
