586851 divided by 12 
We're looking to find how many times 12 goes into 586851.

On to step 1:
12 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 5, we end up with 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 number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 48 away from 58, we end up with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 12

Step 3:
106 divided by 12 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 48.0
If we take 96 away from 106, we end up with 10.
Fetch the next digit (8) from the dividend, attach it to 10 and continue: 108 / 12

On to step 4:
If we divide 108 by 12, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 489.0
Subtract 108 from 108 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 12

Going ahead to step 5:
5 divided by 12 is 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 4890.0
Subtract 0 from 5 to get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

Moving on to step 6:
12 goes into 51 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 48904.0
Subtracting 48 from 51 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
12 can be fit into 30 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 48904.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 8:
12 goes into 60 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 48904.25
If we take 60 away from 60, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48904.25
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 48904.25
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 48904.25 with a balance of 0.0.
