586837 ÷ 12 
We're looking to find how many times 12 goes into 586837.

Going ahead to step 1:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 12

Going ahead to step 2:
If we divide 58 by 12, we get 4 and a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 10 after subtracting 48 from 58.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 12

Advancing to step 3:
If we divide 106 by 12, we get 8 and a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 48.0
Deduct 96 from 106 and we're left with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 12

Going ahead to step 4:
When dividing 108 by 12, we get 9 with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 489.0
Subtracting 108 from 108 leaves us with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 12

Going ahead to step 5:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 4890.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 12

Let's proceed to step 6:
12 can be fit into 37 3 times, resulting in a remainder of 1.
Put 3 as the next digit of the answer. 
Result so far: 48903.0
Subtracting 36 from 37 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 48903.0
Deduct 0 from 10 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.

Moving on to step 8:
100 divided by 12 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 48903.08
If we take 96 away from 100, 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.

On to step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 48903.083
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.

Let's proceed to step 10:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 48903.0833
Subtract 36 from 40 to 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 48903.0833 with a remainder of 4e-05.
