We divide 583039 by 12
We're looking to find how many times 12 goes into 583039.

Let's proceed to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Append the next digit (8) from the dividend to 5 and continue with: 58 / 12

Step 2:
The number 12 fits into 58 4 times, leaving a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 48 from 58, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Let's proceed to step 3:
103 divided by 12 is 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 48.0
Deduct 96 from 103 and we're left with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 12

Step 4:
When dividing 70 by 12, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 485.0
If we subtract 60 from 70, we get 10.
Append the next digit (3) from the dividend to 10 and continue with: 103 / 12

On to step 5:
12 can be fit into 103 8 times, resulting in a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 4858.0
If we subtract 96 from 103, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 12

Moving on to step 6:
12 can be fit into 79 6 times, resulting in a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 48586.0
Subtract 72 from 79 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
12 can be fit into 70 5 times, resulting in a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 48586.5
Deduct 60 from 70 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:
12 goes into 100 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 48586.58
Subtracting 96 from 100 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.

Step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 48586.583
Deduct 36 from 40 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.

Step 10:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 48586.5833
Deduct 36 from 40 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.

After the division, we end up with 48586.5833 and a remainder of 4e-05.
