Let's divide 590636 by 12
We want to figure out the number of times 590636 can be divided by 12.

Step 1:
5 divided by 12 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Let's proceed to step 2:
12 goes into 59 4 times with a remainder of 11.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 48 from 59 leaves us with 11.
Append the next digit (0) from the dividend to 11 and continue with: 110 / 12

Advancing to step 3:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtracting 108 from 110 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

Moving on to step 4:
12 can be fit into 26 2 times, resulting in a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 492.0
Subtracting 24 from 26 leaves us with 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 12

Moving on to step 5:
The number 12 fits into 23 1 times, leaving a remainder of 11.
Use 1 as the next digit of our solution. 
Result so far: 4921.0
If we subtract 12 from 23, we get 11.
Fetch the next digit (6) from the dividend, attach it to 11 and continue: 116 / 12

Moving on to step 6:
When dividing 116 by 12, we get 9 with a remainder of 8.
Use 9 as the next digit of our solution. 
Result so far: 49219.0
If we take 108 away from 116, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 49219.6
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
12 goes into 80 6 times with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 49219.66
Deduct 72 from 80 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 49219.66 with a remainder of 0.008.
