Let's divide 591666 by 12
Let's see how many times 12 fits into 591666.

On to step 1:
When dividing 5 by 12, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 12

Moving on to step 2:
59 divided by 12 is 4 with a remainder of 11.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 48 from 59 to get 11.
Bring next digit (1) of the dividend behind the 11 and repeat the process: 111 / 12

Let's proceed to step 3:
If we divide 111 by 12, we get 9 and a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 49.0
If we take 108 away from 111, we end up with 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 12

Step 4:
12 can be fit into 36 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 493.0
Deduct 36 from 36 and we're left with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 12

Let's proceed to step 5:
6 divided by 12 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 4930.0
If we subtract 0 from 6, we get 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 12

Advancing to step 6:
66 divided by 12 is 5 with a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 49305.0
Deduct 60 from 66 and we're left 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.

Let's proceed to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 49305.5
Deduct 60 from 60 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.

Going ahead to step 8:
0 divided by 12 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 49305.5
Subtract 0 from 0 to get 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 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49305.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 49305.5 with a remainder of 0.0.
