We're dividing 591462 by 12 
Let's see how many times 12 fits into 591462.

Advancing to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 12

Let's proceed to step 2:
59 divided by 12 is 4 with a remainder of 11.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 48 from 59 to get 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 12

Step 3:
If we divide 111 by 12, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 49.0
If we subtract 108 from 111, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 12

Advancing to step 4:
12 goes into 34 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 492.0
If we subtract 24 from 34, we get 10.
Bring next digit (6) of the dividend behind the 10 and repeat the process: 106 / 12

Advancing to step 5:
If we divide 106 by 12, we get 8 and a remainder of 10.
Use 8 as the next digit of our solution. 
Result so far: 4928.0
The remainder is 10 after subtracting 96 from 106.
Take the next digit (2) from the dividend and append it to 10, then repeat: 102 / 12

Advancing to step 6:
102 divided by 12 is 8 with a remainder of 6.
The number 8 becomes the next digit in our result. 
Result so far: 49288.0
Deduct 96 from 102 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.

Going ahead to step 7:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 49288.5
Subtracting 60 from 60 leaves us 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.

Let's proceed to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 49288.5
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.

Step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 49288.5
Subtracting 0 from 0 leaves us 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.

The final outcome is 49288.5, with a leftover of 0.0.
