We look at the division of 354582 by 12 
We're looking to find how many times 12 goes into 354582.

Moving on to step 1:
12 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 12

Going ahead to step 2:
If we divide 35 by 12, we get 2 and a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 24 from 35 and we're left with 11.
Include the next digit (4) from the dividend after 11, then repeat: 114 / 12

Advancing to step 3:
If we divide 114 by 12, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 29.0
If we take 108 away from 114, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

Let's proceed to step 4:
The number 12 fits into 65 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 295.0
Subtracting 60 from 65 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 12

Going ahead to step 5:
When dividing 58 by 12, we get 4 with a remainder of 10.
Record the quotient 4 as the next digit in the result. 
Result so far: 2954.0
Subtracting 48 from 58 leaves us with 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 12

Advancing to step 6:
12 goes into 102 8 times with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 29548.0
The remainder is 6 after subtracting 96 from 102.
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.
The next digit of our result is 5. 
Result so far: 29548.5
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.

Moving on to step 8:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 29548.5
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.

Going ahead to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 29548.5
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.

The final result is 29548.5 with a remainder of 0.0.
