We're dividing 531666 by 12 
We're looking to find how many times 12 goes into 531666.

Advancing to step 1:
12 goes into 5 0 times with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 12

Going ahead to step 2:
12 can be fit into 53 4 times, resulting in a remainder of 5.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 5 after subtracting 48 from 53.
Grab the next digit (1) from the dividend, add it to 5, then carry on: 51 / 12

Advancing to step 3:
When dividing 51 by 12, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 44.0
Deduct 48 from 51 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 12

Moving on to step 4:
If we divide 36 by 12, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 443.0
If we take 36 away from 36, we end up with 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 12

Advancing to step 5:
If we divide 6 by 12, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 4430.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Moving on to step 6:
66 divided by 12 is 5 with a remainder of 6.
Use 5 as the next digit of our solution. 
Result so far: 44305.0
If we take 60 away from 66, we end up 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:
12 goes into 60 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 44305.5
If we subtract 60 from 60, 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.

Moving on to step 8:
12 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 44305.5
If we take 0 away from 0, we end up 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.

On to step 9:
If we divide 0 by 12, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 44305.5
If we take 0 away from 0, we end up 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.

Our division results in 44305.5 with a remaining 0.0.
