554660 ÷ 12 
Our goal is to divide 554660 by 12.

Let's proceed to step 1:
12 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 12

Going ahead to step 2:
55 divided by 12 is 4 with a remainder of 7.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 48 from 55 and we're left with 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 12

Moving on to step 3:
When dividing 74 by 12, we get 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 46.0
If we take 72 away from 74, we end up with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 12

On to step 4:
26 divided by 12 is 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 462.0
If we subtract 24 from 26, we get 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 12

On to step 5:
If we divide 26 by 12, we get 2 and a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 4622.0
Subtract 24 from 26 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

On to step 6:
When dividing 20 by 12, we get 1 with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 46221.0
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 46221.6
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.

On to step 8:
12 goes into 80 6 times with a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 46221.66
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.

Our division results in 46221.66 with a remaining 0.008.
