554409 ÷ 12 
We want to figure out the number of times 554409 can be divided by 12.

Moving on to step 1:
12 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (5) from the dividend and append it to 5, then repeat: 55 / 12

On to step 2:
If we divide 55 by 12, we get 4 and a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 48 from 55 leaves us with 7.
Take the next digit (4) from the dividend and append it to 7, then repeat: 74 / 12

Going ahead to step 3:
12 goes into 74 6 times with a remainder of 2.
The next digit of our result is 6. 
Result so far: 46.0
If we take 72 away from 74, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 12

Moving on to step 4:
24 divided by 12 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 462.0
Deduct 24 from 24 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 12

Moving on to step 5:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 4620.0
If we take 0 away from 0, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 12

Going ahead to step 6:
When dividing 9 by 12, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 46200.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 46200.7
Deduct 84 from 90 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.

Moving on to step 8:
60 divided by 12 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 46200.75
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.

Step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 46200.75
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 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 46200.75
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 46200.75 with a remaining 0.0.
