544102 ÷ 12 
Let's see how many times 12 fits into 544102.

Let's proceed to step 1:
12 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 12

On to step 2:
When dividing 54 by 12, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 48 from 54 to get 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 12

Step 3:
12 goes into 64 5 times with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtract 60 from 64 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 12

Moving on to step 4:
41 divided by 12 is 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 453.0
Deduct 36 from 41 and we're left with 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 12

Step 5:
12 goes into 50 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 4534.0
Subtract 48 from 50 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 12

On to step 6:
12 goes into 22 1 times with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 45341.0
If we subtract 12 from 22, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
100 divided by 12 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 45341.8
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
40 divided by 12 is 3 with a remainder of 4.
The next digit of our result is 3. 
Result so far: 45341.83
If we subtract 36 from 40, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 45341.833
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 45341.833, with a leftover of 0.0004.
