144028 ÷ 12 
Let's see how many times 12 fits into 144028.

Advancing to step 1:
1 divided by 12 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 12

On to step 2:
When dividing 14 by 12, we get 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 12 from 14, we get 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 12

Going ahead to step 3:
The number 12 fits into 24 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we take 24 away from 24, we end up with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 12

Advancing to step 4:
0 divided by 12 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 120.0
If we subtract 0 from 0, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 12

Let's proceed to step 5:
12 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 1200.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 12

Advancing to step 6:
If we divide 28 by 12, we get 2 and a remainder of 4.
Record the quotient 2 as the next digit in the result. 
Result so far: 12002.0
Subtract 24 from 28 to 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.

Advancing to step 7:
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: 12002.3
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.

Going ahead to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 12002.33
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 12002.33 with a remaining 0.004.
