We're dividing 150297 by 12 
We want to divide 150297 by 12.

Moving on to step 1:
When dividing 1 by 12, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 12

Let's proceed to step 2:
If we divide 15 by 12, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 3 after subtracting 12 from 15.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Step 3:
If we divide 30 by 12, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 6 after subtracting 24 from 30.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 12

Moving on to step 4:
The number 12 fits into 62 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 2 after subtracting 60 from 62.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 12

Advancing to step 5:
12 can be fit into 29 2 times, resulting in a remainder of 5.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
The remainder is 5 after subtracting 24 from 29.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 12

Going ahead to step 6:
If we divide 57 by 12, we get 4 and a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 12524.0
If we subtract 48 from 57, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
When dividing 90 by 12, we get 7 with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 12524.7
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.

Step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 12524.75
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:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 12524.75
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 10:
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: 12524.75
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.

The quotient of the division is 12524.75, and the remainder is 0.0.
