150640 divided by 12 
We're looking to find how many times 12 goes into 150640.

Let's proceed to step 1:
12 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 12

On to step 2:
12 can be fit into 15 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 12 from 15 and we're left with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 12

Moving on to step 3:
30 divided by 12 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 24 from 30 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Let's proceed to step 4:
12 can be fit into 66 5 times, resulting in a remainder of 6.
Write down 5 as next digit of the result. 
Result so far: 125.0
The remainder is 6 after subtracting 60 from 66.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 12

Going ahead to step 5:
12 goes into 64 5 times with a remainder of 4.
The next digit of our result is 5. 
Result so far: 1255.0
Subtract 60 from 64 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 12

Step 6:
If we divide 40 by 12, we get 3 and a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 12553.0
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.

Moving on to step 7:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 12553.3
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.

Moving on to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
Record the quotient 3 as the next digit in the result. 
Result so far: 12553.33
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.

The final result is 12553.33 with a remainder of 0.004.
