We look at the division of 665385 by 12 
We're looking to find how many times 12 goes into 665385.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 12

Step 2:
66 divided by 12 is 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 60 from 66 and we're left with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 12

On to step 3:
If we divide 65 by 12, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
If we take 60 away from 65, we end up with 5.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 12

Going ahead to step 4:
12 can be fit into 53 4 times, resulting in a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 554.0
Deduct 48 from 53 and we're left with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

Moving on to step 5:
When dividing 58 by 12, we get 4 with a remainder of 10.
The number 4 becomes the next digit in our result. 
Result so far: 5544.0
Subtract 48 from 58 to get 10.
Append the next digit (5) from the dividend to 10 and continue with: 105 / 12

Going ahead to step 6:
12 goes into 105 8 times with a remainder of 9.
The next digit of our result is 8. 
Result so far: 55448.0
The remainder is 9 after subtracting 96 from 105.
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:
The number 12 fits into 90 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 55448.7
If we subtract 84 from 90, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 8:
60 divided by 12 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 55448.75
Subtract 60 from 60 to 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.
Write down 0 as next digit of the result. 
Result so far: 55448.75
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
If we divide 0 by 12, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 55448.75
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 55448.75 with a remaining 0.0.
