664512 ÷ 27 
Let's see how many times 27 fits into 664512.

Step 1:
6 divided by 27 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 27

On to step 2:
66 divided by 27 is 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 54 away from 66, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 27

Advancing to step 3:
When dividing 124 by 27, we get 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 24.0
If we subtract 108 from 124, we get 16.
Bring next digit (5) of the dividend behind the 16 and repeat the process: 165 / 27

On to step 4:
If we divide 165 by 27, we get 6 and a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 246.0
Subtract 162 from 165 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 27

Advancing to step 5:
When dividing 31 by 27, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 2461.0
Deduct 27 from 31 and we're left with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 27

Moving on to step 6:
42 divided by 27 is 1 with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 24611.0
Deduct 27 from 42 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
If we divide 150 by 27, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 24611.5
Subtracting 135 from 150 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
The number 27 fits into 150 5 times, leaving a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 24611.55
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 24611.55, with a leftover of 0.015.
