644247 divided by 27 
Let's see how many times 27 fits into 644247.

Step 1:
The number 27 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 27

Going ahead to step 2:
If we divide 64 by 27, we get 2 and a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 54 from 64 leaves us with 10.
Append the next digit (4) from the dividend to 10 and continue with: 104 / 27

Let's proceed to step 3:
27 can be fit into 104 3 times, resulting in a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 23.0
Subtracting 81 from 104 leaves us with 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 27

Advancing to step 4:
The number 27 fits into 232 8 times, leaving a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 238.0
Subtract 216 from 232 to get 16.
Take the next digit (4) from the dividend and append it to 16, then repeat: 164 / 27

Moving on to step 5:
The number 27 fits into 164 6 times, leaving a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 2386.0
The remainder is 2 after subtracting 162 from 164.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 27

On to step 6:
The number 27 fits into 27 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 23861.0
Deduct 27 from 27 and we're left 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 7:
If we divide 0 by 27, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 23861.0
Subtract 0 from 0 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.

Let's proceed to step 8:
27 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 23861.0
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.

The final outcome is 23861.0, with a leftover of 0.0.
