648 can be fit into 28 0 times, resulting in a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 648

Going ahead to step 3:
When dividing 287 by 648, we get 0 with a remainder of 287.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 287 to get 287.
Append the next digit (5) from the dividend to 287 and continue with: 2875 / 648

Moving on to step 4:
When dividing 2875 by 648, we get 4 with a remainder of 283.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2592 from 2875 to get 283.
Take the next digit (9) from the dividend and append it to 283, then repeat: 2839 / 648

Advancing to step 5:
648 goes into 2839 4 times with a remainder of 247.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 2592 from 2839 to get 247.
Include the next digit (9) from the dividend after 247, then repeat: 2479 / 648

Moving on to step 6:
The number 648 fits into 2479 3 times, leaving a remainder of 535.
Record the quotient 3 as the next digit in the result. 
Result so far: 443.0
Subtracting 1944 from 2479 leaves us with 535.
Include the next digit (9) from the dividend after 535, then repeat: 5359 / 648

Going ahead to step 7:
When dividing 5359 by 648, we get 8 with a remainder of 175.
Write down 8 as next digit of the result. 
Result so far: 4438.0
If we subtract 5184 from 5359, we get 175.
Bring next digit (3) of the dividend behind the 175 and repeat the process: 1753 / 648

Going ahead to step 8:
When dividing 1753 by 648, we get 2 with a remainder of 457.
Put 2 as the next digit of the answer. 
Result so far: 44382.0
If we subtract 1296 from 1753, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

Let's proceed to step 9:
4570 divided by 648 is 7 with a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 44382.7
Subtracting 4536 from 4570 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 10:
When dividing 340 by 648, we get 0 with a remainder of 340.
The number 0 becomes the next digit in our result. 
Result so far: 44382.7
The remainder is 340 after subtracting 0 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Moving on to step 11:
If we divide 3400 by 648, we get 5 and a remainder of 160.
The next digit of our result is 5. 
Result so far: 44382.705
If we take 3240 away from 3400, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

On to step 12:
1600 divided by 648 is 2 with a remainder of 304.
The number 2 becomes the next digit in our result. 
Result so far: 44382.7052
The remainder is 304 after subtracting 1296 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 13:
3040 divided by 648 is 4 with a remainder of 448.
Use 4 as the next digit of our solution. 
Result so far: 44382.70524
Subtracting 2592 from 3040 leaves us with 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 14:
When dividing 4480 by 648, we get 6 with a remainder of 592.
The number 6 becomes the next digit in our result. 
Result so far: 44382.705246
Deduct 3888 from 4480 and we're left with 592.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 15:
The number 648 fits into 5920 9 times, leaving a remainder of 88.
The number 9 becomes the next digit in our result. 
Result so far: 44382.7052469
Deduct 5832 from 5920 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Going ahead to step 16:
When dividing 880 by 648, we get 1 with a remainder of 232.
Use 1 as the next digit of our solution. 
Result so far: 44382.70524691
Subtracting 648 from 880 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

The final result is 44382.70524691 with a remainder of 2.32e-07.
