We look at the division of 3155047 by 648 
Let's see how many times 648 fits into 3155047.

Going ahead to step 1:
3 divided by 648 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 648

Advancing to step 2:
648 can be fit into 31 0 times, resulting in a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 31 and we're left with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 648

Moving on to step 3:
648 can be fit into 315 0 times, resulting in a remainder of 315.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 315 after subtracting 0 from 315.
Fetch the next digit (5) from the dividend, attach it to 315 and continue: 3155 / 648

Advancing to step 4:
3155 divided by 648 is 4 with a remainder of 563.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2592 from 3155 to get 563.
Include the next digit (0) from the dividend after 563, then repeat: 5630 / 648

Going ahead to step 5:
When dividing 5630 by 648, we get 8 with a remainder of 446.
Put 8 as the next digit of the answer. 
Result so far: 48.0
If we subtract 5184 from 5630, we get 446.
Grab the next digit (4) from the dividend, add it to 446, then carry on: 4464 / 648

On to step 6:
4464 divided by 648 is 6 with a remainder of 576.
The next digit of our result is 6. 
Result so far: 486.0
Subtracting 3888 from 4464 leaves us with 576.
Bring next digit (7) of the dividend behind the 576 and repeat the process: 5767 / 648

Going ahead to step 7:
The number 648 fits into 5767 8 times, leaving a remainder of 583.
Put 8 as the next digit of the answer. 
Result so far: 4868.0
Deduct 5184 from 5767 and we're left with 583.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5830, and continue the process.

Advancing to step 8:
648 can be fit into 5830 8 times, resulting in a remainder of 646.
The number 8 becomes the next digit in our result. 
Result so far: 4868.8
If we take 5184 away from 5830, we end up with 646.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6460, and continue the process.

Moving on to step 9:
648 goes into 6460 9 times with a remainder of 628.
Record the quotient 9 as the next digit in the result. 
Result so far: 4868.89
The remainder is 628 after subtracting 5832 from 6460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6280, and continue the process.

Moving on to step 10:
6280 divided by 648 is 9 with a remainder of 448.
Use 9 as the next digit of our solution. 
Result so far: 4868.899
If we subtract 5832 from 6280, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

The final result is 4868.899 with a remainder of 0.0448.
