We look at the division of 63411045 by 648 
Our goal is to divide 63411045 by 648.

On to step 1:
648 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 648

Going ahead to step 2:
If we divide 63 by 648, we get 0 and a remainder of 63.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 63 to get 63.
Append the next digit (4) from the dividend to 63 and continue with: 634 / 648

Moving on to step 3:
If we divide 634 by 648, we get 0 and a remainder of 634.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 634, we get 634.
Take the next digit (1) from the dividend and append it to 634, then repeat: 6341 / 648

Step 4:
6341 divided by 648 is 9 with a remainder of 509.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 5832 from 6341, we get 509.
Take the next digit (1) from the dividend and append it to 509, then repeat: 5091 / 648

Going ahead to step 5:
648 goes into 5091 7 times with a remainder of 555.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 4536 from 5091, we get 555.
Bring next digit (0) of the dividend behind the 555 and repeat the process: 5550 / 648

Going ahead to step 6:
648 can be fit into 5550 8 times, resulting in a remainder of 366.
The number 8 becomes the next digit in our result. 
Result so far: 978.0
Subtract 5184 from 5550 to get 366.
Grab the next digit (4) from the dividend, add it to 366, then carry on: 3664 / 648

Step 7:
3664 divided by 648 is 5 with a remainder of 424.
The number 5 becomes the next digit in our result. 
Result so far: 9785.0
The remainder is 424 after subtracting 3240 from 3664.
Include the next digit (5) from the dividend after 424, then repeat: 4245 / 648

Advancing to step 8:
648 can be fit into 4245 6 times, resulting in a remainder of 357.
The next digit of our result is 6. 
Result so far: 97856.0
Deduct 3888 from 4245 and we're left with 357.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3570, and continue the process.

Moving on to step 9:
3570 divided by 648 is 5 with a remainder of 330.
Write down 5 as next digit of the result. 
Result so far: 97856.5
If we take 3240 away from 3570, we end up with 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3300, and continue the process.

Step 10:
648 can be fit into 3300 5 times, resulting in a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 97856.55
Subtract 3240 from 3300 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

After the division, we end up with 97856.55 and a remainder of 0.06.
