65572341 ÷ 648 
We want to divide 65572341 by 648.

Advancing to step 1:
648 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 648

On to step 2:
65 divided by 648 is 0 with a remainder of 65.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Take the next digit (5) from the dividend and append it to 65, then repeat: 655 / 648

Advancing to step 3:
655 divided by 648 is 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 648 from 655 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 648

Going ahead to step 4:
648 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 77 and we're left with 77.
Grab the next digit (2) from the dividend, add it to 77, then carry on: 772 / 648

Going ahead to step 5:
The number 648 fits into 772 1 times, leaving a remainder of 124.
The next digit of our result is 1. 
Result so far: 101.0
If we take 648 away from 772, we end up with 124.
Grab the next digit (3) from the dividend, add it to 124, then carry on: 1243 / 648

Going ahead to step 6:
When dividing 1243 by 648, we get 1 with a remainder of 595.
The number 1 becomes the next digit in our result. 
Result so far: 1011.0
Subtract 648 from 1243 to get 595.
Bring next digit (4) of the dividend behind the 595 and repeat the process: 5954 / 648

Going ahead to step 7:
If we divide 5954 by 648, we get 9 and a remainder of 122.
Put 9 as the next digit of the answer. 
Result so far: 10119.0
Subtract 5832 from 5954 to get 122.
Bring next digit (1) of the dividend behind the 122 and repeat the process: 1221 / 648

Step 8:
648 goes into 1221 1 times with a remainder of 573.
Write down 1 as next digit of the result. 
Result so far: 101191.0
Subtracting 648 from 1221 leaves us with 573.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5730, and continue the process.

Step 9:
The number 648 fits into 5730 8 times, leaving a remainder of 546.
The next digit of our result is 8. 
Result so far: 101191.8
If we take 5184 away from 5730, we end up with 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Advancing to step 10:
648 can be fit into 5460 8 times, resulting in a remainder of 276.
Write down 8 as next digit of the result. 
Result so far: 101191.88
Subtract 5184 from 5460 to get 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

After the division, we end up with 101191.88 and a remainder of 0.276.
