52009495 ÷ 648 
We want to divide 52009495 by 648.

Advancing to step 1:
If we divide 5 by 648, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 648

On to step 2:
648 goes into 52 0 times with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 648

On to step 3:
When dividing 520 by 648, we get 0 with a remainder of 520.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 520 after subtracting 0 from 520.
Bring next digit (0) of the dividend behind the 520 and repeat the process: 5200 / 648

Moving on to step 4:
5200 divided by 648 is 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 5184 away from 5200, we end up with 16.
Grab the next digit (9) from the dividend, add it to 16, then carry on: 169 / 648

Going ahead to step 5:
648 goes into 169 0 times with a remainder of 169.
Use 0 as the next digit of our solution. 
Result so far: 80.0
If we take 0 away from 169, we end up with 169.
Include the next digit (4) from the dividend after 169, then repeat: 1694 / 648

Going ahead to step 6:
648 can be fit into 1694 2 times, resulting in a remainder of 398.
Write down 2 as next digit of the result. 
Result so far: 802.0
Subtracting 1296 from 1694 leaves us with 398.
Include the next digit (9) from the dividend after 398, then repeat: 3989 / 648

On to step 7:
648 goes into 3989 6 times with a remainder of 101.
Put 6 as the next digit of the answer. 
Result so far: 8026.0
Deduct 3888 from 3989 and we're left with 101.
Fetch the next digit (5) from the dividend, attach it to 101 and continue: 1015 / 648

Step 8:
When dividing 1015 by 648, we get 1 with a remainder of 367.
Record the quotient 1 as the next digit in the result. 
Result so far: 80261.0
Subtracting 648 from 1015 leaves us with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

Moving on to step 9:
648 goes into 3670 5 times with a remainder of 430.
The number 5 becomes the next digit in our result. 
Result so far: 80261.5
Subtracting 3240 from 3670 leaves us with 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4300, and continue the process.

Moving on to step 10:
The number 648 fits into 4300 6 times, leaving a remainder of 412.
Put 6 as the next digit of the answer. 
Result so far: 80261.56
The remainder is 412 after subtracting 3888 from 4300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4120, and continue the process.

Moving on to step 11:
When dividing 4120 by 648, we get 6 with a remainder of 232.
The number 6 becomes the next digit in our result. 
Result so far: 80261.566
The remainder is 232 after subtracting 3888 from 4120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

In conclusion, the division gives 80261.566 with a balance of 0.0232.
