56239017 ÷ 648 
We want to figure out the number of times 56239017 can be divided by 648.

Let's proceed to step 1:
If we divide 5 by 648, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (6) of the dividend behind the 5 and repeat the process: 56 / 648

Moving on to step 2:
56 divided by 648 is 0 with a remainder of 56.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 56, we get 56.
Take the next digit (2) from the dividend and append it to 56, then repeat: 562 / 648

Advancing to step 3:
648 can be fit into 562 0 times, resulting in a remainder of 562.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 562, we end up with 562.
Fetch the next digit (3) from the dividend, attach it to 562 and continue: 5623 / 648

Let's proceed to step 4:
5623 divided by 648 is 8 with a remainder of 439.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 5184 from 5623 to get 439.
Include the next digit (9) from the dividend after 439, then repeat: 4399 / 648

Let's proceed to step 5:
648 goes into 4399 6 times with a remainder of 511.
The next digit of our result is 6. 
Result so far: 86.0
If we subtract 3888 from 4399, we get 511.
Bring next digit (0) of the dividend behind the 511 and repeat the process: 5110 / 648

On to step 6:
648 goes into 5110 7 times with a remainder of 574.
The next digit of our result is 7. 
Result so far: 867.0
If we subtract 4536 from 5110, we get 574.
Bring next digit (1) of the dividend behind the 574 and repeat the process: 5741 / 648

On to step 7:
When dividing 5741 by 648, we get 8 with a remainder of 557.
Record the quotient 8 as the next digit in the result. 
Result so far: 8678.0
If we take 5184 away from 5741, we end up with 557.
Include the next digit (7) from the dividend after 557, then repeat: 5577 / 648

Let's proceed to step 8:
648 goes into 5577 8 times with a remainder of 393.
The number 8 becomes the next digit in our result. 
Result so far: 86788.0
If we take 5184 away from 5577, we end up with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

Advancing to step 9:
The number 648 fits into 3930 6 times, leaving a remainder of 42.
Write down 6 as next digit of the result. 
Result so far: 86788.6
Subtracting 3888 from 3930 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 10:
If we divide 420 by 648, we get 0 and a remainder of 420.
The next digit of our result is 0. 
Result so far: 86788.6
Subtract 0 from 420 to get 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Moving on to step 11:
The number 648 fits into 4200 6 times, leaving a remainder of 312.
The number 6 becomes the next digit in our result. 
Result so far: 86788.606
The remainder is 312 after subtracting 3888 from 4200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

On to step 12:
3120 divided by 648 is 4 with a remainder of 528.
The next digit of our result is 4. 
Result so far: 86788.6064
Deduct 2592 from 3120 and we're left with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 13:
648 goes into 5280 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 86788.60648
If we subtract 5184 from 5280, we get 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

On to step 14:
648 goes into 960 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 86788.606481
Subtract 648 from 960 to get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

Advancing to step 15:
The number 648 fits into 3120 4 times, leaving a remainder of 528.
Write down 4 as next digit of the result. 
Result so far: 86788.6064814
The remainder is 528 after subtracting 2592 from 3120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Going ahead to step 16:
648 goes into 5280 8 times with a remainder of 96.
Write down 8 as next digit of the result. 
Result so far: 86788.60648148
The remainder is 96 after subtracting 5184 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

In conclusion, the division gives 86788.60648148 with a balance of 9.6e-08.
