We look at the division of 45072996 by 648 
We want to divide 45072996 by 648.

Step 1:
648 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 648

Step 2:
The number 648 fits into 45 0 times, leaving a remainder of 45.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 45, we end up with 45.
Include the next digit (0) from the dividend after 45, then repeat: 450 / 648

On to step 3:
When dividing 450 by 648, we get 0 with a remainder of 450.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 450, we get 450.
Bring next digit (7) of the dividend behind the 450 and repeat the process: 4507 / 648

Going ahead to step 4:
648 goes into 4507 6 times with a remainder of 619.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 3888 from 4507 to get 619.
Append the next digit (2) from the dividend to 619 and continue with: 6192 / 648

Step 5:
648 goes into 6192 9 times with a remainder of 360.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
The remainder is 360 after subtracting 5832 from 6192.
Bring next digit (9) of the dividend behind the 360 and repeat the process: 3609 / 648

Let's proceed to step 6:
648 can be fit into 3609 5 times, resulting in a remainder of 369.
Write down 5 as next digit of the result. 
Result so far: 695.0
If we take 3240 away from 3609, we end up with 369.
Bring next digit (9) of the dividend behind the 369 and repeat the process: 3699 / 648

Moving on to step 7:
648 can be fit into 3699 5 times, resulting in a remainder of 459.
Put 5 as the next digit of the answer. 
Result so far: 6955.0
The remainder is 459 after subtracting 3240 from 3699.
Bring next digit (6) of the dividend behind the 459 and repeat the process: 4596 / 648

Advancing to step 8:
The number 648 fits into 4596 7 times, leaving a remainder of 60.
Put 7 as the next digit of the answer. 
Result so far: 69557.0
If we take 4536 away from 4596, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 9:
600 divided by 648 is 0 with a remainder of 600.
Use 0 as the next digit of our solution. 
Result so far: 69557.0
If we take 0 away from 600, we end up with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Let's proceed to step 10:
648 can be fit into 6000 9 times, resulting in a remainder of 168.
The next digit of our result is 9. 
Result so far: 69557.09
Deduct 5832 from 6000 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Advancing to step 11:
1680 divided by 648 is 2 with a remainder of 384.
Write down 2 as next digit of the result. 
Result so far: 69557.092
If we take 1296 away from 1680, we end up with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Moving on to step 12:
648 can be fit into 3840 5 times, resulting in a remainder of 600.
The number 5 becomes the next digit in our result. 
Result so far: 69557.0925
Subtracting 3240 from 3840 leaves us with 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Step 13:
The number 648 fits into 6000 9 times, leaving a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 69557.09259
Deduct 5832 from 6000 and we're left with 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 14:
648 can be fit into 1680 2 times, resulting in a remainder of 384.
The next digit of our result is 2. 
Result so far: 69557.092592
Deduct 1296 from 1680 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Advancing to step 15:
If we divide 3840 by 648, we get 5 and a remainder of 600.
Put 5 as the next digit of the answer. 
Result so far: 69557.0925925
Subtract 3240 from 3840 to get 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6000, and continue the process.

Going ahead to step 16:
648 goes into 6000 9 times with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 69557.09259259
Subtract 5832 from 6000 to get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Our division results in 69557.09259259 with a remaining 1.68e-07.
