We're dividing 40305553 by 648 
We want to divide 40305553 by 648.

Going ahead to step 1:
If we divide 4 by 648, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 648

Moving on to step 2:
When dividing 40 by 648, we get 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 648

Advancing to step 3:
If we divide 403 by 648, we get 0 and a remainder of 403.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 403, we get 403.
Bring next digit (0) of the dividend behind the 403 and repeat the process: 4030 / 648

On to step 4:
The number 648 fits into 4030 6 times, leaving a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 3888 from 4030 leaves us with 142.
Fetch the next digit (5) from the dividend, attach it to 142 and continue: 1425 / 648

Advancing to step 5:
1425 divided by 648 is 2 with a remainder of 129.
Write down 2 as next digit of the result. 
Result so far: 62.0
If we take 1296 away from 1425, we end up with 129.
Take the next digit (5) from the dividend and append it to 129, then repeat: 1295 / 648

Step 6:
When dividing 1295 by 648, we get 1 with a remainder of 647.
Record the quotient 1 as the next digit in the result. 
Result so far: 621.0
Deduct 648 from 1295 and we're left with 647.
Bring next digit (5) of the dividend behind the 647 and repeat the process: 6475 / 648

Going ahead to step 7:
6475 divided by 648 is 9 with a remainder of 643.
The number 9 becomes the next digit in our result. 
Result so far: 6219.0
If we subtract 5832 from 6475, we get 643.
Fetch the next digit (3) from the dividend, attach it to 643 and continue: 6433 / 648

Advancing to step 8:
The number 648 fits into 6433 9 times, leaving a remainder of 601.
Write down 9 as next digit of the result. 
Result so far: 62199.0
Subtracting 5832 from 6433 leaves us with 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Going ahead to step 9:
The number 648 fits into 6010 9 times, leaving a remainder of 178.
Record the quotient 9 as the next digit in the result. 
Result so far: 62199.9
Subtract 5832 from 6010 to get 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

On to step 10:
648 goes into 1780 2 times with a remainder of 484.
Write down 2 as next digit of the result. 
Result so far: 62199.92
If we take 1296 away from 1780, we end up with 484.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4840, and continue the process.

Moving on to step 11:
The number 648 fits into 4840 7 times, leaving a remainder of 304.
Record the quotient 7 as the next digit in the result. 
Result so far: 62199.927
The remainder is 304 after subtracting 4536 from 4840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Let's proceed to step 12:
If we divide 3040 by 648, we get 4 and a remainder of 448.
The number 4 becomes the next digit in our result. 
Result so far: 62199.9274
If we subtract 2592 from 3040, we get 448.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Moving on to step 13:
4480 divided by 648 is 6 with a remainder of 592.
Record the quotient 6 as the next digit in the result. 
Result so far: 62199.92746
The remainder is 592 after subtracting 3888 from 4480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5920, and continue the process.

Step 14:
When dividing 5920 by 648, we get 9 with a remainder of 88.
The next digit of our result is 9. 
Result so far: 62199.927469
Subtracting 5832 from 5920 leaves us with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 15:
648 goes into 880 1 times with a remainder of 232.
The number 1 becomes the next digit in our result. 
Result so far: 62199.9274691
The remainder is 232 after subtracting 648 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Going ahead to step 16:
When dividing 2320 by 648, we get 3 with a remainder of 376.
The next digit of our result is 3. 
Result so far: 62199.92746913
If we take 1944 away from 2320, we end up with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Our division results in 62199.92746913 with a remaining 3.76e-07.
