18342211 divided by 648 
We're looking to find how many times 648 goes into 18342211.

On to step 1:
648 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 648

Step 2:
648 can be fit into 18 0 times, resulting in a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 648

On to step 3:
648 goes into 183 0 times with a remainder of 183.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 183 and we're left with 183.
Grab the next digit (4) from the dividend, add it to 183, then carry on: 1834 / 648

Advancing to step 4:
648 can be fit into 1834 2 times, resulting in a remainder of 538.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1296 from 1834, we get 538.
Grab the next digit (2) from the dividend, add it to 538, then carry on: 5382 / 648

Let's proceed to step 5:
The number 648 fits into 5382 8 times, leaving a remainder of 198.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Subtract 5184 from 5382 to get 198.
Bring next digit (2) of the dividend behind the 198 and repeat the process: 1982 / 648

Advancing to step 6:
1982 divided by 648 is 3 with a remainder of 38.
Write down 3 as next digit of the result. 
Result so far: 283.0
If we subtract 1944 from 1982, we get 38.
Take the next digit (1) from the dividend and append it to 38, then repeat: 381 / 648

Moving on to step 7:
381 divided by 648 is 0 with a remainder of 381.
The next digit of our result is 0. 
Result so far: 2830.0
Subtracting 0 from 381 leaves us with 381.
Include the next digit (1) from the dividend after 381, then repeat: 3811 / 648

On to step 8:
When dividing 3811 by 648, we get 5 with a remainder of 571.
The number 5 becomes the next digit in our result. 
Result so far: 28305.0
Subtracting 3240 from 3811 leaves us with 571.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5710, and continue the process.

Moving on to step 9:
5710 divided by 648 is 8 with a remainder of 526.
Put 8 as the next digit of the answer. 
Result so far: 28305.8
The remainder is 526 after subtracting 5184 from 5710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5260, and continue the process.

Moving on to step 10:
The number 648 fits into 5260 8 times, leaving a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 28305.88
Subtract 5184 from 5260 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 28305.88 with a remainder of 0.076.
