Let's divide 21618810 by 240
We want to figure out the number of times 21618810 can be divided by 240.

Let's proceed to step 1:
240 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 240

Advancing to step 2:
240 can be fit into 21 0 times, resulting in a remainder of 21.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 240

Moving on to step 3:
If we divide 216 by 240, we get 0 and a remainder of 216.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 216, we end up with 216.
Fetch the next digit (1) from the dividend, attach it to 216 and continue: 2161 / 240

Step 4:
If we divide 2161 by 240, we get 9 and a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 2160 from 2161 leaves us with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 240

On to step 5:
240 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 90.0
Subtract 0 from 18 to get 18.
Fetch the next digit (8) from the dividend, attach it to 18 and continue: 188 / 240

Going ahead to step 6:
240 can be fit into 188 0 times, resulting in a remainder of 188.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
Deduct 0 from 188 and we're left with 188.
Fetch the next digit (1) from the dividend, attach it to 188 and continue: 1881 / 240

On to step 7:
When dividing 1881 by 240, we get 7 with a remainder of 201.
The next digit of our result is 7. 
Result so far: 9007.0
Subtract 1680 from 1881 to get 201.
Include the next digit (0) from the dividend after 201, then repeat: 2010 / 240

Going ahead to step 8:
When dividing 2010 by 240, we get 8 with a remainder of 90.
The next digit of our result is 8. 
Result so far: 90078.0
If we subtract 1920 from 2010, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 9:
The number 240 fits into 900 3 times, leaving a remainder of 180.
Put 3 as the next digit of the answer. 
Result so far: 90078.3
Deduct 720 from 900 and we're left with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 10:
1800 divided by 240 is 7 with a remainder of 120.
Put 7 as the next digit of the answer. 
Result so far: 90078.37
Subtracting 1680 from 1800 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
240 goes into 1200 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 90078.375
Deduct 1200 from 1200 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 12:
If we divide 0 by 240, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 90078.375
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 13:
If we divide 0 by 240, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 90078.375
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 90078.375 with a balance of 0.0.
