We divide 81815924 by 240
We want to figure out the number of times 81815924 can be divided by 240.

Advancing to step 1:
When dividing 8 by 240, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 240

Moving on to step 2:
The number 240 fits into 81 0 times, leaving a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (8) from the dividend, attach it to 81 and continue: 818 / 240

Advancing to step 3:
When dividing 818 by 240, we get 3 with a remainder of 98.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 98 after subtracting 720 from 818.
Grab the next digit (1) from the dividend, add it to 98, then carry on: 981 / 240

Moving on to step 4:
When dividing 981 by 240, we get 4 with a remainder of 21.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 960 from 981 and we're left with 21.
Fetch the next digit (5) from the dividend, attach it to 21 and continue: 215 / 240

Let's proceed to step 5:
240 goes into 215 0 times with a remainder of 215.
Put 0 as the next digit of the answer. 
Result so far: 340.0
The remainder is 215 after subtracting 0 from 215.
Bring next digit (9) of the dividend behind the 215 and repeat the process: 2159 / 240

Moving on to step 6:
240 can be fit into 2159 8 times, resulting in a remainder of 239.
Record the quotient 8 as the next digit in the result. 
Result so far: 3408.0
If we subtract 1920 from 2159, we get 239.
Include the next digit (2) from the dividend after 239, then repeat: 2392 / 240

Let's proceed to step 7:
If we divide 2392 by 240, we get 9 and a remainder of 232.
Record the quotient 9 as the next digit in the result. 
Result so far: 34089.0
If we take 2160 away from 2392, we end up with 232.
Include the next digit (4) from the dividend after 232, then repeat: 2324 / 240

Let's proceed to step 8:
240 can be fit into 2324 9 times, resulting in a remainder of 164.
Write down 9 as next digit of the result. 
Result so far: 340899.0
If we take 2160 away from 2324, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Let's proceed to step 9:
The number 240 fits into 1640 6 times, leaving a remainder of 200.
Put 6 as the next digit of the answer. 
Result so far: 340899.6
Subtracting 1440 from 1640 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Moving on to step 10:
240 can be fit into 2000 8 times, resulting in a remainder of 80.
Record the quotient 8 as the next digit in the result. 
Result so far: 340899.68
Deduct 1920 from 2000 and we're left with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
When dividing 800 by 240, we get 3 with a remainder of 80.
Record the quotient 3 as the next digit in the result. 
Result so far: 340899.683
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 12:
240 can be fit into 800 3 times, resulting in a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 340899.6833
The remainder is 80 after subtracting 720 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

The final result is 340899.6833 with a remainder of 0.0008.
