We divide 81581708 by 240
The aim is to understand the frequency of 240 in 81581708.

Moving on to step 1:
If we divide 8 by 240, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 240

Moving on to step 2:
The number 240 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Grab the next digit (5) from the dividend, add it to 81, then carry on: 815 / 240

Advancing to step 3:
240 can be fit into 815 3 times, resulting in a remainder of 95.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 720 from 815 leaves us with 95.
Bring next digit (8) of the dividend behind the 95 and repeat the process: 958 / 240

On to step 4:
The number 240 fits into 958 3 times, leaving a remainder of 238.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
Deduct 720 from 958 and we're left with 238.
Bring next digit (1) of the dividend behind the 238 and repeat the process: 2381 / 240

Going ahead to step 5:
The number 240 fits into 2381 9 times, leaving a remainder of 221.
The next digit of our result is 9. 
Result so far: 339.0
If we take 2160 away from 2381, we end up with 221.
Take the next digit (7) from the dividend and append it to 221, then repeat: 2217 / 240

Moving on to step 6:
The number 240 fits into 2217 9 times, leaving a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 3399.0
Subtracting 2160 from 2217 leaves us with 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 240

Going ahead to step 7:
240 can be fit into 570 2 times, resulting in a remainder of 90.
Record the quotient 2 as the next digit in the result. 
Result so far: 33992.0
Deduct 480 from 570 and we're left with 90.
Bring next digit (8) of the dividend behind the 90 and repeat the process: 908 / 240

On to step 8:
If we divide 908 by 240, we get 3 and a remainder of 188.
The number 3 becomes the next digit in our result. 
Result so far: 339923.0
Subtracting 720 from 908 leaves us with 188.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Moving on to step 9:
If we divide 1880 by 240, we get 7 and a remainder of 200.
Record the quotient 7 as the next digit in the result. 
Result so far: 339923.7
If we take 1680 away from 1880, we end up 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.

On to step 10:
240 can be fit into 2000 8 times, resulting in a remainder of 80.
The number 8 becomes the next digit in our result. 
Result so far: 339923.78
If we subtract 1920 from 2000, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 11:
240 goes into 800 3 times with a remainder of 80.
The next digit of our result is 3. 
Result so far: 339923.783
Deduct 720 from 800 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.

Going ahead to step 12:
240 goes into 800 3 times with a remainder of 80.
Put 3 as the next digit of the answer. 
Result so far: 339923.7833
Subtracting 720 from 800 leaves us 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.

The final result is 339923.7833 with a remainder of 0.0008.
