We look at the division of 81181266 by 240 
The aim is to understand the frequency of 240 in 81181266.

On to step 1:
The number 240 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 240

Let's proceed to step 2:
When dividing 81 by 240, we get 0 with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Fetch the next digit (1) from the dividend, attach it to 81 and continue: 811 / 240

Advancing to step 3:
240 goes into 811 3 times with a remainder of 91.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 91 after subtracting 720 from 811.
Include the next digit (8) from the dividend after 91, then repeat: 918 / 240

Going ahead to step 4:
918 divided by 240 is 3 with a remainder of 198.
Put 3 as the next digit of the answer. 
Result so far: 33.0
If we take 720 away from 918, we end up with 198.
Bring next digit (1) of the dividend behind the 198 and repeat the process: 1981 / 240

On to step 5:
When dividing 1981 by 240, we get 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 338.0
Deduct 1920 from 1981 and we're left with 61.
Bring next digit (2) of the dividend behind the 61 and repeat the process: 612 / 240

Advancing to step 6:
240 goes into 612 2 times with a remainder of 132.
Record the quotient 2 as the next digit in the result. 
Result so far: 3382.0
Subtract 480 from 612 to get 132.
Grab the next digit (6) from the dividend, add it to 132, then carry on: 1326 / 240

Advancing to step 7:
240 can be fit into 1326 5 times, resulting in a remainder of 126.
The next digit of our result is 5. 
Result so far: 33825.0
If we subtract 1200 from 1326, we get 126.
Bring next digit (6) of the dividend behind the 126 and repeat the process: 1266 / 240

On to step 8:
If we divide 1266 by 240, we get 5 and a remainder of 66.
The number 5 becomes the next digit in our result. 
Result so far: 338255.0
If we take 1200 away from 1266, we end up with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 9:
If we divide 660 by 240, we get 2 and a remainder of 180.
Put 2 as the next digit of the answer. 
Result so far: 338255.2
If we subtract 480 from 660, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 10:
If we divide 1800 by 240, we get 7 and a remainder of 120.
Write down 7 as next digit of the result. 
Result so far: 338255.27
If we take 1680 away from 1800, we end up 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.

Moving on to step 11:
When dividing 1200 by 240, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 338255.275
If we subtract 1200 from 1200, we 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.

Advancing to step 12:
0 divided by 240 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 338255.275
If we take 0 away from 0, we end up 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.

Let's proceed to step 13:
240 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 338255.275
If we subtract 0 from 0, we 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.

After the division, we end up with 338255.275 and a remainder of 0.0.
