86546686 divided by 240 
The aim is to understand the frequency of 240 in 86546686.

On to step 1:
8 divided by 240 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 240

Moving on to step 2:
240 can be fit into 86 0 times, resulting in a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (5) from the dividend, attach it to 86 and continue: 865 / 240

On to step 3:
The number 240 fits into 865 3 times, leaving a remainder of 145.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 720 from 865, we get 145.
Include the next digit (4) from the dividend after 145, then repeat: 1454 / 240

Advancing to step 4:
When dividing 1454 by 240, we get 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 36.0
If we take 1440 away from 1454, we end up with 14.
Take the next digit (6) from the dividend and append it to 14, then repeat: 146 / 240

Let's proceed to step 5:
240 goes into 146 0 times with a remainder of 146.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Deduct 0 from 146 and we're left with 146.
Append the next digit (6) from the dividend to 146 and continue with: 1466 / 240

Moving on to step 6:
240 can be fit into 1466 6 times, resulting in a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 3606.0
Deduct 1440 from 1466 and we're left with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 240

On to step 7:
240 goes into 268 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 36061.0
If we subtract 240 from 268, we get 28.
Grab the next digit (6) from the dividend, add it to 28, then carry on: 286 / 240

Advancing to step 8:
If we divide 286 by 240, we get 1 and a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 360611.0
Subtracting 240 from 286 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 9:
240 can be fit into 460 1 times, resulting in a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 360611.1
If we take 240 away from 460, we end up with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Moving on to step 10:
2200 divided by 240 is 9 with a remainder of 40.
The next digit of our result is 9. 
Result so far: 360611.19
If we subtract 2160 from 2200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 11:
240 goes into 400 1 times with a remainder of 160.
The number 1 becomes the next digit in our result. 
Result so far: 360611.191
The remainder is 160 after subtracting 240 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 12:
The number 240 fits into 1600 6 times, leaving a remainder of 160.
Write down 6 as next digit of the result. 
Result so far: 360611.1916
If we take 1440 away from 1600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Moving on to step 13:
240 goes into 1600 6 times with a remainder of 160.
Use 6 as the next digit of our solution. 
Result so far: 360611.19166
If we take 1440 away from 1600, we end up with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 360611.19166 with a remainder of 0.00016.
