81786876 ÷ 247 
The aim is to understand the frequency of 247 in 81786876.

Moving on to step 1:
247 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 247

Advancing to step 2:
247 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Append the next digit (7) from the dividend to 81 and continue with: 817 / 247

Moving on to step 3:
817 divided by 247 is 3 with a remainder of 76.
The next digit of our result is 3. 
Result so far: 3.0
If we take 741 away from 817, we end up with 76.
Include the next digit (8) from the dividend after 76, then repeat: 768 / 247

Going ahead to step 4:
768 divided by 247 is 3 with a remainder of 27.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 741 from 768, we get 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 247

Moving on to step 5:
If we divide 276 by 247, we get 1 and a remainder of 29.
Write down 1 as next digit of the result. 
Result so far: 331.0
If we subtract 247 from 276, we get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 247

On to step 6:
298 divided by 247 is 1 with a remainder of 51.
Record the quotient 1 as the next digit in the result. 
Result so far: 3311.0
Subtracting 247 from 298 leaves us with 51.
Bring next digit (7) of the dividend behind the 51 and repeat the process: 517 / 247

Moving on to step 7:
If we divide 517 by 247, we get 2 and a remainder of 23.
The number 2 becomes the next digit in our result. 
Result so far: 33112.0
Deduct 494 from 517 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 247

Advancing to step 8:
247 goes into 236 0 times with a remainder of 236.
The number 0 becomes the next digit in our result. 
Result so far: 331120.0
If we take 0 away from 236, we end up with 236.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2360, and continue the process.

On to step 9:
If we divide 2360 by 247, we get 9 and a remainder of 137.
The next digit of our result is 9. 
Result so far: 331120.9
Subtract 2223 from 2360 to get 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Step 10:
247 goes into 1370 5 times with a remainder of 135.
The number 5 becomes the next digit in our result. 
Result so far: 331120.95
Deduct 1235 from 1370 and we're left with 135.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

Let's proceed to step 11:
The number 247 fits into 1350 5 times, leaving a remainder of 115.
Put 5 as the next digit of the answer. 
Result so far: 331120.955
The remainder is 115 after subtracting 1235 from 1350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

The final outcome is 331120.955, with a leftover of 0.0115.
