777775 divided by 86 
The aim is to understand the frequency of 86 in 777775.

Going ahead to step 1:
The number 86 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 86

Advancing to step 2:
77 divided by 86 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 86

Step 3:
When dividing 777 by 86, we get 9 with a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 774 from 777 and we're left with 3.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 86

Moving on to step 4:
If we divide 37 by 86, we get 0 and a remainder of 37.
Use 0 as the next digit of our solution. 
Result so far: 90.0
If we take 0 away from 37, we end up with 37.
Grab the next digit (7) from the dividend, add it to 37, then carry on: 377 / 86

Let's proceed to step 5:
86 goes into 377 4 times with a remainder of 33.
Record the quotient 4 as the next digit in the result. 
Result so far: 904.0
The remainder is 33 after subtracting 344 from 377.
Append the next digit (5) from the dividend to 33 and continue with: 335 / 86

On to step 6:
86 goes into 335 3 times with a remainder of 77.
The next digit of our result is 3. 
Result so far: 9043.0
If we take 258 away from 335, we end up with 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Advancing to step 7:
The number 86 fits into 770 8 times, leaving a remainder of 82.
Record the quotient 8 as the next digit in the result. 
Result so far: 9043.8
Subtract 688 from 770 to get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Let's proceed to step 8:
820 divided by 86 is 9 with a remainder of 46.
Use 9 as the next digit of our solution. 
Result so far: 9043.89
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 9:
460 divided by 86 is 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 9043.895
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
86 can be fit into 300 3 times, resulting in a remainder of 42.
The number 3 becomes the next digit in our result. 
Result so far: 9043.8953
Deduct 258 from 300 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
420 divided by 86 is 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 9043.89534
If we subtract 344 from 420, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 12:
If we divide 760 by 86, we get 8 and a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 9043.895348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 13:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 9043.8953488
Subtract 688 from 720 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 9043.8953488, with a leftover of 3.2e-07.
