587650 divided by 86 
The aim is to understand the frequency of 86 in 587650.

Step 1:
If we divide 5 by 86, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 86

Let's proceed to step 2:
When dividing 58 by 86, we get 0 with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Fetch the next digit (7) from the dividend, attach it to 58 and continue: 587 / 86

On to step 3:
86 goes into 587 6 times with a remainder of 71.
Write down 6 as next digit of the result. 
Result so far: 6.0
Subtracting 516 from 587 leaves us with 71.
Fetch the next digit (6) from the dividend, attach it to 71 and continue: 716 / 86

On to step 4:
When dividing 716 by 86, we get 8 with a remainder of 28.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 688 from 716, we get 28.
Fetch the next digit (5) from the dividend, attach it to 28 and continue: 285 / 86

Advancing to step 5:
285 divided by 86 is 3 with a remainder of 27.
The next digit of our result is 3. 
Result so far: 683.0
If we take 258 away from 285, we end up with 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 86

Advancing to step 6:
The number 86 fits into 270 3 times, leaving a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 6833.0
Subtract 258 from 270 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 7:
86 can be fit into 120 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 6833.1
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 8:
When dividing 340 by 86, we get 3 with a remainder of 82.
The number 3 becomes the next digit in our result. 
Result so far: 6833.13
The remainder is 82 after subtracting 258 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 9:
86 goes into 820 9 times with a remainder of 46.
The next digit of our result is 9. 
Result so far: 6833.139
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.

On to step 10:
If we divide 460 by 86, we get 5 and a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 6833.1395
If we subtract 430 from 460, we 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 11:
When dividing 300 by 86, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 6833.13953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 12:
86 goes into 420 4 times with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 6833.139534
Subtracting 344 from 420 leaves us with 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 13:
760 divided by 86 is 8 with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 6833.1395348
If we take 688 away from 760, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
86 goes into 720 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 6833.13953488
Subtracting 688 from 720 leaves us with 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 6833.13953488, with a leftover of 3.2e-08.
