653505 ÷ 86 
The aim is to understand the frequency of 86 in 653505.

Step 1:
If we divide 6 by 86, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (5) of the dividend behind the 6 and repeat the process: 65 / 86

Step 2:
If we divide 65 by 86, we get 0 and a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Fetch the next digit (3) from the dividend, attach it to 65 and continue: 653 / 86

Let's proceed to step 3:
86 can be fit into 653 7 times, resulting in a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 602 away from 653, we end up with 51.
Include the next digit (5) from the dividend after 51, then repeat: 515 / 86

Let's proceed to step 4:
86 can be fit into 515 5 times, resulting in a remainder of 85.
Write down 5 as next digit of the result. 
Result so far: 75.0
If we subtract 430 from 515, we get 85.
Append the next digit (0) from the dividend to 85 and continue with: 850 / 86

Moving on to step 5:
850 divided by 86 is 9 with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 759.0
Deduct 774 from 850 and we're left with 76.
Grab the next digit (5) from the dividend, add it to 76, then carry on: 765 / 86

Going ahead to step 6:
If we divide 765 by 86, we get 8 and a remainder of 77.
Use 8 as the next digit of our solution. 
Result so far: 7598.0
Deduct 688 from 765 and we're left 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.

Moving on to step 7:
If we divide 770 by 86, we get 8 and a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 7598.8
Subtracting 688 from 770 leaves us with 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:
86 goes into 820 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 7598.89
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.

Step 9:
When dividing 460 by 86, we get 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 7598.895
Subtracting 430 from 460 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 10:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 7598.8953
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.

On to step 11:
If we divide 420 by 86, we get 4 and a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 7598.89534
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:
760 divided by 86 is 8 with a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 7598.895348
Subtract 688 from 760 to get 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 13:
720 divided by 86 is 8 with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 7598.8953488
If we subtract 688 from 720, we 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 7598.8953488, with a leftover of 3.2e-07.
