69804 ÷ 86 
The aim is to understand the frequency of 86 in 69804.

On to step 1:
6 divided by 86 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 86

Moving on to step 2:
86 can be fit into 69 0 times, resulting in a remainder of 69.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 69 and we're left with 69.
Include the next digit (8) from the dividend after 69, then repeat: 698 / 86

Going ahead to step 3:
86 goes into 698 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 8.0
If we subtract 688 from 698, we get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 86

On to step 4:
86 goes into 100 1 times with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 81.0
Subtract 86 from 100 to get 14.
Append the next digit (4) from the dividend to 14 and continue with: 144 / 86

Step 5:
86 goes into 144 1 times with a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 811.0
If we take 86 away from 144, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 6:
86 goes into 580 6 times with a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 811.6
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 7:
640 divided by 86 is 7 with a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 811.67
If we subtract 602 from 640, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 8:
The number 86 fits into 380 4 times, leaving a remainder of 36.
The next digit of our result is 4. 
Result so far: 811.674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 9:
86 goes into 360 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 811.6744
If we take 344 away from 360, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Our division results in 811.6744 with a remaining 0.00016.
