825535 divided by 84 
The aim is to understand the frequency of 84 in 825535.

Let's proceed to step 1:
8 divided by 84 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 84

Let's proceed to step 2:
82 divided by 84 is 0 with a remainder of 82.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 82 after subtracting 0 from 82.
Append the next digit (5) from the dividend to 82 and continue with: 825 / 84

Step 3:
When dividing 825 by 84, we get 9 with a remainder of 69.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 756 from 825 and we're left with 69.
Append the next digit (5) from the dividend to 69 and continue with: 695 / 84

On to step 4:
84 can be fit into 695 8 times, resulting in a remainder of 23.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 672 from 695 leaves us with 23.
Bring next digit (3) of the dividend behind the 23 and repeat the process: 233 / 84

Step 5:
233 divided by 84 is 2 with a remainder of 65.
The next digit of our result is 2. 
Result so far: 982.0
Subtract 168 from 233 to get 65.
Include the next digit (5) from the dividend after 65, then repeat: 655 / 84

On to step 6:
655 divided by 84 is 7 with a remainder of 67.
The next digit of our result is 7. 
Result so far: 9827.0
If we take 588 away from 655, we end up with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Going ahead to step 7:
The number 84 fits into 670 7 times, leaving a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 9827.7
If we subtract 588 from 670, we 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 84 is 9 with a remainder of 64.
Write down 9 as next digit of the result. 
Result so far: 9827.79
If we take 756 away from 820, we end up 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.

Going ahead to step 9:
The number 84 fits into 640 7 times, leaving a remainder of 52.
The next digit of our result is 7. 
Result so far: 9827.797
The remainder is 52 after subtracting 588 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 10:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 9827.7976
The remainder is 16 after subtracting 504 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 11:
160 divided by 84 is 1 with a remainder of 76.
Record the quotient 1 as the next digit in the result. 
Result so far: 9827.79761
Subtracting 84 from 160 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.

Advancing to step 12:
760 divided by 84 is 9 with a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9827.797619
If we subtract 756 from 760, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 13:
If we divide 40 by 84, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9827.797619
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
If we divide 400 by 84, we get 4 and a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 9827.79761904
If we subtract 336 from 400, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final outcome is 9827.79761904, with a leftover of 6.4e-08.
