We're dividing 816285 by 84 
The aim is to understand the frequency of 84 in 816285.

Step 1:
84 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 84

Moving on to step 2:
84 goes into 81 0 times with a remainder of 81.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 84

Let's proceed to step 3:
816 divided by 84 is 9 with a remainder of 60.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 756 from 816, we get 60.
Append the next digit (2) from the dividend to 60 and continue with: 602 / 84

Moving on to step 4:
If we divide 602 by 84, we get 7 and a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 97.0
If we take 588 away from 602, we end up with 14.
Include the next digit (8) from the dividend after 14, then repeat: 148 / 84

Going ahead to step 5:
148 divided by 84 is 1 with a remainder of 64.
Use 1 as the next digit of our solution. 
Result so far: 971.0
Deduct 84 from 148 and we're left with 64.
Grab the next digit (5) from the dividend, add it to 64, then carry on: 645 / 84

Going ahead to step 6:
84 goes into 645 7 times with a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 9717.0
If we take 588 away from 645, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 7:
84 goes into 570 6 times with a remainder of 66.
The number 6 becomes the next digit in our result. 
Result so far: 9717.6
Deduct 504 from 570 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
If we divide 660 by 84, we get 7 and a remainder of 72.
The next digit of our result is 7. 
Result so far: 9717.67
If we take 588 away from 660, 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.

Going ahead to step 9:
If we divide 720 by 84, we get 8 and a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 9717.678
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 10:
84 can be fit into 480 5 times, resulting in a remainder of 60.
Record the quotient 5 as the next digit in the result. 
Result so far: 9717.6785
If we take 420 away from 480, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Let's proceed to step 11:
When dividing 600 by 84, we get 7 with a remainder of 12.
The number 7 becomes the next digit in our result. 
Result so far: 9717.67857
Subtract 588 from 600 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 12:
120 divided by 84 is 1 with a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 9717.678571
If we take 84 away from 120, we end up with 36.
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 13:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 9717.6785714
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 9717.67857142
The remainder is 72 after subtracting 168 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final outcome is 9717.67857142, with a leftover of 7.2e-08.
