We look at the division of 216073 by 84 
The aim is to understand the frequency of 84 in 216073.

Step 1:
If we divide 2 by 84, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 84

Going ahead to step 2:
21 divided by 84 is 0 with a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 21 and we're left with 21.
Fetch the next digit (6) from the dividend, attach it to 21 and continue: 216 / 84

Advancing to step 3:
84 can be fit into 216 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtract 168 from 216 to get 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 84

Step 4:
480 divided by 84 is 5 with a remainder of 60.
Write down 5 as next digit of the result. 
Result so far: 25.0
Deduct 420 from 480 and we're left with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 84

Step 5:
When dividing 607 by 84, we get 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 257.0
If we subtract 588 from 607, we get 19.
Include the next digit (3) from the dividend after 19, then repeat: 193 / 84

Step 6:
When dividing 193 by 84, we get 2 with a remainder of 25.
Use 2 as the next digit of our solution. 
Result so far: 2572.0
Subtract 168 from 193 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 7:
The number 84 fits into 250 2 times, leaving a remainder of 82.
Write down 2 as next digit of the result. 
Result so far: 2572.2
The remainder is 82 after subtracting 168 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 8:
84 goes into 820 9 times with a remainder of 64.
The number 9 becomes the next digit in our result. 
Result so far: 2572.29
Subtracting 756 from 820 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.

Let's proceed to step 9:
84 can be fit into 640 7 times, resulting in a remainder of 52.
Record the quotient 7 as the next digit in the result. 
Result so far: 2572.297
If we subtract 588 from 640, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 10:
The number 84 fits into 520 6 times, leaving a remainder of 16.
Put 6 as the next digit of the answer. 
Result so far: 2572.2976
Deduct 504 from 520 and we're left 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.

Going ahead to step 11:
160 divided by 84 is 1 with a remainder of 76.
The number 1 becomes the next digit in our result. 
Result so far: 2572.29761
If we subtract 84 from 160, 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.

Advancing to step 12:
When dividing 760 by 84, we get 9 with a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 2572.297619
If we take 756 away from 760, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 13:
84 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 2572.297619
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.

Let's proceed to step 14:
84 goes into 400 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 2572.29761904
Deduct 336 from 400 and we're left 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.

In conclusion, the division gives 2572.29761904 with a balance of 6.4e-08.
