We look at the division of 198865 by 84 
The aim is to understand the frequency of 84 in 198865.

Step 1:
When dividing 1 by 84, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 84

On to step 2:
If we divide 19 by 84, we get 0 and a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 84

Moving on to step 3:
84 can be fit into 198 2 times, resulting in a remainder of 30.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we subtract 168 from 198, we get 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 84

On to step 4:
84 can be fit into 308 3 times, resulting in a remainder of 56.
Use 3 as the next digit of our solution. 
Result so far: 23.0
If we take 252 away from 308, we end up with 56.
Grab the next digit (6) from the dividend, add it to 56, then carry on: 566 / 84

Let's proceed to step 5:
84 goes into 566 6 times with a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 236.0
Deduct 504 from 566 and we're left with 62.
Grab the next digit (5) from the dividend, add it to 62, then carry on: 625 / 84

Moving on to step 6:
625 divided by 84 is 7 with a remainder of 37.
The next digit of our result is 7. 
Result so far: 2367.0
Subtract 588 from 625 to get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
The number 84 fits into 370 4 times, leaving a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 2367.4
The remainder is 34 after subtracting 336 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Let's proceed to step 8:
84 can be fit into 340 4 times, resulting in a remainder of 4.
The next digit of our result is 4. 
Result so far: 2367.44
If we subtract 336 from 340, 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.

In conclusion, the division gives 2367.44 with a balance of 0.004.
