We look at the division of 140084 by 84 
The aim is to understand the frequency of 84 in 140084.

On to step 1:
When dividing 1 by 84, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 84

Let's proceed to step 2:
When dividing 14 by 84, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 14 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 84

Moving on to step 3:
84 can be fit into 140 1 times, resulting in a remainder of 56.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 84 away from 140, we end up with 56.
Include the next digit (0) from the dividend after 56, then repeat: 560 / 84

Advancing to step 4:
84 goes into 560 6 times with a remainder of 56.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Deduct 504 from 560 and we're left with 56.
Grab the next digit (8) from the dividend, add it to 56, then carry on: 568 / 84

Advancing to step 5:
The number 84 fits into 568 6 times, leaving a remainder of 64.
The next digit of our result is 6. 
Result so far: 166.0
If we subtract 504 from 568, we get 64.
Grab the next digit (4) from the dividend, add it to 64, then carry on: 644 / 84

Step 6:
When dividing 644 by 84, we get 7 with a remainder of 56.
Write down 7 as next digit of the result. 
Result so far: 1667.0
The remainder is 56 after subtracting 588 from 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 7:
84 goes into 560 6 times with a remainder of 56.
Record the quotient 6 as the next digit in the result. 
Result so far: 1667.6
Deduct 504 from 560 and we're left with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Let's proceed to step 8:
560 divided by 84 is 6 with a remainder of 56.
The next digit of our result is 6. 
Result so far: 1667.66
The remainder is 56 after subtracting 504 from 560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 1667.66 with a balance of 0.056.
