We look at the division of 575285 by 84 
The aim is to understand the frequency of 84 in 575285.

Let's proceed to step 1:
The number 84 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 84

On to step 2:
57 divided by 84 is 0 with a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Take the next digit (5) from the dividend and append it to 57, then repeat: 575 / 84

Moving on to step 3:
575 divided by 84 is 6 with a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 504 away from 575, we end up with 71.
Include the next digit (2) from the dividend after 71, then repeat: 712 / 84

On to step 4:
If we divide 712 by 84, we get 8 and a remainder of 40.
The next digit of our result is 8. 
Result so far: 68.0
Deduct 672 from 712 and we're left with 40.
Grab the next digit (8) from the dividend, add it to 40, then carry on: 408 / 84

Step 5:
If we divide 408 by 84, we get 4 and a remainder of 72.
Use 4 as the next digit of our solution. 
Result so far: 684.0
Subtracting 336 from 408 leaves us with 72.
Bring next digit (5) of the dividend behind the 72 and repeat the process: 725 / 84

Moving on to step 6:
84 goes into 725 8 times with a remainder of 53.
The number 8 becomes the next digit in our result. 
Result so far: 6848.0
Deduct 672 from 725 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
84 can be fit into 530 6 times, resulting in a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 6848.6
Subtracting 504 from 530 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
When dividing 260 by 84, we get 3 with a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 6848.63
If we subtract 252 from 260, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
When dividing 80 by 84, we get 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6848.63
If we subtract 0 from 80, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 10:
When dividing 800 by 84, we get 9 with a remainder of 44.
The next digit of our result is 9. 
Result so far: 6848.6309
Deduct 756 from 800 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 11:
If we divide 440 by 84, we get 5 and a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 6848.63095
If we take 420 away from 440, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
84 goes into 200 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 6848.630952
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 13:
If we divide 320 by 84, we get 3 and a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 6848.6309523
If we take 252 away from 320, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 14:
If we divide 680 by 84, we get 8 and a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 6848.63095238
If we take 672 away from 680, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 6848.63095238 with a balance of 8e-09.
