868588 ÷ 84 
The aim is to understand the frequency of 84 in 868588.

Advancing to step 1:
84 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 84

On to step 2:
When dividing 86 by 84, we get 1 with a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 84 from 86 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 84

Going ahead to step 3:
84 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 28 to get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 84

On to step 4:
When dividing 285 by 84, we get 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
The remainder is 33 after subtracting 252 from 285.
Bring next digit (8) of the dividend behind the 33 and repeat the process: 338 / 84

Advancing to step 5:
If we divide 338 by 84, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1034.0
Deduct 336 from 338 and we're left with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 84

Going ahead to step 6:
When dividing 28 by 84, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 10340.0
Subtracting 0 from 28 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 7:
When dividing 280 by 84, we get 3 with a remainder of 28.
Put 3 as the next digit of the answer. 
Result so far: 10340.3
Deduct 252 from 280 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
84 goes into 280 3 times with a remainder of 28.
The next digit of our result is 3. 
Result so far: 10340.33
The remainder is 28 after subtracting 252 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

In conclusion, the division gives 10340.33 with a balance of 0.028.
