We look at the division of 658822 by 84 
The aim is to understand the frequency of 84 in 658822.

Let's proceed to step 1:
The number 84 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 84

Going ahead to step 2:
If we divide 65 by 84, we get 0 and a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 65 after subtracting 0 from 65.
Grab the next digit (8) from the dividend, add it to 65, then carry on: 658 / 84

On to step 3:
84 goes into 658 7 times with a remainder of 70.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 588 from 658, we get 70.
Grab the next digit (8) from the dividend, add it to 70, then carry on: 708 / 84

Going ahead to step 4:
84 can be fit into 708 8 times, resulting in a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
The remainder is 36 after subtracting 672 from 708.
Grab the next digit (2) from the dividend, add it to 36, then carry on: 362 / 84

Going ahead to step 5:
362 divided by 84 is 4 with a remainder of 26.
The next digit of our result is 4. 
Result so far: 784.0
Deduct 336 from 362 and we're left with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 84

On to step 6:
The number 84 fits into 262 3 times, leaving a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 7843.0
If we take 252 away from 262, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 7:
When dividing 100 by 84, we get 1 with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 7843.1
Deduct 84 from 100 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.

Moving on to step 8:
84 goes into 160 1 times with a remainder of 76.
Write down 1 as next digit of the result. 
Result so far: 7843.11
If we take 84 away from 160, we end up with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 7843.11 with a remaining 0.076.
