We're dividing 82980 by 84 
The aim is to understand the frequency of 84 in 82980.

On to step 1:
84 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Take the next digit (2) from the dividend and append it to 8, then repeat: 82 / 84

Let's proceed to step 2:
82 divided by 84 is 0 with a remainder of 82.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 82, we end up with 82.
Grab the next digit (9) from the dividend, add it to 82, then carry on: 829 / 84

Step 3:
The number 84 fits into 829 9 times, leaving a remainder of 73.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 756 from 829 leaves us with 73.
Bring next digit (8) of the dividend behind the 73 and repeat the process: 738 / 84

On to step 4:
When dividing 738 by 84, we get 8 with a remainder of 66.
Write down 8 as next digit of the result. 
Result so far: 98.0
Deduct 672 from 738 and we're left with 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 84

Step 5:
660 divided by 84 is 7 with a remainder of 72.
The number 7 becomes the next digit in our result. 
Result so far: 987.0
If we subtract 588 from 660, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 6:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 987.8
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 7:
When dividing 480 by 84, we get 5 with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 987.85
The remainder is 60 after subtracting 420 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 8:
84 goes into 600 7 times with a remainder of 12.
The next digit of our result is 7. 
Result so far: 987.857
If we subtract 588 from 600, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
120 divided by 84 is 1 with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 987.8571
Subtract 84 from 120 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
The number 84 fits into 360 4 times, leaving a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 987.85714
If we subtract 336 from 360, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 11:
When dividing 240 by 84, we get 2 with a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 987.857142
If we subtract 168 from 240, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 12:
720 divided by 84 is 8 with a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 987.8571428
Subtract 672 from 720 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 13:
If we divide 480 by 84, we get 5 and a remainder of 60.
The next digit of our result is 5. 
Result so far: 987.85714285
Subtract 420 from 480 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

The final result is 987.85714285 with a remainder of 6e-08.
