We look at the division of 330909 by 84 
The aim is to understand the frequency of 84 in 330909.

Step 1:
84 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 84

Let's proceed to step 2:
84 goes into 33 0 times with a remainder of 33.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 33 leaves us with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 84

Step 3:
330 divided by 84 is 3 with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 252 away from 330, we end up with 78.
Append the next digit (9) from the dividend to 78 and continue with: 789 / 84

On to step 4:
The number 84 fits into 789 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 756 from 789, we get 33.
Fetch the next digit (0) from the dividend, attach it to 33 and continue: 330 / 84

Advancing to step 5:
84 can be fit into 330 3 times, resulting in a remainder of 78.
Write down 3 as next digit of the result. 
Result so far: 393.0
The remainder is 78 after subtracting 252 from 330.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 84

Let's proceed to step 6:
The number 84 fits into 789 9 times, leaving a remainder of 33.
Record the quotient 9 as the next digit in the result. 
Result so far: 3939.0
Deduct 756 from 789 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 7:
84 goes into 330 3 times with a remainder of 78.
Use 3 as the next digit of our solution. 
Result so far: 3939.3
Deduct 252 from 330 and we're left with 78.
Since there are no more digits in the dividend, we add a zero to the remainder making it 780, and continue the process.

Let's proceed to step 8:
84 goes into 780 9 times with a remainder of 24.
Record the quotient 9 as the next digit in the result. 
Result so far: 3939.39
The remainder is 24 after subtracting 756 from 780.
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 9:
84 can be fit into 240 2 times, resulting in a remainder of 72.
Use 2 as the next digit of our solution. 
Result so far: 3939.392
If we take 168 away from 240, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 10:
The number 84 fits into 720 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 3939.3928
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 11:
84 goes into 480 5 times with a remainder of 60.
The number 5 becomes the next digit in our result. 
Result so far: 3939.39285
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.

Step 12:
600 divided by 84 is 7 with a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 3939.392857
Deduct 588 from 600 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 84 fits into 120 1 times, leaving a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 3939.3928571
If we take 84 away from 120, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
84 can be fit into 360 4 times, resulting in a remainder of 24.
Record the quotient 4 as the next digit in the result. 
Result so far: 3939.39285714
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 3939.39285714 with a balance of 2.4e-08.
