We're dividing 312730 by 84 
The aim is to understand the frequency of 84 in 312730.

Advancing to step 1:
84 goes into 3 0 times with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 84

Going ahead to step 2:
31 divided by 84 is 0 with a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 31 after subtracting 0 from 31.
Bring next digit (2) of the dividend behind the 31 and repeat the process: 312 / 84

Step 3:
When dividing 312 by 84, we get 3 with a remainder of 60.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 252 from 312 leaves us with 60.
Include the next digit (7) from the dividend after 60, then repeat: 607 / 84

Let's proceed to step 4:
607 divided by 84 is 7 with a remainder of 19.
The next digit of our result is 7. 
Result so far: 37.0
The remainder is 19 after subtracting 588 from 607.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 84

On to step 5:
When dividing 193 by 84, we get 2 with a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 372.0
If we subtract 168 from 193, we get 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 84

Step 6:
250 divided by 84 is 2 with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 3722.0
If we subtract 168 from 250, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 7:
84 can be fit into 820 9 times, resulting in a remainder of 64.
Put 9 as the next digit of the answer. 
Result so far: 3722.9
The remainder is 64 after subtracting 756 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 8:
640 divided by 84 is 7 with a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 3722.97
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 9:
If we divide 520 by 84, we get 6 and a remainder of 16.
Use 6 as the next digit of our solution. 
Result so far: 3722.976
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
The number 84 fits into 160 1 times, leaving a remainder of 76.
The next digit of our result is 1. 
Result so far: 3722.9761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 11:
84 goes into 760 9 times with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 3722.97619
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 12:
84 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 3722.97619
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
84 goes into 400 4 times with a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 3722.9761904
Subtract 336 from 400 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 14:
If we divide 640 by 84, we get 7 and a remainder of 52.
The next digit of our result is 7. 
Result so far: 3722.97619047
Subtract 588 from 640 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

In conclusion, the division gives 3722.97619047 with a balance of 5.2e-08.
