715931 ÷ 84 
The aim is to understand the frequency of 84 in 715931.

Advancing to step 1:
84 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 84

Going ahead to step 2:
When dividing 71 by 84, we get 0 with a remainder of 71.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 71 to get 71.
Include the next digit (5) from the dividend after 71, then repeat: 715 / 84

Going ahead to step 3:
The number 84 fits into 715 8 times, leaving a remainder of 43.
The next digit of our result is 8. 
Result so far: 8.0
The remainder is 43 after subtracting 672 from 715.
Bring next digit (9) of the dividend behind the 43 and repeat the process: 439 / 84

Moving on to step 4:
If we divide 439 by 84, we get 5 and a remainder of 19.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Deduct 420 from 439 and we're left with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 84

Advancing to step 5:
84 goes into 193 2 times with a remainder of 25.
The number 2 becomes the next digit in our result. 
Result so far: 852.0
Subtracting 168 from 193 leaves us with 25.
Grab the next digit (1) from the dividend, add it to 25, then carry on: 251 / 84

Moving on to step 6:
251 divided by 84 is 2 with a remainder of 83.
The number 2 becomes the next digit in our result. 
Result so far: 8522.0
The remainder is 83 after subtracting 168 from 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 7:
830 divided by 84 is 9 with a remainder of 74.
Use 9 as the next digit of our solution. 
Result so far: 8522.9
Subtract 756 from 830 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 8:
The number 84 fits into 740 8 times, leaving a remainder of 68.
Record the quotient 8 as the next digit in the result. 
Result so far: 8522.98
Subtracting 672 from 740 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Step 9:
84 can be fit into 680 8 times, resulting in a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 8522.988
Subtracting 672 from 680 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 8522.988 with a balance of 0.0008.
