We're dividing 872705 by 84 
The aim is to understand the frequency of 84 in 872705.

Step 1:
The number 84 fits into 8 0 times, leaving a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 84

Let's proceed to step 2:
87 divided by 84 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 84 from 87 to get 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 84

On to step 3:
84 goes into 32 0 times with a remainder of 32.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 32 after subtracting 0 from 32.
Grab the next digit (7) from the dividend, add it to 32, then carry on: 327 / 84

Going ahead to step 4:
327 divided by 84 is 3 with a remainder of 75.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Deduct 252 from 327 and we're left with 75.
Take the next digit (0) from the dividend and append it to 75, then repeat: 750 / 84

Going ahead to step 5:
84 can be fit into 750 8 times, resulting in a remainder of 78.
Put 8 as the next digit of the answer. 
Result so far: 1038.0
Deduct 672 from 750 and we're left with 78.
Fetch the next digit (5) from the dividend, attach it to 78 and continue: 785 / 84

Moving on to step 6:
84 goes into 785 9 times with a remainder of 29.
Put 9 as the next digit of the answer. 
Result so far: 10389.0
The remainder is 29 after subtracting 756 from 785.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
The number 84 fits into 290 3 times, leaving a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 10389.3
If we subtract 252 from 290, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 8:
84 can be fit into 380 4 times, resulting in a remainder of 44.
Use 4 as the next digit of our solution. 
Result so far: 10389.34
If we take 336 away from 380, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
When dividing 440 by 84, we get 5 with a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 10389.345
If we subtract 420 from 440, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 10:
If we divide 200 by 84, we get 2 and a remainder of 32.
The next digit of our result is 2. 
Result so far: 10389.3452
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 11:
If we divide 320 by 84, we get 3 and a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 10389.34523
If we take 252 away from 320, we end up 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 12:
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: 10389.345238
The remainder is 8 after subtracting 672 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
If we divide 80 by 84, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 10389.345238
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 14:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 10389.34523809
If we subtract 756 from 800, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

In conclusion, the division gives 10389.34523809 with a balance of 4.4e-08.
