522516 divided by 84 
The aim is to understand the frequency of 84 in 522516.

On to step 1:
84 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 84

Going ahead to step 2:
84 can be fit into 52 0 times, resulting in a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Append the next digit (2) from the dividend to 52 and continue with: 522 / 84

On to step 3:
84 goes into 522 6 times with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Subtract 504 from 522 to get 18.
Fetch the next digit (5) from the dividend, attach it to 18 and continue: 185 / 84

On to step 4:
84 goes into 185 2 times with a remainder of 17.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
If we subtract 168 from 185, we get 17.
Take the next digit (1) from the dividend and append it to 17, then repeat: 171 / 84

Going ahead to step 5:
84 can be fit into 171 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 622.0
Subtracting 168 from 171 leaves us with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 84

Let's proceed to step 6:
If we divide 36 by 84, we get 0 and a remainder of 36.
The next digit of our result is 0. 
Result so far: 6220.0
If we take 0 away from 36, 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.

On to step 7:
84 goes into 360 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 6220.4
The remainder is 24 after subtracting 336 from 360.
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 8:
84 goes into 240 2 times with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 6220.42
Subtract 168 from 240 to 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 9:
84 goes into 720 8 times with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 6220.428
The remainder is 48 after subtracting 672 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
The number 84 fits into 480 5 times, leaving a remainder of 60.
Use 5 as the next digit of our solution. 
Result so far: 6220.4285
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 11:
600 divided by 84 is 7 with a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 6220.42857
Subtract 588 from 600 to 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.

Step 12:
84 goes into 120 1 times with a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 6220.428571
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 13:
84 can be fit into 360 4 times, resulting in a remainder of 24.
The next digit of our result is 4. 
Result so far: 6220.4285714
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.

Moving on to step 14:
When dividing 240 by 84, we get 2 with a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 6220.42857142
Subtracting 168 from 240 leaves us 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.

The final result is 6220.42857142 with a remainder of 7.2e-08.
