We divide 512828 by 84
The aim is to understand the frequency of 84 in 512828.

Going ahead to step 1:
When dividing 5 by 84, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 84

Going ahead to step 2:
When dividing 51 by 84, we get 0 with a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 51, we get 51.
Bring next digit (2) of the dividend behind the 51 and repeat the process: 512 / 84

Let's proceed to step 3:
The number 84 fits into 512 6 times, leaving a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 504 from 512, we get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 84

Moving on to step 4:
When dividing 88 by 84, we get 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 61.0
If we subtract 84 from 88, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 84

Step 5:
42 divided by 84 is 0 with a remainder of 42.
Record the quotient 0 as the next digit in the result. 
Result so far: 610.0
Subtract 0 from 42 to get 42.
Fetch the next digit (8) from the dividend, attach it to 42 and continue: 428 / 84

Moving on to step 6:
The number 84 fits into 428 5 times, leaving a remainder of 8.
The next digit of our result is 5. 
Result so far: 6105.0
Subtracting 420 from 428 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.

Going ahead to step 7:
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: 6105.0
Deduct 0 from 80 and we're left with 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 8:
84 can be fit into 800 9 times, resulting in a remainder of 44.
Write down 9 as next digit of the result. 
Result so far: 6105.09
Deduct 756 from 800 and we're left 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.

On to step 9:
When dividing 440 by 84, we get 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 6105.095
Subtracting 420 from 440 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 10:
If we divide 200 by 84, we get 2 and a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 6105.0952
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 11:
When dividing 320 by 84, we get 3 with a remainder of 68.
The next digit of our result is 3. 
Result so far: 6105.09523
Subtract 252 from 320 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 12:
84 goes into 680 8 times with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 6105.095238
If we subtract 672 from 680, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 84 is 0 with a remainder of 80.
Use 0 as the next digit of our solution. 
Result so far: 6105.095238
Subtracting 0 from 80 leaves us with 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.
Put 9 as the next digit of the answer. 
Result so far: 6105.09523809
The remainder is 44 after subtracting 756 from 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Our division results in 6105.09523809 with a remaining 4.4e-08.
