We divide 539127 by 84
The aim is to understand the frequency of 84 in 539127.

Going ahead to step 1:
5 divided by 84 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 84

Step 2:
If we divide 53 by 84, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (9) from the dividend to 53 and continue with: 539 / 84

Step 3:
84 can be fit into 539 6 times, resulting in a remainder of 35.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 35 after subtracting 504 from 539.
Grab the next digit (1) from the dividend, add it to 35, then carry on: 351 / 84

Let's proceed to step 4:
351 divided by 84 is 4 with a remainder of 15.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 15 after subtracting 336 from 351.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 84

Step 5:
The number 84 fits into 152 1 times, leaving a remainder of 68.
The number 1 becomes the next digit in our result. 
Result so far: 641.0
If we take 84 away from 152, we end up with 68.
Fetch the next digit (7) from the dividend, attach it to 68 and continue: 687 / 84

Advancing to step 6:
If we divide 687 by 84, we get 8 and a remainder of 15.
The number 8 becomes the next digit in our result. 
Result so far: 6418.0
Deduct 672 from 687 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
150 divided by 84 is 1 with a remainder of 66.
Use 1 as the next digit of our solution. 
Result so far: 6418.1
Subtract 84 from 150 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 8:
660 divided by 84 is 7 with a remainder of 72.
Write down 7 as next digit of the result. 
Result so far: 6418.17
If we subtract 588 from 660, we 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.

Moving on to step 9:
84 can be fit into 720 8 times, resulting in a remainder of 48.
The number 8 becomes the next digit in our result. 
Result so far: 6418.178
If we take 672 away from 720, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 10:
84 goes into 480 5 times with a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 6418.1785
If we subtract 420 from 480, we get 60.
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:
The number 84 fits into 600 7 times, leaving a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 6418.17857
The remainder is 12 after subtracting 588 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 12:
The number 84 fits into 120 1 times, leaving a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 6418.178571
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
84 goes into 360 4 times with a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 6418.1785714
Subtract 336 from 360 to 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.

On to step 14:
84 can be fit into 240 2 times, resulting in a remainder of 72.
The next digit of our result is 2. 
Result so far: 6418.17857142
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 outcome is 6418.17857142, with a leftover of 7.2e-08.
