We look at the division of 524257 by 84 
The aim is to understand the frequency of 84 in 524257.

On to step 1:
When dividing 5 by 84, we get 0 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.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 84

Moving on to step 2:
When dividing 52 by 84, we get 0 with a remainder of 52.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Fetch the next digit (4) from the dividend, attach it to 52 and continue: 524 / 84

Step 3:
If we divide 524 by 84, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 504 from 524 to get 20.
Bring next digit (2) of the dividend behind the 20 and repeat the process: 202 / 84

Let's proceed to step 4:
202 divided by 84 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
Subtracting 168 from 202 leaves us with 34.
Fetch the next digit (5) from the dividend, attach it to 34 and continue: 345 / 84

Going ahead to step 5:
84 can be fit into 345 4 times, resulting in a remainder of 9.
Put 4 as the next digit of the answer. 
Result so far: 624.0
Subtract 336 from 345 to get 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 84

Advancing to step 6:
97 divided by 84 is 1 with a remainder of 13.
Put 1 as the next digit of the answer. 
Result so far: 6241.0
If we subtract 84 from 97, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 7:
The number 84 fits into 130 1 times, leaving a remainder of 46.
Record the quotient 1 as the next digit in the result. 
Result so far: 6241.1
If we take 84 away from 130, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
When dividing 460 by 84, we get 5 with a remainder of 40.
Write down 5 as next digit of the result. 
Result so far: 6241.15
If we take 420 away from 460, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 84, we get 4 with a remainder of 64.
Use 4 as the next digit of our solution. 
Result so far: 6241.154
If we take 336 away from 400, we end up with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
The number 84 fits into 640 7 times, leaving a remainder of 52.
Put 7 as the next digit of the answer. 
Result so far: 6241.1547
If we take 588 away from 640, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
If we divide 520 by 84, we get 6 and a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 6241.15476
Subtract 504 from 520 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 12:
The number 84 fits into 160 1 times, leaving a remainder of 76.
Use 1 as the next digit of our solution. 
Result so far: 6241.154761
The remainder is 76 after subtracting 84 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 13:
84 can be fit into 760 9 times, resulting in a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 6241.1547619
Deduct 756 from 760 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 14:
If we divide 40 by 84, we get 0 and a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6241.1547619
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 6241.1547619 with a balance of 4e-08.
