We're dividing 586658 by 84 
The aim is to understand the frequency of 84 in 586658.

Going ahead to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 84

Step 2:
If we divide 58 by 84, we get 0 and a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 58 to get 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 84

On to step 3:
If we divide 586 by 84, we get 6 and a remainder of 82.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 504 away from 586, we end up with 82.
Include the next digit (6) from the dividend after 82, then repeat: 826 / 84

Moving on to step 4:
If we divide 826 by 84, we get 9 and a remainder of 70.
Record the quotient 9 as the next digit in the result. 
Result so far: 69.0
Deduct 756 from 826 and we're left with 70.
Append the next digit (5) from the dividend to 70 and continue with: 705 / 84

Moving on to step 5:
The number 84 fits into 705 8 times, leaving a remainder of 33.
Put 8 as the next digit of the answer. 
Result so far: 698.0
The remainder is 33 after subtracting 672 from 705.
Include the next digit (8) from the dividend after 33, then repeat: 338 / 84

On to step 6:
338 divided by 84 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 6984.0
If we subtract 336 from 338, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
The number 84 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 6984.0
Deduct 0 from 20 and we're left 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.

On to step 8:
200 divided by 84 is 2 with a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 6984.02
Subtract 168 from 200 to 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.

On to step 9:
320 divided by 84 is 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 6984.023
Deduct 252 from 320 and we're left 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.

Let's proceed to step 10:
If we divide 680 by 84, we get 8 and a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 6984.0238
Subtract 672 from 680 to 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.

Let's proceed to step 11:
84 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6984.0238
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.

Advancing to step 12:
The number 84 fits into 800 9 times, leaving a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 6984.023809
Subtracting 756 from 800 leaves us 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.

Moving on to step 13:
If we divide 440 by 84, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 6984.0238095
Subtract 420 from 440 to 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.

Going ahead to step 14:
When dividing 200 by 84, we get 2 with a remainder of 32.
Put 2 as the next digit of the answer. 
Result so far: 6984.02380952
The remainder is 32 after subtracting 168 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 6984.02380952 with a balance of 3.2e-08.
