We look at the division of 586340 by 84 
The aim is to understand the frequency of 84 in 586340.

Let's proceed to step 1:
84 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 84

Moving on to step 2:
84 goes into 58 0 times with a remainder of 58.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 58 leaves us with 58.
Bring next digit (6) of the dividend behind the 58 and repeat the process: 586 / 84

Going ahead to step 3:
When dividing 586 by 84, we get 6 with a remainder of 82.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 504 from 586 and we're left with 82.
Take the next digit (3) from the dividend and append it to 82, then repeat: 823 / 84

Advancing to step 4:
The number 84 fits into 823 9 times, leaving a remainder of 67.
The next digit of our result is 9. 
Result so far: 69.0
If we subtract 756 from 823, we get 67.
Fetch the next digit (4) from the dividend, attach it to 67 and continue: 674 / 84

On to step 5:
674 divided by 84 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 698.0
Deduct 672 from 674 and we're left with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 84

Advancing to step 6:
When dividing 20 by 84, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 6980.0
If we subtract 0 from 20, we 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.

Let's proceed to step 7:
The number 84 fits into 200 2 times, leaving a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 6980.2
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 8:
When dividing 320 by 84, we get 3 with a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 6980.23
Subtracting 252 from 320 leaves us 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 9:
When dividing 680 by 84, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 6980.238
Deduct 672 from 680 and we're left 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.

Let's proceed to step 10:
84 can be fit into 80 0 times, resulting in a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 6980.238
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 11:
800 divided by 84 is 9 with a remainder of 44.
Use 9 as the next digit of our solution. 
Result so far: 6980.23809
If we take 756 away from 800, we end up 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.

Step 12:
84 can be fit into 440 5 times, resulting in a remainder of 20.
Write down 5 as next digit of the result. 
Result so far: 6980.238095
If we subtract 420 from 440, we 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.

Moving on to step 13:
If we divide 200 by 84, we get 2 and a remainder of 32.
Use 2 as the next digit of our solution. 
Result so far: 6980.2380952
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 14:
84 can be fit into 320 3 times, resulting in a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 6980.23809523
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.

After the division, we end up with 6980.23809523 and a remainder of 6.8e-08.
