We look at the division of 584842 by 71 
The aim is to understand the frequency of 71 in 584842.

Going ahead to step 1:
When dividing 5 by 71, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 71

On to step 2:
71 goes into 58 0 times with a remainder of 58.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 58 after subtracting 0 from 58.
Grab the next digit (4) from the dividend, add it to 58, then carry on: 584 / 71

Moving on to step 3:
When dividing 584 by 71, we get 8 with a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 16 after subtracting 568 from 584.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 71

Moving on to step 4:
If we divide 168 by 71, we get 2 and a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
If we subtract 142 from 168, we get 26.
Append the next digit (4) from the dividend to 26 and continue with: 264 / 71

Let's proceed to step 5:
71 can be fit into 264 3 times, resulting in a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 823.0
Subtract 213 from 264 to get 51.
Include the next digit (2) from the dividend after 51, then repeat: 512 / 71

Moving on to step 6:
512 divided by 71 is 7 with a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 8237.0
Subtract 497 from 512 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
71 can be fit into 150 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 8237.2
If we take 142 away from 150, we end up 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.

Step 8:
The number 71 fits into 80 1 times, leaving a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 8237.21
Subtract 71 from 80 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 9:
If we divide 90 by 71, we get 1 and a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 8237.211
The remainder is 19 after subtracting 71 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The quotient of the division is 8237.211, and the remainder is 0.0019.
