Let's divide 578209 by 71
The aim is to understand the frequency of 71 in 578209.

Step 1:
71 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 71

Moving on to step 2:
71 can be fit into 57 0 times, resulting in a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Take the next digit (8) from the dividend and append it to 57, then repeat: 578 / 71

Advancing to step 3:
578 divided by 71 is 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we take 568 away from 578, we end up with 10.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 71

Step 4:
102 divided by 71 is 1 with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtracting 71 from 102 leaves us with 31.
Include the next digit (0) from the dividend after 31, then repeat: 310 / 71

On to step 5:
If we divide 310 by 71, we get 4 and a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 814.0
If we subtract 284 from 310, we get 26.
Grab the next digit (9) from the dividend, add it to 26, then carry on: 269 / 71

Step 6:
When dividing 269 by 71, we get 3 with a remainder of 56.
Put 3 as the next digit of the answer. 
Result so far: 8143.0
Subtracting 213 from 269 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
71 goes into 560 7 times with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 8143.7
Deduct 497 from 560 and we're left with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

Step 8:
When dividing 630 by 71, we get 8 with a remainder of 62.
The next digit of our result is 8. 
Result so far: 8143.78
Subtract 568 from 630 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 9:
620 divided by 71 is 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8143.788
Subtracting 568 from 620 leaves us 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.

Our division results in 8143.788 with a remaining 0.0052.
