587843 ÷ 71 
The aim is to understand the frequency of 71 in 587843.

Let's proceed to step 1:
71 goes into 5 0 times 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.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 71

Moving on to step 2:
When dividing 58 by 71, we get 0 with a remainder of 58.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 71

On to step 3:
71 goes into 587 8 times with a remainder of 19.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtract 568 from 587 to get 19.
Take the next digit (8) from the dividend and append it to 19, then repeat: 198 / 71

Going ahead to step 4:
The number 71 fits into 198 2 times, leaving a remainder of 56.
The next digit of our result is 2. 
Result so far: 82.0
If we subtract 142 from 198, we get 56.
Grab the next digit (4) from the dividend, add it to 56, then carry on: 564 / 71

Advancing to step 5:
564 divided by 71 is 7 with a remainder of 67.
The number 7 becomes the next digit in our result. 
Result so far: 827.0
The remainder is 67 after subtracting 497 from 564.
Append the next digit (3) from the dividend to 67 and continue with: 673 / 71

Advancing to step 6:
71 goes into 673 9 times with a remainder of 34.
The number 9 becomes the next digit in our result. 
Result so far: 8279.0
If we take 639 away from 673, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 7:
If we divide 340 by 71, we get 4 and a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 8279.4
Deduct 284 from 340 and we're left 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.

On to step 8:
If we divide 560 by 71, we get 7 and a remainder of 63.
The number 7 becomes the next digit in our result. 
Result so far: 8279.47
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.

Moving on to step 9:
If we divide 630 by 71, we get 8 and a remainder of 62.
Write down 8 as next digit of the result. 
Result so far: 8279.478
If we subtract 568 from 630, we 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.

Moving on to step 10:
When dividing 620 by 71, we get 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 8279.4788
The remainder is 52 after subtracting 568 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

After the division, we end up with 8279.4788 and a remainder of 0.00052.
