580025 divided by 71 
The aim is to understand the frequency of 71 in 580025.

Advancing to step 1:
5 divided by 71 is 0 with a remainder of 5.
Write down 0 as next digit of the 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

Let's proceed to step 2:
58 divided by 71 is 0 with a remainder of 58.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 58, we end up with 58.
Include the next digit (0) from the dividend after 58, then repeat: 580 / 71

Advancing to step 3:
580 divided by 71 is 8 with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 568 from 580 to get 12.
Fetch the next digit (0) from the dividend, attach it to 12 and continue: 120 / 71

Going ahead to step 4:
71 goes into 120 1 times with a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 71 away from 120, we end up with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 71

Moving on to step 5:
The number 71 fits into 492 6 times, leaving a remainder of 66.
Record the quotient 6 as the next digit in the result. 
Result so far: 816.0
The remainder is 66 after subtracting 426 from 492.
Take the next digit (5) from the dividend and append it to 66, then repeat: 665 / 71

On to step 6:
If we divide 665 by 71, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 8169.0
Subtracting 639 from 665 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 7:
260 divided by 71 is 3 with a remainder of 47.
The next digit of our result is 3. 
Result so far: 8169.3
Subtracting 213 from 260 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Advancing to step 8:
71 goes into 470 6 times with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 8169.36
If we subtract 426 from 470, we get 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 9:
71 can be fit into 440 6 times, resulting in a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 8169.366
The remainder is 14 after subtracting 426 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 8169.366 with a remainder of 0.0014.
