258770 ÷ 71 
The aim is to understand the frequency of 71 in 258770.

Let's proceed to step 1:
The number 71 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 71

Going ahead to step 2:
If we divide 25 by 71, we get 0 and a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Bring next digit (8) of the dividend behind the 25 and repeat the process: 258 / 71

On to step 3:
The number 71 fits into 258 3 times, leaving a remainder of 45.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 45 after subtracting 213 from 258.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 71

Let's proceed to step 4:
71 can be fit into 457 6 times, resulting in a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 36.0
Subtract 426 from 457 to get 31.
Include the next digit (7) from the dividend after 31, then repeat: 317 / 71

On to step 5:
The number 71 fits into 317 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 364.0
Deduct 284 from 317 and we're left with 33.
Append the next digit (0) from the dividend to 33 and continue with: 330 / 71

Advancing to step 6:
330 divided by 71 is 4 with a remainder of 46.
Write down 4 as next digit of the result. 
Result so far: 3644.0
Deduct 284 from 330 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 7:
71 goes into 460 6 times with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 3644.6
Subtracting 426 from 460 leaves us 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.

On to step 8:
340 divided by 71 is 4 with a remainder of 56.
The next digit of our result is 4. 
Result so far: 3644.64
If we take 284 away from 340, we end up 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 9:
The number 71 fits into 560 7 times, leaving a remainder of 63.
Write down 7 as next digit of the result. 
Result so far: 3644.647
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 10:
630 divided by 71 is 8 with a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 3644.6478
The remainder is 62 after subtracting 568 from 630.
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 11:
If we divide 620 by 71, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 3644.64788
If we take 568 away from 620, we end up 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.

The final result is 3644.64788 with a remainder of 5.2e-05.
