We look at the division of 935989 by 71 
The aim is to understand the frequency of 71 in 935989.

Let's proceed to step 1:
The number 71 fits into 9 0 times, leaving a remainder of 9.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 71

Step 2:
93 divided by 71 is 1 with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 71 from 93 leaves us with 22.
Bring next digit (5) of the dividend behind the 22 and repeat the process: 225 / 71

Advancing to step 3:
The number 71 fits into 225 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 13.0
Subtract 213 from 225 to get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 71

Let's proceed to step 4:
The number 71 fits into 129 1 times, leaving a remainder of 58.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 58 after subtracting 71 from 129.
Take the next digit (8) from the dividend and append it to 58, then repeat: 588 / 71

On to step 5:
If we divide 588 by 71, we get 8 and a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1318.0
If we take 568 away from 588, we end up with 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 71

Advancing to step 6:
71 can be fit into 209 2 times, resulting in a remainder of 67.
Write down 2 as next digit of the result. 
Result so far: 13182.0
Subtract 142 from 209 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 7:
If we divide 670 by 71, we get 9 and a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 13182.9
Subtract 639 from 670 to get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 8:
71 goes into 310 4 times with a remainder of 26.
The next digit of our result is 4. 
Result so far: 13182.94
The remainder is 26 after subtracting 284 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 9:
If we divide 260 by 71, we get 3 and a remainder of 47.
Write down 3 as next digit of the result. 
Result so far: 13182.943
The remainder is 47 after subtracting 213 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 10:
When dividing 470 by 71, we get 6 with a remainder of 44.
The next digit of our result is 6. 
Result so far: 13182.9436
If we take 426 away from 470, we end up with 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 11:
If we divide 440 by 71, we get 6 and a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 13182.94366
Deduct 426 from 440 and we're left with 14.
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 outcome is 13182.94366, with a leftover of 1.4e-05.
