We look at the division of 2535 by 71 
The aim is to understand the frequency of 71 in 2535.

On to step 1:
2 divided by 71 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 71

Step 2:
71 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (3) of the dividend behind the 25 and repeat the process: 253 / 71

Advancing to step 3:
71 goes into 253 3 times with a remainder of 40.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 213 from 253 leaves us with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 71

Going ahead to step 4:
405 divided by 71 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 35.0
Subtract 355 from 405 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 5:
The number 71 fits into 500 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 35.7
If we subtract 497 from 500, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
71 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 35.7
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 7:
300 divided by 71 is 4 with a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 35.704
Subtract 284 from 300 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 8:
160 divided by 71 is 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 35.7042
If we subtract 142 from 160, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
If we divide 180 by 71, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 35.70422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 35.70422, and the remainder is 3.8e-05.
