We look at the division of 288946 by 71 
The aim is to understand the frequency of 71 in 288946.

Going ahead to step 1:
When dividing 2 by 71, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 71

Let's proceed to step 2:
71 goes into 28 0 times with a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (8) from the dividend to 28 and continue with: 288 / 71

On to step 3:
If we divide 288 by 71, we get 4 and a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 4 after subtracting 284 from 288.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 71

Let's proceed to step 4:
When dividing 49 by 71, we get 0 with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Deduct 0 from 49 and we're left with 49.
Include the next digit (4) from the dividend after 49, then repeat: 494 / 71

On to step 5:
494 divided by 71 is 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 406.0
Deduct 426 from 494 and we're left with 68.
Include the next digit (6) from the dividend after 68, then repeat: 686 / 71

On to step 6:
71 goes into 686 9 times with a remainder of 47.
Use 9 as the next digit of our solution. 
Result so far: 4069.0
Subtract 639 from 686 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Moving on to step 7:
71 goes into 470 6 times with a remainder of 44.
Record the quotient 6 as the next digit in the result. 
Result so far: 4069.6
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.

On to step 8:
The number 71 fits into 440 6 times, leaving a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 4069.66
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.

After the division, we end up with 4069.66 and a remainder of 0.014.
