We look at the division of 764661 by 71 
The aim is to understand the frequency of 71 in 764661.

Advancing to step 1:
The number 71 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 71

On to step 2:
The number 71 fits into 76 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 71 away from 76, we end up with 5.
Fetch the next digit (4) from the dividend, attach it to 5 and continue: 54 / 71

Moving on to step 3:
The number 71 fits into 54 0 times, leaving a remainder of 54.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 54 and we're left with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 71

Step 4:
The number 71 fits into 546 7 times, leaving a remainder of 49.
The number 7 becomes the next digit in our result. 
Result so far: 107.0
Deduct 497 from 546 and we're left with 49.
Take the next digit (6) from the dividend and append it to 49, then repeat: 496 / 71

On to step 5:
71 can be fit into 496 6 times, resulting in a remainder of 70.
The next digit of our result is 6. 
Result so far: 1076.0
If we take 426 away from 496, we end up with 70.
Grab the next digit (1) from the dividend, add it to 70, then carry on: 701 / 71

Going ahead to step 6:
When dividing 701 by 71, we get 9 with a remainder of 62.
Put 9 as the next digit of the answer. 
Result so far: 10769.0
The remainder is 62 after subtracting 639 from 701.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 7:
71 can be fit into 620 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 10769.8
The remainder is 52 after subtracting 568 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 8:
If we divide 520 by 71, we get 7 and a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 10769.87
Subtract 497 from 520 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 9:
When dividing 230 by 71, we get 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 10769.873
Deduct 213 from 230 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 10:
71 can be fit into 170 2 times, resulting in a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 10769.8732
Subtract 142 from 170 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 11:
280 divided by 71 is 3 with a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 10769.87323
Subtract 213 from 280 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.

Moving on to step 12:
The number 71 fits into 670 9 times, leaving a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 10769.873239
If we take 639 away from 670, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 13:
71 can be fit into 310 4 times, resulting in a remainder of 26.
Put 4 as the next digit of the answer. 
Result so far: 10769.8732394
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.

Going ahead to step 14:
260 divided by 71 is 3 with a remainder of 47.
The number 3 becomes the next digit in our result. 
Result so far: 10769.87323943
If we subtract 213 from 260, we 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.

In conclusion, the division gives 10769.87323943 with a balance of 4.7e-08.
