We're dividing 763864 by 71 
The aim is to understand the frequency of 71 in 763864.

Going ahead to step 1:
71 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 71

Going ahead to step 2:
If we divide 76 by 71, we get 1 and a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 71 from 76 leaves us with 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 71

Moving on to step 3:
The number 71 fits into 53 0 times, leaving a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtracting 0 from 53 leaves us with 53.
Append the next digit (8) from the dividend to 53 and continue with: 538 / 71

Moving on to step 4:
71 can be fit into 538 7 times, resulting in a remainder of 41.
Write down 7 as next digit of the result. 
Result so far: 107.0
Subtract 497 from 538 to get 41.
Take the next digit (6) from the dividend and append it to 41, then repeat: 416 / 71

Going ahead to step 5:
71 can be fit into 416 5 times, resulting in a remainder of 61.
Write down 5 as next digit of the result. 
Result so far: 1075.0
If we subtract 355 from 416, we get 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 71

Step 6:
71 goes into 614 8 times with a remainder of 46.
Record the quotient 8 as the next digit in the result. 
Result so far: 10758.0
The remainder is 46 after subtracting 568 from 614.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 7:
71 can be fit into 460 6 times, resulting in a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 10758.6
Deduct 426 from 460 and we're left 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.

Going ahead to step 8:
71 can be fit into 340 4 times, resulting in a remainder of 56.
The number 4 becomes the next digit in our result. 
Result so far: 10758.64
Subtracting 284 from 340 leaves us 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.

Moving on to step 9:
When dividing 560 by 71, we get 7 with a remainder of 63.
The next digit of our result is 7. 
Result so far: 10758.647
If we take 497 away from 560, we end up 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.

Let's proceed to step 10:
The number 71 fits into 630 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 10758.6478
Deduct 568 from 630 and we're left with 62.
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:
71 goes into 620 8 times with a remainder of 52.
The next digit of our result is 8. 
Result so far: 10758.64788
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.

Our division results in 10758.64788 with a remaining 5.2e-05.
