We're dividing 779856 by 71 
The aim is to understand the frequency of 71 in 779856.

Advancing to step 1:
When dividing 7 by 71, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 71

Going ahead to step 2:
71 goes into 77 1 times with a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 71 from 77 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 71

Step 3:
When dividing 69 by 71, we get 0 with a remainder of 69.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we subtract 0 from 69, we get 69.
Fetch the next digit (8) from the dividend, attach it to 69 and continue: 698 / 71

Going ahead to step 4:
71 goes into 698 9 times with a remainder of 59.
Put 9 as the next digit of the answer. 
Result so far: 109.0
The remainder is 59 after subtracting 639 from 698.
Include the next digit (5) from the dividend after 59, then repeat: 595 / 71

On to step 5:
If we divide 595 by 71, we get 8 and a remainder of 27.
Write down 8 as next digit of the result. 
Result so far: 1098.0
Deduct 568 from 595 and we're left with 27.
Fetch the next digit (6) from the dividend, attach it to 27 and continue: 276 / 71

Step 6:
71 goes into 276 3 times with a remainder of 63.
Record the quotient 3 as the next digit in the result. 
Result so far: 10983.0
If we take 213 away from 276, 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.

On to step 7:
The number 71 fits into 630 8 times, leaving a remainder of 62.
The next digit of our result is 8. 
Result so far: 10983.8
The remainder is 62 after subtracting 568 from 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 8:
620 divided by 71 is 8 with a remainder of 52.
Record the quotient 8 as the next digit in the result. 
Result so far: 10983.88
Deduct 568 from 620 and we're left 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.

The final result is 10983.88 with a remainder of 0.052.
