We look at the division of 799752 by 71 
The aim is to understand the frequency of 71 in 799752.

On to step 1:
71 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Take the next digit (9) from the dividend and append it to 7, then repeat: 79 / 71

Step 2:
When dividing 79 by 71, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 71 from 79 to get 8.
Bring next digit (9) of the dividend behind the 8 and repeat the process: 89 / 71

Advancing to step 3:
The number 71 fits into 89 1 times, leaving a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we subtract 71 from 89, we get 18.
Include the next digit (7) from the dividend after 18, then repeat: 187 / 71

Advancing to step 4:
The number 71 fits into 187 2 times, leaving a remainder of 45.
The next digit of our result is 2. 
Result so far: 112.0
Deduct 142 from 187 and we're left with 45.
Grab the next digit (5) from the dividend, add it to 45, then carry on: 455 / 71

Step 5:
When dividing 455 by 71, we get 6 with a remainder of 29.
Write down 6 as next digit of the result. 
Result so far: 1126.0
If we subtract 426 from 455, we get 29.
Append the next digit (2) from the dividend to 29 and continue with: 292 / 71

Moving on to step 6:
71 goes into 292 4 times with a remainder of 8.
Write down 4 as next digit of the result. 
Result so far: 11264.0
If we subtract 284 from 292, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 7:
71 goes into 80 1 times with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 11264.1
Deduct 71 from 80 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 8:
When dividing 90 by 71, we get 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 11264.11
Deduct 71 from 90 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

The final outcome is 11264.11, with a leftover of 0.019.
