We're dividing 77051 by 71 
The aim is to understand the frequency of 71 in 77051.

Step 1:
7 divided by 71 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 71

Step 2:
77 divided by 71 is 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 6 after subtracting 71 from 77.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 71

Going ahead to step 3:
When dividing 60 by 71, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 60 and we're left with 60.
Bring next digit (5) of the dividend behind the 60 and repeat the process: 605 / 71

On to step 4:
If we divide 605 by 71, we get 8 and a remainder of 37.
Put 8 as the next digit of the answer. 
Result so far: 108.0
Subtracting 568 from 605 leaves us with 37.
Take the next digit (1) from the dividend and append it to 37, then repeat: 371 / 71

Advancing to step 5:
When dividing 371 by 71, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 1085.0
Subtract 355 from 371 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 6:
The number 71 fits into 160 2 times, leaving a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 1085.2
If we take 142 away from 160, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
The number 71 fits into 180 2 times, leaving a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 1085.22
Subtract 142 from 180 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

After the division, we end up with 1085.22 and a remainder of 0.038.
