We look at the division of 203311 by 71 
The aim is to understand the frequency of 71 in 203311.

Going ahead to step 1:
If we divide 2 by 71, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 71

Moving on to step 2:
The number 71 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Include the next digit (3) from the dividend after 20, then repeat: 203 / 71

Step 3:
If we divide 203 by 71, we get 2 and a remainder of 61.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 142 away from 203, we end up with 61.
Fetch the next digit (3) from the dividend, attach it to 61 and continue: 613 / 71

Moving on to step 4:
613 divided by 71 is 8 with a remainder of 45.
Write down 8 as next digit of the result. 
Result so far: 28.0
The remainder is 45 after subtracting 568 from 613.
Include the next digit (1) from the dividend after 45, then repeat: 451 / 71

Let's proceed to step 5:
71 goes into 451 6 times with a remainder of 25.
Record the quotient 6 as the next digit in the result. 
Result so far: 286.0
If we take 426 away from 451, we end up with 25.
Fetch the next digit (1) from the dividend, attach it to 25 and continue: 251 / 71

Step 6:
The number 71 fits into 251 3 times, leaving a remainder of 38.
The number 3 becomes the next digit in our result. 
Result so far: 2863.0
Subtract 213 from 251 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.

Going ahead to step 7:
If we divide 380 by 71, we get 5 and a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 2863.5
Subtracting 355 from 380 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 8:
71 goes into 250 3 times with a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 2863.53
Deduct 213 from 250 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 9:
71 can be fit into 370 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 2863.535
If we take 355 away from 370, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
When dividing 150 by 71, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 2863.5352
Deduct 142 from 150 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 11:
If we divide 80 by 71, we get 1 and a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 2863.53521
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 12:
90 divided by 71 is 1 with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 2863.535211
If we subtract 71 from 90, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 2863.535211 with a remaining 1.9e-06.
