We look at the division of 255769 by 71 
The aim is to understand the frequency of 71 in 255769.

Let's proceed to step 1:
If we divide 2 by 71, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 71

Let's proceed to step 2:
25 divided by 71 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Fetch the next digit (5) from the dividend, attach it to 25 and continue: 255 / 71

On to step 3:
When dividing 255 by 71, we get 3 with a remainder of 42.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 42 after subtracting 213 from 255.
Bring next digit (7) of the dividend behind the 42 and repeat the process: 427 / 71

Advancing to step 4:
71 goes into 427 6 times with a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 1 after subtracting 426 from 427.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 71

Moving on to step 5:
When dividing 16 by 71, we get 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 360.0
If we take 0 away from 16, we end up with 16.
Fetch the next digit (9) from the dividend, attach it to 16 and continue: 169 / 71

Moving on to step 6:
The number 71 fits into 169 2 times, leaving a remainder of 27.
Write down 2 as next digit of the result. 
Result so far: 3602.0
Subtracting 142 from 169 leaves us with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
71 goes into 270 3 times with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 3602.3
If we take 213 away from 270, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 8:
The number 71 fits into 570 8 times, leaving a remainder of 2.
The next digit of our result is 8. 
Result so far: 3602.38
If we subtract 568 from 570, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 9:
71 can be fit into 20 0 times, resulting in a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3602.38
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 10:
If we divide 200 by 71, we get 2 and a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 3602.3802
Subtract 142 from 200 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
When dividing 580 by 71, we get 8 with a remainder of 12.
The next digit of our result is 8. 
Result so far: 3602.38028
Deduct 568 from 580 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
71 can be fit into 120 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 3602.380281
Deduct 71 from 120 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 13:
The number 71 fits into 490 6 times, leaving a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 3602.3802816
Subtracting 426 from 490 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 14:
The number 71 fits into 640 9 times, leaving a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 3602.38028169
Subtracting 639 from 640 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 3602.38028169, with a leftover of 1e-09.
