We look at the division of 259601 by 71 
The aim is to understand the frequency of 71 in 259601.

Going ahead to step 1:
71 can be fit into 2 0 times, resulting in a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 71

Advancing to step 2:
When dividing 25 by 71, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 71

On to step 3:
When dividing 259 by 71, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 46 after subtracting 213 from 259.
Take the next digit (6) from the dividend and append it to 46, then repeat: 466 / 71

Step 4:
71 can be fit into 466 6 times, resulting in a remainder of 40.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 426 from 466 to get 40.
Take the next digit (0) from the dividend and append it to 40, then repeat: 400 / 71

Moving on to step 5:
71 goes into 400 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 365.0
Subtracting 355 from 400 leaves us with 45.
Bring next digit (1) of the dividend behind the 45 and repeat the process: 451 / 71

Going ahead to step 6:
71 can be fit into 451 6 times, resulting in a remainder of 25.
The number 6 becomes the next digit in our result. 
Result so far: 3656.0
If we take 426 away from 451, we end up 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.

Let's proceed to step 7:
If we divide 250 by 71, we get 3 and a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 3656.3
If we take 213 away from 250, we end up 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.

Going ahead to step 8:
71 goes into 370 5 times with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 3656.35
If we subtract 355 from 370, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
The number 71 fits into 150 2 times, leaving a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 3656.352
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.

Moving on to step 10:
If we divide 80 by 71, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 3656.3521
If we take 71 away from 80, we end up 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.

On to step 11:
The number 71 fits into 90 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 3656.35211
Subtract 71 from 90 to 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.

The final result is 3656.35211 with a remainder of 1.9e-05.
