We divide 389805 by 71
The aim is to understand the frequency of 71 in 389805.

Moving on to step 1:
71 can be fit into 3 0 times, resulting in a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 71

Let's proceed to step 2:
38 divided by 71 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 71

Going ahead to step 3:
When dividing 389 by 71, we get 5 with a remainder of 34.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we subtract 355 from 389, we get 34.
Bring next digit (8) of the dividend behind the 34 and repeat the process: 348 / 71

On to step 4:
When dividing 348 by 71, we get 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 54.0
If we subtract 284 from 348, we get 64.
Bring next digit (0) of the dividend behind the 64 and repeat the process: 640 / 71

Moving on to step 5:
The number 71 fits into 640 9 times, leaving a remainder of 1.
The next digit of our result is 9. 
Result so far: 549.0
If we take 639 away from 640, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 71

On to step 6:
71 can be fit into 15 0 times, resulting in a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 5490.0
If we subtract 0 from 15, 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 7:
71 can be fit into 150 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 5490.2
Subtracting 142 from 150 leaves us 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 8:
71 goes into 80 1 times with a remainder of 9.
The next digit of our result is 1. 
Result so far: 5490.21
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 9:
71 goes into 90 1 times with a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 5490.211
If we take 71 away from 90, we end up 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 result is 5490.211 with a remainder of 0.0019.
