We look at the division of 132445 by 71 
The aim is to understand the frequency of 71 in 132445.

Let's proceed to step 1:
1 divided by 71 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 71

Let's proceed to step 2:
The number 71 fits into 13 0 times, leaving a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Bring next digit (2) of the dividend behind the 13 and repeat the process: 132 / 71

On to step 3:
71 goes into 132 1 times with a remainder of 61.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 71 from 132 leaves us with 61.
Bring next digit (4) of the dividend behind the 61 and repeat the process: 614 / 71

Advancing to step 4:
71 goes into 614 8 times with a remainder of 46.
The next digit of our result is 8. 
Result so far: 18.0
Deduct 568 from 614 and we're left with 46.
Take the next digit (4) from the dividend and append it to 46, then repeat: 464 / 71

Advancing to step 5:
71 goes into 464 6 times with a remainder of 38.
Use 6 as the next digit of our solution. 
Result so far: 186.0
If we take 426 away from 464, we end up with 38.
Bring next digit (5) of the dividend behind the 38 and repeat the process: 385 / 71

Let's proceed to step 6:
71 goes into 385 5 times with a remainder of 30.
The next digit of our result is 5. 
Result so far: 1865.0
Subtract 355 from 385 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 71, we get 4 and a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 1865.4
Subtracting 284 from 300 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 8:
If we divide 160 by 71, we get 2 and a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 1865.42
Subtract 142 from 160 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
When dividing 180 by 71, we get 2 with a remainder of 38.
The next digit of our result is 2. 
Result so far: 1865.422
The remainder is 38 after subtracting 142 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 1865.422, and the remainder is 0.0038.
