We're dividing 215941 by 71 
The aim is to understand the frequency of 71 in 215941.

On to step 1:
71 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 71

Moving on to step 2:
21 divided by 71 is 0 with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 71

Let's proceed to step 3:
The number 71 fits into 215 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 213 from 215 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 71

On to step 4:
When dividing 29 by 71, we get 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 30.0
The remainder is 29 after subtracting 0 from 29.
Bring next digit (4) of the dividend behind the 29 and repeat the process: 294 / 71

Let's proceed to step 5:
294 divided by 71 is 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 304.0
Deduct 284 from 294 and we're left with 10.
Append the next digit (1) from the dividend to 10 and continue with: 101 / 71

Let's proceed to step 6:
If we divide 101 by 71, we get 1 and a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 3041.0
If we subtract 71 from 101, we 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.

Going ahead 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: 3041.4
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.

Going ahead to step 8:
When dividing 160 by 71, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 3041.42
If we subtract 142 from 160, we 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.

Moving on to step 9:
When dividing 180 by 71, we get 2 with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 3041.422
Subtracting 142 from 180 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Our division results in 3041.422 with a remaining 0.0038.
