We're dividing 973457 by 71 
The aim is to understand the frequency of 71 in 973457.

Going ahead to step 1:
71 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 71

Moving on to step 2:
71 goes into 97 1 times with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 71 from 97 leaves us with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 71

On to step 3:
263 divided by 71 is 3 with a remainder of 50.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Deduct 213 from 263 and we're left with 50.
Take the next digit (4) from the dividend and append it to 50, then repeat: 504 / 71

Advancing to step 4:
The number 71 fits into 504 7 times, leaving a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 137.0
The remainder is 7 after subtracting 497 from 504.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 71

Let's proceed to step 5:
71 can be fit into 75 1 times, resulting in a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 1371.0
If we subtract 71 from 75, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 71

Going ahead to step 6:
If we divide 47 by 71, we get 0 and a remainder of 47.
The next digit of our result is 0. 
Result so far: 13710.0
If we subtract 0 from 47, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Let's proceed to step 7:
71 can be fit into 470 6 times, resulting in a remainder of 44.
The next digit of our result is 6. 
Result so far: 13710.6
Deduct 426 from 470 and we're left with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 71 fits into 440 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 13710.66
Subtract 426 from 440 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The quotient of the division is 13710.66, and the remainder is 0.014.
