91072 divided by 71 
The aim is to understand the frequency of 71 in 91072.

Advancing to step 1:
9 divided by 71 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 71

Going ahead to step 2:
91 divided by 71 is 1 with a remainder of 20.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 71 from 91, we get 20.
Append the next digit (0) from the dividend to 20 and continue with: 200 / 71

On to step 3:
71 can be fit into 200 2 times, resulting in a remainder of 58.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 142 from 200 leaves us with 58.
Take the next digit (7) from the dividend and append it to 58, then repeat: 587 / 71

On to step 4:
If we divide 587 by 71, we get 8 and a remainder of 19.
Write down 8 as next digit of the result. 
Result so far: 128.0
Subtracting 568 from 587 leaves us with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 71

Let's proceed to step 5:
71 can be fit into 192 2 times, resulting in a remainder of 50.
Record the quotient 2 as the next digit in the result. 
Result so far: 1282.0
Subtract 142 from 192 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 6:
500 divided by 71 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 1282.7
Deduct 497 from 500 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 7:
71 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 1282.7
The remainder is 30 after subtracting 0 from 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 8:
71 goes into 300 4 times with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 1282.704
The remainder is 16 after subtracting 284 from 300.
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 9:
The number 71 fits into 160 2 times, leaving a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 1282.7042
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.

Advancing to step 10:
The number 71 fits into 180 2 times, leaving a remainder of 38.
The next digit of our result is 2. 
Result so far: 1282.70422
Subtract 142 from 180 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

In conclusion, the division gives 1282.70422 with a balance of 3.8e-05.
