We look at the division of 981646 by 71 
The aim is to understand the frequency of 71 in 981646.

Let's proceed to step 1:
71 can be fit into 9 0 times, resulting in a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Take the next digit (8) from the dividend and append it to 9, then repeat: 98 / 71

On to step 2:
71 can be fit into 98 1 times, resulting in a remainder of 27.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 27 after subtracting 71 from 98.
Include the next digit (1) from the dividend after 27, then repeat: 271 / 71

Moving on to step 3:
71 goes into 271 3 times with a remainder of 58.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
Deduct 213 from 271 and we're left with 58.
Include the next digit (6) from the dividend after 58, then repeat: 586 / 71

Step 4:
If we divide 586 by 71, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 138.0
Subtract 568 from 586 to get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 71

Going ahead to step 5:
184 divided by 71 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 1382.0
The remainder is 42 after subtracting 142 from 184.
Bring next digit (6) of the dividend behind the 42 and repeat the process: 426 / 71

On to step 6:
If we divide 426 by 71, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 13826.0
Deduct 426 from 426 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 7:
71 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 13826.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 71 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13826.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 13826.0, with a leftover of 0.0.
