We're dividing 713610 by 81 
The aim is to understand the frequency of 81 in 713610.

Advancing to step 1:
81 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (1) from the dividend after 7, then repeat: 71 / 81

Moving on to step 2:
If we divide 71 by 81, we get 0 and a remainder of 71.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 71, we get 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 81

Step 3:
If we divide 713 by 81, we get 8 and a remainder of 65.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we take 648 away from 713, we end up with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 81

Moving on to step 4:
656 divided by 81 is 8 with a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 88.0
The remainder is 8 after subtracting 648 from 656.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 81

Step 5:
81 goes into 81 1 times with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 881.0
Subtracting 81 from 81 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 81

Going ahead to step 6:
If we divide 0 by 81, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8810.0
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.

On to step 7:
If we divide 0 by 81, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8810.0
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.

Let's proceed to step 8:
If we divide 0 by 81, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 8810.0
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.

After the division, we end up with 8810.0 and a remainder of 0.0.
