We're dividing 314541 by 81 
The aim is to understand the frequency of 81 in 314541.

Moving on to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (1) of the dividend behind the 3 and repeat the process: 31 / 81

Going ahead to step 2:
81 goes into 31 0 times with a remainder of 31.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 31, we get 31.
Bring next digit (4) of the dividend behind the 31 and repeat the process: 314 / 81

Advancing to step 3:
If we divide 314 by 81, we get 3 and a remainder of 71.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 243 away from 314, we end up with 71.
Take the next digit (5) from the dividend and append it to 71, then repeat: 715 / 81

Step 4:
The number 81 fits into 715 8 times, leaving a remainder of 67.
Put 8 as the next digit of the answer. 
Result so far: 38.0
Subtracting 648 from 715 leaves us with 67.
Take the next digit (4) from the dividend and append it to 67, then repeat: 674 / 81

Step 5:
674 divided by 81 is 8 with a remainder of 26.
Use 8 as the next digit of our solution. 
Result so far: 388.0
Subtract 648 from 674 to get 26.
Fetch the next digit (1) from the dividend, attach it to 26 and continue: 261 / 81

Going ahead to step 6:
81 can be fit into 261 3 times, resulting in a remainder of 18.
Use 3 as the next digit of our solution. 
Result so far: 3883.0
Deduct 243 from 261 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
180 divided by 81 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 3883.2
If we subtract 162 from 180, 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.

Going ahead to step 8:
180 divided by 81 is 2 with a remainder of 18.
The next digit of our result is 2. 
Result so far: 3883.22
If we take 162 away from 180, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 3883.22 with a remaining 0.018.
