326610 divided by 81 
The aim is to understand the frequency of 81 in 326610.

Step 1:
81 can be fit into 3 0 times, resulting in a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (2) from the dividend after 3, then repeat: 32 / 81

Moving on to step 2:
81 goes into 32 0 times with a remainder of 32.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Grab the next digit (6) from the dividend, add it to 32, then carry on: 326 / 81

Moving on to step 3:
326 divided by 81 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 324 from 326 and we're left with 2.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 81

On to step 4:
The number 81 fits into 26 0 times, leaving a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 26, we end up with 26.
Bring next digit (1) of the dividend behind the 26 and repeat the process: 261 / 81

On to step 5:
If we divide 261 by 81, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we subtract 243 from 261, we get 18.
Append the next digit (0) from the dividend to 18 and continue with: 180 / 81

Going ahead to step 6:
180 divided by 81 is 2 with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 4032.0
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.

Let's proceed to step 7:
81 can be fit into 180 2 times, resulting in a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 4032.2
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.

Moving on to step 8:
When dividing 180 by 81, we get 2 with a remainder of 18.
Put 2 as the next digit of the answer. 
Result so far: 4032.22
Subtracting 162 from 180 leaves us 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.

In conclusion, the division gives 4032.22 with a balance of 0.018.
