We're dividing 234502 by 81 
The aim is to understand the frequency of 81 in 234502.

Let's proceed to step 1:
2 divided by 81 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 81

Let's proceed to step 2:
The number 81 fits into 23 0 times, leaving a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 23, we end up with 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 81

On to step 3:
The number 81 fits into 234 2 times, leaving a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 162 from 234, we get 72.
Include the next digit (5) from the dividend after 72, then repeat: 725 / 81

On to step 4:
The number 81 fits into 725 8 times, leaving a remainder of 77.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
The remainder is 77 after subtracting 648 from 725.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 81

Advancing to step 5:
The number 81 fits into 770 9 times, leaving a remainder of 41.
Record the quotient 9 as the next digit in the result. 
Result so far: 289.0
Deduct 729 from 770 and we're left with 41.
Take the next digit (2) from the dividend and append it to 41, then repeat: 412 / 81

Moving on to step 6:
When dividing 412 by 81, we get 5 with a remainder of 7.
Record the quotient 5 as the next digit in the result. 
Result so far: 2895.0
If we take 405 away from 412, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
The number 81 fits into 70 0 times, leaving a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 2895.0
If we take 0 away from 70, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 81, we get 8 with a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 2895.08
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 9:
If we divide 520 by 81, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 2895.086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
340 divided by 81 is 4 with a remainder of 16.
Write down 4 as next digit of the result. 
Result so far: 2895.0864
Subtract 324 from 340 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
If we divide 160 by 81, we get 1 and a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 2895.08641
Subtract 81 from 160 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 12:
81 can be fit into 790 9 times, resulting in a remainder of 61.
Put 9 as the next digit of the answer. 
Result so far: 2895.086419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Advancing to step 13:
81 goes into 610 7 times with a remainder of 43.
Put 7 as the next digit of the answer. 
Result so far: 2895.0864197
The remainder is 43 after subtracting 567 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 14:
81 goes into 430 5 times with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 2895.08641975
Deduct 405 from 430 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 2895.08641975 with a balance of 2.5e-08.
