We divide 232906 by 81
The aim is to understand the frequency of 81 in 232906.

Advancing to step 1:
The number 81 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 81

Advancing to step 2:
The number 81 fits into 23 0 times, leaving a remainder of 23.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Fetch the next digit (2) from the dividend, attach it to 23 and continue: 232 / 81

Advancing to step 3:
If we divide 232 by 81, we get 2 and a remainder of 70.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 162 from 232 to get 70.
Bring next digit (9) of the dividend behind the 70 and repeat the process: 709 / 81

Step 4:
709 divided by 81 is 8 with a remainder of 61.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 648 away from 709, we end up with 61.
Bring next digit (0) of the dividend behind the 61 and repeat the process: 610 / 81

Step 5:
If we divide 610 by 81, we get 7 and a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 287.0
Subtracting 567 from 610 leaves us with 43.
Include the next digit (6) from the dividend after 43, then repeat: 436 / 81

Step 6:
The number 81 fits into 436 5 times, leaving a remainder of 31.
Write down 5 as next digit of the result. 
Result so far: 2875.0
The remainder is 31 after subtracting 405 from 436.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 7:
310 divided by 81 is 3 with a remainder of 67.
The next digit of our result is 3. 
Result so far: 2875.3
Subtract 243 from 310 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 8:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 2875.38
If we subtract 648 from 670, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 9:
The number 81 fits into 220 2 times, leaving a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 2875.382
If we take 162 away from 220, we end up with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 10:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 2875.3827
Deduct 567 from 580 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 11:
The number 81 fits into 130 1 times, leaving a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 2875.38271
The remainder is 49 after subtracting 81 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 12:
81 goes into 490 6 times with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 2875.382716
If we take 486 away from 490, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 13:
The number 81 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 2875.382716
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 14:
When dividing 400 by 81, we get 4 with a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 2875.38271604
If we subtract 324 from 400, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Our division results in 2875.38271604 with a remaining 7.6e-08.
