Let's divide 330817 by 81
The aim is to understand the frequency of 81 in 330817.

Let's proceed to step 1:
The number 81 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 81

Step 2:
33 divided by 81 is 0 with a remainder of 33.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 33 and we're left with 33.
Bring next digit (0) of the dividend behind the 33 and repeat the process: 330 / 81

Going ahead to step 3:
If we divide 330 by 81, we get 4 and a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 324 from 330 to get 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 81

Moving on to step 4:
If we divide 68 by 81, we get 0 and a remainder of 68.
Use 0 as the next digit of our solution. 
Result so far: 40.0
Subtract 0 from 68 to get 68.
Append the next digit (1) from the dividend to 68 and continue with: 681 / 81

Let's proceed to step 5:
81 goes into 681 8 times with a remainder of 33.
Record the quotient 8 as the next digit in the result. 
Result so far: 408.0
The remainder is 33 after subtracting 648 from 681.
Fetch the next digit (7) from the dividend, attach it to 33 and continue: 337 / 81

On to step 6:
The number 81 fits into 337 4 times, leaving a remainder of 13.
The next digit of our result is 4. 
Result so far: 4084.0
Deduct 324 from 337 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.

Moving on to step 7:
If we divide 130 by 81, we get 1 and a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 4084.1
Deduct 81 from 130 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 8:
When dividing 490 by 81, we get 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 4084.16
If we subtract 486 from 490, we get 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 9:
When dividing 40 by 81, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 4084.16
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 10:
When dividing 400 by 81, we get 4 with a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 4084.1604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
81 goes into 760 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 4084.16049
The remainder is 31 after subtracting 729 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 12:
81 goes into 310 3 times with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 4084.160493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 13:
81 can be fit into 670 8 times, resulting in a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 4084.1604938
Subtract 648 from 670 to 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.

Let's proceed to step 14:
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: 4084.16049382
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

The final result is 4084.16049382 with a remainder of 5.8e-08.
