Let's divide 344217 by 81
The aim is to understand the frequency of 81 in 344217.

On to step 1:
3 divided by 81 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 81

On to step 2:
The number 81 fits into 34 0 times, leaving a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 34 to get 34.
Include the next digit (4) from the dividend after 34, then repeat: 344 / 81

Advancing to step 3:
344 divided by 81 is 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 20 after subtracting 324 from 344.
Append the next digit (2) from the dividend to 20 and continue with: 202 / 81

Let's proceed to step 4:
81 goes into 202 2 times with a remainder of 40.
Use 2 as the next digit of our solution. 
Result so far: 42.0
The remainder is 40 after subtracting 162 from 202.
Take the next digit (1) from the dividend and append it to 40, then repeat: 401 / 81

Let's proceed to step 5:
The number 81 fits into 401 4 times, leaving a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 424.0
Subtract 324 from 401 to get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 81

Step 6:
If we divide 777 by 81, we get 9 and a remainder of 48.
Put 9 as the next digit of the answer. 
Result so far: 4249.0
The remainder is 48 after subtracting 729 from 777.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 7:
81 goes into 480 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4249.5
Deduct 405 from 480 and we're left with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 8:
750 divided by 81 is 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 4249.59
Deduct 729 from 750 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
210 divided by 81 is 2 with a remainder of 48.
The number 2 becomes the next digit in our result. 
Result so far: 4249.592
If we subtract 162 from 210, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 10:
When dividing 480 by 81, we get 5 with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 4249.5925
Subtracting 405 from 480 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
81 can be fit into 750 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 4249.59259
Subtract 729 from 750 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 12:
The number 81 fits into 210 2 times, leaving a remainder of 48.
The next digit of our result is 2. 
Result so far: 4249.592592
The remainder is 48 after subtracting 162 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 13:
81 goes into 480 5 times with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 4249.5925925
If we take 405 away from 480, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 4249.59259259
If we subtract 729 from 750, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final result is 4249.59259259 with a remainder of 2.1e-08.
