We're dividing 98463 by 81 
The aim is to understand the frequency of 81 in 98463.

Going ahead to step 1:
The number 81 fits into 9 0 times, leaving a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 81

On to step 2:
81 goes into 98 1 times with a remainder of 17.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 81 away from 98, we end up with 17.
Append the next digit (4) from the dividend to 17 and continue with: 174 / 81

Going ahead to step 3:
The number 81 fits into 174 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
If we subtract 162 from 174, we get 12.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 81

Let's proceed to step 4:
126 divided by 81 is 1 with a remainder of 45.
The number 1 becomes the next digit in our result. 
Result so far: 121.0
Deduct 81 from 126 and we're left with 45.
Include the next digit (3) from the dividend after 45, then repeat: 453 / 81

On to step 5:
If we divide 453 by 81, we get 5 and a remainder of 48.
Put 5 as the next digit of the answer. 
Result so far: 1215.0
Subtracting 405 from 453 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Going ahead to step 6:
480 divided by 81 is 5 with a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1215.5
If we subtract 405 from 480, we get 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 7:
If we divide 750 by 81, we get 9 and a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 1215.59
Subtracting 729 from 750 leaves us 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.

Let's proceed to step 8:
81 goes into 210 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 1215.592
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 9:
The number 81 fits into 480 5 times, leaving a remainder of 75.
Record the quotient 5 as the next digit in the result. 
Result so far: 1215.5925
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.

Step 10:
81 can be fit into 750 9 times, resulting in a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1215.59259
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.

Advancing to step 11:
210 divided by 81 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 1215.592592
If we take 162 away from 210, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
81 goes into 480 5 times with a remainder of 75.
The number 5 becomes the next digit in our result. 
Result so far: 1215.5925925
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.

Step 13:
When dividing 750 by 81, we get 9 with a remainder of 21.
Record the quotient 9 as the next digit in the result. 
Result so far: 1215.59259259
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.

Our division results in 1215.59259259 with a remaining 2.1e-08.
