Let's divide 129817 by 27
The aim is to understand the frequency of 27 in 129817.

Going ahead to step 1:
When dividing 1 by 27, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 27

Let's proceed to step 2:
12 divided by 27 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 12 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 27

Let's proceed to step 3:
27 can be fit into 129 4 times, resulting in a remainder of 21.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 108 from 129, we get 21.
Grab the next digit (8) from the dividend, add it to 21, then carry on: 218 / 27

Going ahead to step 4:
27 goes into 218 8 times with a remainder of 2.
The next digit of our result is 8. 
Result so far: 48.0
Deduct 216 from 218 and we're left with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 27

Step 5:
When dividing 21 by 27, we get 0 with a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 480.0
Subtracting 0 from 21 leaves us with 21.
Fetch the next digit (7) from the dividend, attach it to 21 and continue: 217 / 27

Going ahead to step 6:
The number 27 fits into 217 8 times, leaving a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 4808.0
If we subtract 216 from 217, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
27 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4808.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
100 divided by 27 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 4808.03
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 9:
27 goes into 190 7 times with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 4808.037
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 10:
When dividing 10 by 27, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4808.037
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
If we divide 100 by 27, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 4808.03703
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 12:
190 divided by 27 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 4808.037037
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
10 divided by 27 is 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4808.037037
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 14:
If we divide 100 by 27, we get 3 and a remainder of 19.
The number 3 becomes the next digit in our result. 
Result so far: 4808.03703703
Subtracting 81 from 100 leaves us with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Our division results in 4808.03703703 with a remaining 1.9e-08.
