129989 divided by 27 
The aim is to understand the frequency of 27 in 129989.

Going ahead to step 1:
1 divided by 27 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 27

Advancing to step 2:
12 divided by 27 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 27

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
Subtracting 108 from 129 leaves us with 21.
Fetch the next digit (9) from the dividend, attach it to 21 and continue: 219 / 27

Advancing to step 4:
27 goes into 219 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 48.0
The remainder is 3 after subtracting 216 from 219.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 27

Advancing to step 5:
38 divided by 27 is 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 481.0
If we take 27 away from 38, we end up with 11.
Take the next digit (9) from the dividend and append it to 11, then repeat: 119 / 27

On to step 6:
27 goes into 119 4 times with a remainder of 11.
Put 4 as the next digit of the answer. 
Result so far: 4814.0
If we subtract 108 from 119, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 27, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 4814.4
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
27 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 4814.4
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
27 goes into 200 7 times with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 4814.407
Deduct 189 from 200 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 10:
When dividing 110 by 27, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 4814.4074
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
27 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4814.4074
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
If we divide 200 by 27, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4814.407407
Subtract 189 from 200 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 13:
The number 27 fits into 110 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 4814.4074074
Subtract 108 from 110 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
The number 27 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 4814.4074074
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 4814.4074074, with a leftover of 2e-08.
