We're dividing 12529966 by 27 
The aim is to understand the frequency of 27 in 12529966.

Advancing to step 1:
The number 27 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 27

Let's proceed to step 2:
If we divide 12 by 27, we get 0 and a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 27

Going ahead to step 3:
The number 27 fits into 125 4 times, leaving a remainder of 17.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 108 from 125 to get 17.
Include the next digit (2) from the dividend after 17, then repeat: 172 / 27

Going ahead to step 4:
172 divided by 27 is 6 with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 46.0
Deduct 162 from 172 and we're left with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 27

Going ahead to step 5:
27 can be fit into 109 4 times, resulting in a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 464.0
Subtract 108 from 109 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 27

Advancing to step 6:
When dividing 19 by 27, we get 0 with a remainder of 19.
The next digit of our result is 0. 
Result so far: 4640.0
The remainder is 19 after subtracting 0 from 19.
Take the next digit (6) from the dividend and append it to 19, then repeat: 196 / 27

On to step 7:
196 divided by 27 is 7 with a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 46407.0
Subtracting 189 from 196 leaves us with 7.
Fetch the next digit (6) from the dividend, attach it to 7 and continue: 76 / 27

Step 8:
The number 27 fits into 76 2 times, leaving a remainder of 22.
The next digit of our result is 2. 
Result so far: 464072.0
Subtract 54 from 76 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.

Advancing to step 9:
If we divide 220 by 27, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 464072.8
Subtract 216 from 220 to 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.

Advancing to step 10:
When dividing 40 by 27, we get 1 with a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 464072.81
Subtracting 27 from 40 leaves us 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.

Going ahead to step 11:
27 goes into 130 4 times with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 464072.814
Subtracting 108 from 130 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 12:
If we divide 220 by 27, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 464072.8148
Subtract 216 from 220 to 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 13:
27 goes into 40 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 464072.81481
If we subtract 27 from 40, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
When dividing 130 by 27, we get 4 with a remainder of 22.
The next digit of our result is 4. 
Result so far: 464072.814814
Subtract 108 from 130 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.

Advancing to step 15:
220 divided by 27 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 464072.8148148
If we take 216 away from 220, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 16:
If we divide 40 by 27, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 464072.81481481
Subtracting 27 from 40 leaves us 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.

In conclusion, the division gives 464072.81481481 with a balance of 1.3e-08.
