We're dividing 25142911 by 27 
The aim is to understand the frequency of 27 in 25142911.

Step 1:
When dividing 2 by 27, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 27

Step 2:
When dividing 25 by 27, we get 0 with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 27

On to step 3:
27 can be fit into 251 9 times, resulting in a remainder of 8.
The next digit of our result is 9. 
Result so far: 9.0
Deduct 243 from 251 and we're left with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 27

Let's proceed to step 4:
The number 27 fits into 84 3 times, leaving a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 93.0
If we subtract 81 from 84, we get 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 27

Going ahead to step 5:
27 can be fit into 32 1 times, resulting in a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 931.0
If we subtract 27 from 32, we get 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 27

On to step 6:
27 can be fit into 59 2 times, resulting in a remainder of 5.
Write down 2 as next digit of the result. 
Result so far: 9312.0
If we take 54 away from 59, we end up with 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 27

Advancing to step 7:
The number 27 fits into 51 1 times, leaving a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 93121.0
If we subtract 27 from 51, we get 24.
Grab the next digit (1) from the dividend, add it to 24, then carry on: 241 / 27

Let's proceed to step 8:
When dividing 241 by 27, we get 8 with a remainder of 25.
Use 8 as the next digit of our solution. 
Result so far: 931218.0
The remainder is 25 after subtracting 216 from 241.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 9:
250 divided by 27 is 9 with a remainder of 7.
The next digit of our result is 9. 
Result so far: 931218.9
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 10:
The number 27 fits into 70 2 times, leaving a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 931218.92
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 11:
27 goes into 160 5 times with a remainder of 25.
The next digit of our result is 5. 
Result so far: 931218.925
If we take 135 away from 160, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 12:
The number 27 fits into 250 9 times, leaving a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 931218.9259
Deduct 243 from 250 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 13:
27 goes into 70 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 931218.92592
Subtracting 54 from 70 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 14:
When dividing 160 by 27, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 931218.925925
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 15:
250 divided by 27 is 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 931218.9259259
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 16:
70 divided by 27 is 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 931218.92592592
If we take 54 away from 70, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 931218.92592592, and the remainder is 1.6e-08.
