We look at the division of 378089 by 27 
The aim is to understand the frequency of 27 in 378089.

Let's proceed to step 1:
27 goes into 3 0 times with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 27

Advancing to step 2:
27 goes into 37 1 times with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 10 after subtracting 27 from 37.
Include the next digit (8) from the dividend after 10, then repeat: 108 / 27

Let's proceed to step 3:
The number 27 fits into 108 4 times, leaving a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 14.0
Subtracting 108 from 108 leaves us with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 27

Moving on to step 4:
27 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 140.0
If we take 0 away from 0, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 27

Step 5:
27 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 1400.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 27

Advancing to step 6:
89 divided by 27 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 14003.0
Deduct 81 from 89 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 7:
27 can be fit into 80 2 times, resulting in a remainder of 26.
The next digit of our result is 2. 
Result so far: 14003.2
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
27 can be fit into 260 9 times, resulting in a remainder of 17.
The next digit of our result is 9. 
Result so far: 14003.29
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
27 can be fit into 170 6 times, resulting in a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 14003.296
Subtract 162 from 170 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 10:
The number 27 fits into 80 2 times, leaving a remainder of 26.
The number 2 becomes the next digit in our result. 
Result so far: 14003.2962
The remainder is 26 after subtracting 54 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 11:
The number 27 fits into 260 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 14003.29629
Deduct 243 from 260 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 12:
27 can be fit into 170 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 14003.296296
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
80 divided by 27 is 2 with a remainder of 26.
Use 2 as the next digit of our solution. 
Result so far: 14003.2962962
Deduct 54 from 80 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 14:
27 goes into 260 9 times with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 14003.29629629
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

After the division, we end up with 14003.29629629 and a remainder of 1.7e-08.
