Let's divide 978988 by 27
The aim is to understand the frequency of 27 in 978988.

Step 1:
If we divide 9 by 27, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Append the next digit (7) from the dividend to 9 and continue with: 97 / 27

Going ahead to step 2:
97 divided by 27 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 81 from 97 to get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 27

Step 3:
27 goes into 168 6 times with a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtracting 162 from 168 leaves us with 6.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 27

Going ahead to step 4:
27 can be fit into 69 2 times, resulting in a remainder of 15.
The next digit of our result is 2. 
Result so far: 362.0
Subtracting 54 from 69 leaves us with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 27

On to step 5:
27 can be fit into 158 5 times, resulting in a remainder of 23.
Use 5 as the next digit of our solution. 
Result so far: 3625.0
Subtract 135 from 158 to get 23.
Include the next digit (8) from the dividend after 23, then repeat: 238 / 27

Going ahead to step 6:
238 divided by 27 is 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 36258.0
The remainder is 22 after subtracting 216 from 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 7:
27 goes into 220 8 times with a remainder of 4.
The next digit of our result is 8. 
Result so far: 36258.8
Subtracting 216 from 220 leaves us 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.

Going ahead to step 8:
27 goes into 40 1 times with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 36258.81
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 9:
27 goes into 130 4 times with a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 36258.814
Deduct 108 from 130 and we're left 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.

Moving on to step 10:
If we divide 220 by 27, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 36258.8148
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.

Going ahead to step 11:
27 can be fit into 40 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 36258.81481
The remainder is 13 after subtracting 27 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 12:
27 can be fit into 130 4 times, resulting in a remainder of 22.
The next digit of our result is 4. 
Result so far: 36258.814814
If we take 108 away from 130, we end up 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 13:
27 can be fit into 220 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 36258.8148148
Subtracting 216 from 220 leaves us 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.

Let's proceed to step 14:
When dividing 40 by 27, we get 1 with a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 36258.81481481
If we take 27 away from 40, we end up 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 36258.81481481 with a balance of 1.3e-08.
