903669 ÷ 27 
The aim is to understand the frequency of 27 in 903669.

Step 1:
When dividing 9 by 27, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 27

Let's proceed to step 2:
27 goes into 90 3 times with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 81 from 90 leaves us with 9.
Include the next digit (3) from the dividend after 9, then repeat: 93 / 27

Going ahead to step 3:
When dividing 93 by 27, we get 3 with a remainder of 12.
Record the quotient 3 as the next digit in the result. 
Result so far: 33.0
Subtracting 81 from 93 leaves us with 12.
Fetch the next digit (6) from the dividend, attach it to 12 and continue: 126 / 27

On to step 4:
126 divided by 27 is 4 with a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 334.0
Deduct 108 from 126 and we're left with 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 27

On to step 5:
27 goes into 186 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 3346.0
Subtract 162 from 186 to get 24.
Take the next digit (9) from the dividend and append it to 24, then repeat: 249 / 27

Let's proceed to step 6:
If we divide 249 by 27, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 33469.0
Deduct 243 from 249 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
The number 27 fits into 60 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 33469.2
The remainder is 6 after subtracting 54 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
The number 27 fits into 60 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 33469.22
Subtracting 54 from 60 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 33469.22 with a remaining 0.006.
