803436 ÷ 27 
The aim is to understand the frequency of 27 in 803436.

Let's proceed to step 1:
27 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 27

Let's proceed to step 2:
The number 27 fits into 80 2 times, leaving a remainder of 26.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 54 from 80 leaves us with 26.
Include the next digit (3) from the dividend after 26, then repeat: 263 / 27

Advancing to step 3:
263 divided by 27 is 9 with a remainder of 20.
The next digit of our result is 9. 
Result so far: 29.0
The remainder is 20 after subtracting 243 from 263.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 27

Advancing to step 4:
The number 27 fits into 204 7 times, leaving a remainder of 15.
Write down 7 as next digit of the result. 
Result so far: 297.0
If we take 189 away from 204, we end up with 15.
Bring next digit (3) of the dividend behind the 15 and repeat the process: 153 / 27

Let's proceed to step 5:
When dividing 153 by 27, we get 5 with a remainder of 18.
Put 5 as the next digit of the answer. 
Result so far: 2975.0
Subtract 135 from 153 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 27

Step 6:
27 goes into 186 6 times with a remainder of 24.
Put 6 as the next digit of the answer. 
Result so far: 29756.0
If we take 162 away from 186, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 7:
When dividing 240 by 27, we get 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 29756.8
Subtracting 216 from 240 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 8:
27 goes into 240 8 times with a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 29756.88
Subtract 216 from 240 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Our division results in 29756.88 with a remaining 0.024.
