Let's divide 27306 by 90
The aim is to understand the frequency of 90 in 27306.

Moving on to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 90

Moving on to step 2:
If we divide 27 by 90, we get 0 and a remainder of 27.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 90

Advancing to step 3:
273 divided by 90 is 3 with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 270 from 273 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 90

Step 4:
If we divide 30 by 90, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 30, we end up with 30.
Include the next digit (6) from the dividend after 30, then repeat: 306 / 90

On to step 5:
306 divided by 90 is 3 with a remainder of 36.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
If we take 270 away from 306, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 6:
90 goes into 360 4 times with a remainder of 0.
The next digit of our result is 4. 
Result so far: 303.4
If we subtract 360 from 360, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 7:
If we divide 0 by 90, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 303.4
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 303.4
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 303.4, with a leftover of 0.0.
