We divide 265791 by 90
The aim is to understand the frequency of 90 in 265791.

Going ahead to step 1:
When dividing 2 by 90, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 90

Step 2:
90 goes into 26 0 times with a remainder of 26.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 26 after subtracting 0 from 26.
Fetch the next digit (5) from the dividend, attach it to 26 and continue: 265 / 90

Going ahead to step 3:
When dividing 265 by 90, we get 2 with a remainder of 85.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 180 from 265 to get 85.
Include the next digit (7) from the dividend after 85, then repeat: 857 / 90

Advancing to step 4:
857 divided by 90 is 9 with a remainder of 47.
Write down 9 as next digit of the result. 
Result so far: 29.0
Subtracting 810 from 857 leaves us with 47.
Include the next digit (9) from the dividend after 47, then repeat: 479 / 90

Moving on to step 5:
90 goes into 479 5 times with a remainder of 29.
Write down 5 as next digit of the result. 
Result so far: 295.0
The remainder is 29 after subtracting 450 from 479.
Append the next digit (1) from the dividend to 29 and continue with: 291 / 90

Going ahead to step 6:
291 divided by 90 is 3 with a remainder of 21.
The next digit of our result is 3. 
Result so far: 2953.0
If we subtract 270 from 291, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
210 divided by 90 is 2 with a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 2953.2
If we subtract 180 from 210, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
When dividing 300 by 90, we get 3 with a remainder of 30.
The next digit of our result is 3. 
Result so far: 2953.23
If we take 270 away from 300, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 90, we get 3 with a remainder of 30.
Put 3 as the next digit of the answer. 
Result so far: 2953.233
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 2953.233 with a remaining 0.003.
