We look at the division of 262046 by 90 
The aim is to understand the frequency of 90 in 262046.

On to step 1:
2 divided by 90 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 90

Going ahead to step 2:
90 goes into 26 0 times with a remainder of 26.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (2) of the dividend behind the 26 and repeat the process: 262 / 90

Let's proceed to step 3:
The number 90 fits into 262 2 times, leaving a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 180 away from 262, we end up with 82.
Include the next digit (0) from the dividend after 82, then repeat: 820 / 90

Moving on to step 4:
The number 90 fits into 820 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 29.0
Subtracting 810 from 820 leaves us with 10.
Fetch the next digit (4) from the dividend, attach it to 10 and continue: 104 / 90

On to step 5:
104 divided by 90 is 1 with a remainder of 14.
The next digit of our result is 1. 
Result so far: 291.0
Subtracting 90 from 104 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 90

Step 6:
When dividing 146 by 90, we get 1 with a remainder of 56.
Use 1 as the next digit of our solution. 
Result so far: 2911.0
Subtracting 90 from 146 leaves us with 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Moving on to step 7:
90 can be fit into 560 6 times, resulting in a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 2911.6
If we take 540 away from 560, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 8:
200 divided by 90 is 2 with a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 2911.62
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
Record the quotient 2 as the next digit in the result. 
Result so far: 2911.622
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 2911.622, and the remainder is 0.002.
