268259 divided by 90 
The aim is to understand the frequency of 90 in 268259.

Going ahead to step 1:
90 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 90

Let's proceed to step 2:
When dividing 26 by 90, we get 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 26 leaves us with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 90

Moving on to step 3:
When dividing 268 by 90, we get 2 with a remainder of 88.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 180 from 268 to get 88.
Include the next digit (2) from the dividend after 88, then repeat: 882 / 90

On to step 4:
90 goes into 882 9 times with a remainder of 72.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtracting 810 from 882 leaves us with 72.
Fetch the next digit (5) from the dividend, attach it to 72 and continue: 725 / 90

Let's proceed to step 5:
If we divide 725 by 90, we get 8 and a remainder of 5.
The next digit of our result is 8. 
Result so far: 298.0
Deduct 720 from 725 and we're left with 5.
Include the next digit (9) from the dividend after 5, then repeat: 59 / 90

Advancing to step 6:
90 goes into 59 0 times with a remainder of 59.
Write down 0 as next digit of the result. 
Result so far: 2980.0
Deduct 0 from 59 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 7:
90 can be fit into 590 6 times, resulting in a remainder of 50.
Use 6 as the next digit of our solution. 
Result so far: 2980.6
If we subtract 540 from 590, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 8:
When dividing 500 by 90, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 2980.65
If we subtract 450 from 500, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 9:
90 goes into 500 5 times with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 2980.655
Subtract 450 from 500 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final result is 2980.655 with a remainder of 0.005.
