We're dividing 495292 by 90 
The aim is to understand the frequency of 90 in 495292.

Let's proceed to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 90

Step 2:
90 can be fit into 49 0 times, resulting in a remainder of 49.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Bring next digit (5) of the dividend behind the 49 and repeat the process: 495 / 90

On to step 3:
90 can be fit into 495 5 times, resulting in a remainder of 45.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 450 from 495 leaves us with 45.
Take the next digit (2) from the dividend and append it to 45, then repeat: 452 / 90

On to step 4:
The number 90 fits into 452 5 times, leaving a remainder of 2.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Subtract 450 from 452 to get 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 90

Advancing to step 5:
The number 90 fits into 29 0 times, leaving a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 550.0
Deduct 0 from 29 and we're left with 29.
Grab the next digit (2) from the dividend, add it to 29, then carry on: 292 / 90

Let's proceed to step 6:
The number 90 fits into 292 3 times, leaving a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 5503.0
If we take 270 away from 292, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
90 can be fit into 220 2 times, resulting in a remainder of 40.
Put 2 as the next digit of the answer. 
Result so far: 5503.2
Subtracting 180 from 220 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 90 fits into 400 4 times, leaving a remainder of 40.
Record the quotient 4 as the next digit in the result. 
Result so far: 5503.24
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
The number 90 fits into 400 4 times, leaving a remainder of 40.
The next digit of our result is 4. 
Result so far: 5503.244
If we subtract 360 from 400, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 5503.244 with a remainder of 0.004.
