Let's divide 474899 by 90
The aim is to understand the frequency of 90 in 474899.

Step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 90

Going ahead to step 2:
90 goes into 47 0 times with a remainder of 47.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 47 after subtracting 0 from 47.
Bring next digit (4) of the dividend behind the 47 and repeat the process: 474 / 90

Moving on to step 3:
The number 90 fits into 474 5 times, leaving a remainder of 24.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 450 away from 474, we end up with 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 90

On to step 4:
The number 90 fits into 248 2 times, leaving a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 180 from 248, we get 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 90

Moving on to step 5:
689 divided by 90 is 7 with a remainder of 59.
The next digit of our result is 7. 
Result so far: 527.0
If we subtract 630 from 689, we get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 90

Step 6:
599 divided by 90 is 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 5276.0
If we subtract 540 from 599, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 7:
90 can be fit into 590 6 times, resulting in a remainder of 50.
Put 6 as the next digit of the answer. 
Result so far: 5276.6
Subtracting 540 from 590 leaves us with 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:
If we divide 500 by 90, we get 5 and a remainder of 50.
The next digit of our result is 5. 
Result so far: 5276.65
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.

Let's proceed to step 9:
When dividing 500 by 90, we get 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 5276.655
The remainder is 50 after subtracting 450 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Our division results in 5276.655 with a remaining 0.005.
