469575 divided by 90 
The aim is to understand the frequency of 90 in 469575.

Moving on to step 1:
If we divide 4 by 90, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 90

Going ahead to step 2:
90 can be fit into 46 0 times, resulting in a remainder of 46.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 46 to get 46.
Fetch the next digit (9) from the dividend, attach it to 46 and continue: 469 / 90

On to step 3:
90 can be fit into 469 5 times, resulting in a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 450 from 469 to get 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 90

Let's proceed to step 4:
The number 90 fits into 195 2 times, leaving a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 52.0
If we subtract 180 from 195, we get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 90

On to step 5:
157 divided by 90 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 521.0
The remainder is 67 after subtracting 90 from 157.
Take the next digit (5) from the dividend and append it to 67, then repeat: 675 / 90

On to step 6:
If we divide 675 by 90, we get 7 and a remainder of 45.
Put 7 as the next digit of the answer. 
Result so far: 5217.0
The remainder is 45 after subtracting 630 from 675.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 7:
90 can be fit into 450 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5217.5
The remainder is 0 after subtracting 450 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
If we divide 0 by 90, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 5217.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 9:
The number 90 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 5217.5
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 5217.5 with a balance of 0.0.
