Let's divide 895574 by 90
The aim is to understand the frequency of 90 in 895574.

Moving on to step 1:
90 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 90

Let's proceed to step 2:
90 goes into 89 0 times with a remainder of 89.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 89, we get 89.
Include the next digit (5) from the dividend after 89, then repeat: 895 / 90

Going ahead to step 3:
The number 90 fits into 895 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 810 from 895 to get 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 90

Step 4:
90 goes into 855 9 times with a remainder of 45.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 810 from 855 and we're left with 45.
Fetch the next digit (7) from the dividend, attach it to 45 and continue: 457 / 90

Going ahead to step 5:
The number 90 fits into 457 5 times, leaving a remainder of 7.
The next digit of our result is 5. 
Result so far: 995.0
If we subtract 450 from 457, we get 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 90

Going ahead to step 6:
The number 90 fits into 74 0 times, leaving a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 9950.0
Subtract 0 from 74 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 7:
90 goes into 740 8 times with a remainder of 20.
The next digit of our result is 8. 
Result so far: 9950.8
The remainder is 20 after subtracting 720 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
90 goes into 200 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 9950.82
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
The number 90 fits into 200 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 9950.822
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.

After the division, we end up with 9950.822 and a remainder of 0.002.
