We divide 8867 by 90
The aim is to understand the frequency of 90 in 8867.

Let's proceed to step 1:
If we divide 8 by 90, we get 0 and a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 90

Moving on to step 2:
90 can be fit into 88 0 times, resulting in a remainder of 88.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 88, we get 88.
Take the next digit (6) from the dividend and append it to 88, then repeat: 886 / 90

Going ahead to step 3:
If we divide 886 by 90, we get 9 and a remainder of 76.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 810 from 886 leaves us with 76.
Include the next digit (7) from the dividend after 76, then repeat: 767 / 90

Going ahead to step 4:
767 divided by 90 is 8 with a remainder of 47.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
Subtracting 720 from 767 leaves us with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 5:
When dividing 470 by 90, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 98.5
The remainder is 20 after subtracting 450 from 470.
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 6:
90 goes into 200 2 times with a remainder of 20.
The next digit of our result is 2. 
Result so far: 98.52
Subtract 180 from 200 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
200 divided by 90 is 2 with a remainder of 20.
The next digit of our result is 2. 
Result so far: 98.522
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.

The quotient of the division is 98.522, and the remainder is 0.002.
