We're dividing 794963 by 90 
The aim is to understand the frequency of 90 in 794963.

On to step 1:
90 goes into 7 0 times with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 90

Moving on to step 2:
79 divided by 90 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 79, we get 79.
Take the next digit (4) from the dividend and append it to 79, then repeat: 794 / 90

Going ahead to step 3:
If we divide 794 by 90, we get 8 and a remainder of 74.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Subtract 720 from 794 to get 74.
Grab the next digit (9) from the dividend, add it to 74, then carry on: 749 / 90

Advancing to step 4:
749 divided by 90 is 8 with a remainder of 29.
The next digit of our result is 8. 
Result so far: 88.0
Subtracting 720 from 749 leaves us with 29.
Bring next digit (6) of the dividend behind the 29 and repeat the process: 296 / 90

Advancing to step 5:
296 divided by 90 is 3 with a remainder of 26.
Record the quotient 3 as the next digit in the result. 
Result so far: 883.0
If we subtract 270 from 296, we get 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 90

Step 6:
When dividing 263 by 90, we get 2 with a remainder of 83.
The next digit of our result is 2. 
Result so far: 8832.0
If we take 180 away from 263, we end up with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Let's proceed to step 7:
830 divided by 90 is 9 with a remainder of 20.
Record the quotient 9 as the next digit in the result. 
Result so far: 8832.9
If we subtract 810 from 830, we 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.

Moving on to step 8:
When dividing 200 by 90, we get 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8832.92
If we subtract 180 from 200, we 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.

Advancing to step 9:
200 divided by 90 is 2 with a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 8832.922
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.

Our division results in 8832.922 with a remaining 0.002.
