175822 divided by 90 
The aim is to understand the frequency of 90 in 175822.

Advancing to step 1:
The number 90 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 90

Going ahead to step 2:
90 can be fit into 17 0 times, resulting in a remainder of 17.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Append the next digit (5) from the dividend to 17 and continue with: 175 / 90

Moving on to step 3:
If we divide 175 by 90, we get 1 and a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 85 after subtracting 90 from 175.
Fetch the next digit (8) from the dividend, attach it to 85 and continue: 858 / 90

Going ahead to step 4:
858 divided by 90 is 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 48 after subtracting 810 from 858.
Include the next digit (2) from the dividend after 48, then repeat: 482 / 90

Step 5:
90 goes into 482 5 times with a remainder of 32.
Record the quotient 5 as the next digit in the result. 
Result so far: 195.0
Deduct 450 from 482 and we're left with 32.
Fetch the next digit (2) from the dividend, attach it to 32 and continue: 322 / 90

On to step 6:
If we divide 322 by 90, we get 3 and a remainder of 52.
Write down 3 as next digit of the result. 
Result so far: 1953.0
Subtracting 270 from 322 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
If we divide 520 by 90, we get 5 and a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 1953.5
If we take 450 away from 520, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 8:
When dividing 700 by 90, we get 7 with a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 1953.57
Subtracting 630 from 700 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

On to step 9:
90 can be fit into 700 7 times, resulting in a remainder of 70.
Record the quotient 7 as the next digit in the result. 
Result so far: 1953.577
If we take 630 away from 700, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

The final outcome is 1953.577, with a leftover of 0.007.
