184319 ÷ 90 
The aim is to understand the frequency of 90 in 184319.

Moving on 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
Subtract 0 from 1 to get 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 90

Let's proceed to step 2:
90 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 90

Going ahead to step 3:
The number 90 fits into 184 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 180 from 184 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 90

On to step 4:
When dividing 43 by 90, we get 0 with a remainder of 43.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Subtracting 0 from 43 leaves us with 43.
Grab the next digit (1) from the dividend, add it to 43, then carry on: 431 / 90

Step 5:
The number 90 fits into 431 4 times, leaving a remainder of 71.
Use 4 as the next digit of our solution. 
Result so far: 204.0
The remainder is 71 after subtracting 360 from 431.
Fetch the next digit (9) from the dividend, attach it to 71 and continue: 719 / 90

Let's proceed to step 6:
When dividing 719 by 90, we get 7 with a remainder of 89.
Put 7 as the next digit of the answer. 
Result so far: 2047.0
If we take 630 away from 719, we end up with 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

Step 7:
When dividing 890 by 90, we get 9 with a remainder of 80.
The next digit of our result is 9. 
Result so far: 2047.9
Subtracting 810 from 890 leaves us with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
The number 90 fits into 800 8 times, leaving a remainder of 80.
Write down 8 as next digit of the result. 
Result so far: 2047.98
If we take 720 away from 800, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

On to step 9:
When dividing 800 by 90, we get 8 with a remainder of 80.
The next digit of our result is 8. 
Result so far: 2047.988
If we subtract 720 from 800, we get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

After the division, we end up with 2047.988 and a remainder of 0.008.
