We divide 384303 by 45
The aim is to understand the frequency of 45 in 384303.

On to step 1:
45 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 45

Advancing to step 2:
The number 45 fits into 38 0 times, leaving a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 38 to get 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 45

Step 3:
45 goes into 384 8 times with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 360 from 384 and we're left with 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 45

Advancing to step 4:
243 divided by 45 is 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 85.0
Subtracting 225 from 243 leaves us with 18.
Fetch the next digit (0) from the dividend, attach it to 18 and continue: 180 / 45

Moving on to step 5:
When dividing 180 by 45, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 854.0
The remainder is 0 after subtracting 180 from 180.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 45

Let's proceed to step 6:
When dividing 3 by 45, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 8540.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
30 divided by 45 is 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 8540.0
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 8:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 8540.06
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
When dividing 300 by 45, we get 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 8540.066
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 8540.066, and the remainder is 0.003.
