We divide 194443 by 45
The aim is to understand the frequency of 45 in 194443.

Let's proceed to step 1:
If we divide 1 by 45, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 45

Step 2:
The number 45 fits into 19 0 times, leaving a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 19 after subtracting 0 from 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 45

Moving on to step 3:
45 can be fit into 194 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 14 after subtracting 180 from 194.
Fetch the next digit (4) from the dividend, attach it to 14 and continue: 144 / 45

Step 4:
The number 45 fits into 144 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 43.0
Subtracting 135 from 144 leaves us with 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 45

Advancing to step 5:
45 goes into 94 2 times with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 432.0
Subtracting 90 from 94 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 45

Going ahead to step 6:
43 divided by 45 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 4320.0
The remainder is 43 after subtracting 0 from 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 7:
45 goes into 430 9 times with a remainder of 25.
Write down 9 as next digit of the result. 
Result so far: 4320.9
The remainder is 25 after subtracting 405 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4320.95
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
45 goes into 250 5 times with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 4320.955
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 4320.955 and a remainder of 0.0025.
