We're dividing 11994 by 45 
The aim is to understand the frequency of 45 in 11994.

Going ahead to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 45

Let's proceed to step 2:
45 goes into 11 0 times with a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 11 after subtracting 0 from 11.
Bring next digit (9) of the dividend behind the 11 and repeat the process: 119 / 45

Moving on to step 3:
If we divide 119 by 45, we get 2 and a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 90 from 119, we get 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 45

Let's proceed to step 4:
45 can be fit into 299 6 times, resulting in a remainder of 29.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtracting 270 from 299 leaves us with 29.
Fetch the next digit (4) from the dividend, attach it to 29 and continue: 294 / 45

Going ahead to step 5:
45 goes into 294 6 times with a remainder of 24.
Write down 6 as next digit of the result. 
Result so far: 266.0
If we take 270 away from 294, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 6:
The number 45 fits into 240 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 266.5
Deduct 225 from 240 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
150 divided by 45 is 3 with a remainder of 15.
Put 3 as the next digit of the answer. 
Result so far: 266.53
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 266.533
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final outcome is 266.533, with a leftover of 0.0015.
