13231884 divided by 45 
The aim is to understand the frequency of 45 in 13231884.

Moving on to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 45

Moving on to step 2:
If we divide 13 by 45, we get 0 and a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 45

On to step 3:
132 divided by 45 is 2 with a remainder of 42.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 90 from 132, we get 42.
Append the next digit (3) from the dividend to 42 and continue with: 423 / 45

Let's proceed to step 4:
When dividing 423 by 45, we get 9 with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 18 after subtracting 405 from 423.
Append the next digit (1) from the dividend to 18 and continue with: 181 / 45

Step 5:
If we divide 181 by 45, we get 4 and a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 294.0
Subtracting 180 from 181 leaves us with 1.
Bring next digit (8) of the dividend behind the 1 and repeat the process: 18 / 45

Going ahead to step 6:
45 can be fit into 18 0 times, resulting in a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 2940.0
The remainder is 18 after subtracting 0 from 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 45

Advancing to step 7:
45 can be fit into 188 4 times, resulting in a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 29404.0
If we subtract 180 from 188, we get 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 45

Let's proceed to step 8:
If we divide 84 by 45, we get 1 and a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 294041.0
If we subtract 45 from 84, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 9:
When dividing 390 by 45, we get 8 with a remainder of 30.
Write down 8 as next digit of the result. 
Result so far: 294041.8
The remainder is 30 after subtracting 360 from 390.
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 10:
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: 294041.86
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.

Advancing to step 11:
When dividing 300 by 45, we get 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 294041.866
If we subtract 270 from 300, we 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.

Our division results in 294041.866 with a remaining 0.003.
