184781 ÷ 45 
The aim is to understand the frequency of 45 in 184781.

Step 1:
The number 45 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 45

Step 2:
18 divided by 45 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 18 to get 18.
Take the next digit (4) from the dividend and append it to 18, then repeat: 184 / 45

Going ahead to step 3:
If we divide 184 by 45, we get 4 and a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 180 from 184, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 45

Moving on to step 4:
45 goes into 47 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 41.0
Subtracting 45 from 47 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 45

Moving on to step 5:
45 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 410.0
Subtracting 0 from 28 leaves us with 28.
Fetch the next digit (1) from the dividend, attach it to 28 and continue: 281 / 45

On to step 6:
281 divided by 45 is 6 with a remainder of 11.
Use 6 as the next digit of our solution. 
Result so far: 4106.0
Deduct 270 from 281 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
The number 45 fits into 110 2 times, leaving a remainder of 20.
The number 2 becomes the next digit in our result. 
Result so far: 4106.2
Subtract 90 from 110 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 4106.24
Subtracting 180 from 200 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 9:
When dividing 200 by 45, we get 4 with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 4106.244
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Our division results in 4106.244 with a remaining 0.002.
