165044 ÷ 45 
The aim is to understand the frequency of 45 in 165044.

Step 1:
1 divided by 45 is 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 45

Moving on to step 2:
45 goes into 16 0 times with a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Take the next digit (5) from the dividend and append it to 16, then repeat: 165 / 45

On to step 3:
When dividing 165 by 45, we get 3 with a remainder of 30.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 135 from 165 and we're left with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 45

Going ahead to step 4:
300 divided by 45 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 36.0
Subtract 270 from 300 to get 30.
Include the next digit (4) from the dividend after 30, then repeat: 304 / 45

Moving on to step 5:
304 divided by 45 is 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 366.0
The remainder is 34 after subtracting 270 from 304.
Append the next digit (4) from the dividend to 34 and continue with: 344 / 45

Moving on to step 6:
45 can be fit into 344 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 3667.0
Subtract 315 from 344 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 7:
290 divided by 45 is 6 with a remainder of 20.
The next digit of our result is 6. 
Result so far: 3667.6
If we take 270 away from 290, we end up 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.

Moving on to step 8:
45 goes into 200 4 times with a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 3667.64
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.

Moving on to step 9:
If we divide 200 by 45, we get 4 and a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 3667.644
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.

The final outcome is 3667.644, with a leftover of 0.002.
