996149 divided by 45 
The aim is to understand the frequency of 45 in 996149.

Going ahead to step 1:
9 divided by 45 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (9) of the dividend behind the 9 and repeat the process: 99 / 45

Going ahead to step 2:
45 can be fit into 99 2 times, resulting in a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 90 from 99 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 45

Going ahead to step 3:
If we divide 96 by 45, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 22.0
The remainder is 6 after subtracting 90 from 96.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 45

On to step 4:
When dividing 61 by 45, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 221.0
Subtracting 45 from 61 leaves us with 16.
Append the next digit (4) from the dividend to 16 and continue with: 164 / 45

On to step 5:
45 goes into 164 3 times with a remainder of 29.
The next digit of our result is 3. 
Result so far: 2213.0
If we take 135 away from 164, we end up with 29.
Bring next digit (9) of the dividend behind the 29 and repeat the process: 299 / 45

Let's proceed to step 6:
If we divide 299 by 45, we get 6 and a remainder of 29.
Use 6 as the next digit of our solution. 
Result so far: 22136.0
If we take 270 away from 299, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 7:
45 goes into 290 6 times with a remainder of 20.
The next digit of our result is 6. 
Result so far: 22136.6
Subtracting 270 from 290 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.

Going ahead to step 8:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 22136.64
Deduct 180 from 200 and we're left 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:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 22136.644
If we take 180 away from 200, 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.

Our division results in 22136.644 with a remaining 0.002.
