Let's divide 168449 by 45
The aim is to understand the frequency of 45 in 168449.

Step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 45

Let's proceed to step 2:
If we divide 16 by 45, we get 0 and a remainder of 16.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Append the next digit (8) from the dividend to 16 and continue with: 168 / 45

Going ahead to step 3:
168 divided by 45 is 3 with a remainder of 33.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 135 from 168 to get 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 45

On to step 4:
45 goes into 334 7 times with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 37.0
Subtracting 315 from 334 leaves us with 19.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 45

Advancing to step 5:
The number 45 fits into 194 4 times, leaving a remainder of 14.
The next digit of our result is 4. 
Result so far: 374.0
If we take 180 away from 194, we end up with 14.
Fetch the next digit (9) from the dividend, attach it to 14 and continue: 149 / 45

Advancing to step 6:
45 goes into 149 3 times with a remainder of 14.
The next digit of our result is 3. 
Result so far: 3743.0
If we subtract 135 from 149, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 7:
When dividing 140 by 45, we get 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 3743.3
If we subtract 135 from 140, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 8:
50 divided by 45 is 1 with a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 3743.31
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3743.311
Subtracting 45 from 50 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Our division results in 3743.311 with a remaining 0.0005.
