We divide 408093 by 45
The aim is to understand the frequency of 45 in 408093.

Moving on to step 1:
4 divided by 45 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 45

Step 2:
40 divided by 45 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Bring next digit (8) of the dividend behind the 40 and repeat the process: 408 / 45

Moving on to step 3:
When dividing 408 by 45, we get 9 with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 405 from 408 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 45

On to step 4:
The number 45 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 90.0
Deduct 0 from 30 and we're left with 30.
Fetch the next digit (9) from the dividend, attach it to 30 and continue: 309 / 45

Step 5:
45 can be fit into 309 6 times, resulting in a remainder of 39.
The number 6 becomes the next digit in our result. 
Result so far: 906.0
If we subtract 270 from 309, we get 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 45

Moving on to step 6:
45 can be fit into 393 8 times, resulting in a remainder of 33.
The number 8 becomes the next digit in our result. 
Result so far: 9068.0
If we take 360 away from 393, we end up with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 7:
45 can be fit into 330 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 9068.7
Subtract 315 from 330 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 8:
When dividing 150 by 45, we get 3 with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 9068.73
Deduct 135 from 150 and we're left with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 9:
45 goes into 150 3 times with a remainder of 15.
The next digit of our result is 3. 
Result so far: 9068.733
Subtract 135 from 150 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The quotient of the division is 9068.733, and the remainder is 0.0015.
