We look at the division of 454094 by 45 
The aim is to understand the frequency of 45 in 454094.

Going ahead to step 1:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 45

Step 2:
If we divide 45 by 45, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 45 away from 45, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 45

Let's proceed to step 3:
45 can be fit into 4 0 times, resulting in a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 45

Let's proceed to step 4:
45 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 100.0
Deduct 0 from 40 and we're left with 40.
Include the next digit (9) from the dividend after 40, then repeat: 409 / 45

On to step 5:
45 goes into 409 9 times with a remainder of 4.
Use 9 as the next digit of our solution. 
Result so far: 1009.0
If we take 405 away from 409, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

Going ahead to step 6:
44 divided by 45 is 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 10090.0
If we subtract 0 from 44, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
45 can be fit into 440 9 times, resulting in a remainder of 35.
Write down 9 as next digit of the result. 
Result so far: 10090.9
Deduct 405 from 440 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 8:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 10090.97
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
45 can be fit into 350 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 10090.977
Subtract 315 from 350 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final outcome is 10090.977, with a leftover of 0.0035.
