We look at the division of 454045 by 49 
The aim is to understand the frequency of 49 in 454045.

Step 1:
4 divided by 49 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 49

Advancing to step 2:
When dividing 45 by 49, we get 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 45 to get 45.
Append the next digit (4) from the dividend to 45 and continue with: 454 / 49

Moving on to step 3:
The number 49 fits into 454 9 times, leaving a remainder of 13.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 13 after subtracting 441 from 454.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 49

Let's proceed to step 4:
49 goes into 130 2 times with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 98 from 130 leaves us with 32.
Append the next digit (4) from the dividend to 32 and continue with: 324 / 49

On to step 5:
324 divided by 49 is 6 with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 926.0
If we take 294 away from 324, we end up with 30.
Grab the next digit (5) from the dividend, add it to 30, then carry on: 305 / 49

On to step 6:
49 can be fit into 305 6 times, resulting in a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 9266.0
Deduct 294 from 305 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 7:
When dividing 110 by 49, we get 2 with a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 9266.2
If we subtract 98 from 110, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 8:
120 divided by 49 is 2 with a remainder of 22.
Use 2 as the next digit of our solution. 
Result so far: 9266.22
The remainder is 22 after subtracting 98 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 9266.22 with a remainder of 0.022.
