We divide 128048 by 45
The aim is to understand the frequency of 45 in 128048.

Advancing to step 1:
When dividing 1 by 45, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 45

Step 2:
45 can be fit into 12 0 times, resulting in a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 45

Advancing to step 3:
When dividing 128 by 45, we get 2 with a remainder of 38.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 90 from 128, we get 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 45

Step 4:
The number 45 fits into 380 8 times, leaving a remainder of 20.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 360 from 380 and we're left with 20.
Append the next digit (4) from the dividend to 20 and continue with: 204 / 45

On to step 5:
If we divide 204 by 45, we get 4 and a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 284.0
If we subtract 180 from 204, we get 24.
Bring next digit (8) of the dividend behind the 24 and repeat the process: 248 / 45

Let's proceed to step 6:
45 goes into 248 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 2845.0
Subtract 225 from 248 to get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
The number 45 fits into 230 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 2845.5
If we subtract 225 from 230, 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.

Moving on to step 8:
When dividing 50 by 45, we get 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 2845.51
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.

Let's proceed to step 9:
50 divided by 45 is 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 2845.511
Deduct 45 from 50 and we're left 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.

The final result is 2845.511 with a remainder of 0.0005.
