We look at the division of 580576 by 48 
The aim is to understand the frequency of 48 in 580576.

Going ahead to step 1:
48 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 48

Let's proceed to step 2:
58 divided by 48 is 1 with a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 48 from 58 and we're left with 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 48

Moving on to step 3:
48 can be fit into 100 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 12.0
The remainder is 4 after subtracting 96 from 100.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 48

Advancing to step 4:
45 divided by 48 is 0 with a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 120.0
If we subtract 0 from 45, we get 45.
Bring next digit (7) of the dividend behind the 45 and repeat the process: 457 / 48

Advancing to step 5:
The number 48 fits into 457 9 times, leaving a remainder of 25.
The number 9 becomes the next digit in our result. 
Result so far: 1209.0
Subtract 432 from 457 to get 25.
Bring next digit (6) of the dividend behind the 25 and repeat the process: 256 / 48

Moving on to step 6:
If we divide 256 by 48, we get 5 and a remainder of 16.
Use 5 as the next digit of our solution. 
Result so far: 12095.0
The remainder is 16 after subtracting 240 from 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
48 can be fit into 160 3 times, resulting in a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 12095.3
Subtracting 144 from 160 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 8:
48 goes into 160 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 12095.33
The remainder is 16 after subtracting 144 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 12095.33, with a leftover of 0.016.
