572728 ÷ 48 
The aim is to understand the frequency of 48 in 572728.

Going ahead to step 1:
When dividing 5 by 48, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 48

Going ahead to step 2:
57 divided by 48 is 1 with a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 48 from 57 to get 9.
Include the next digit (2) from the dividend after 9, then repeat: 92 / 48

Advancing to step 3:
92 divided by 48 is 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 48 from 92 and we're left with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 48

Going ahead to step 4:
447 divided by 48 is 9 with a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 119.0
Deduct 432 from 447 and we're left with 15.
Include the next digit (2) from the dividend after 15, then repeat: 152 / 48

Advancing to step 5:
152 divided by 48 is 3 with a remainder of 8.
Put 3 as the next digit of the answer. 
Result so far: 1193.0
If we subtract 144 from 152, we get 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 48

Moving on to step 6:
88 divided by 48 is 1 with a remainder of 40.
The number 1 becomes the next digit in our result. 
Result so far: 11931.0
The remainder is 40 after subtracting 48 from 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
If we divide 400 by 48, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 11931.8
Deduct 384 from 400 and we're left 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.

Going ahead to step 8:
If we divide 160 by 48, we get 3 and a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 11931.83
If we subtract 144 from 160, we get 16.
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 9:
48 goes into 160 3 times with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 11931.833
If we take 144 away from 160, we end up 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.

The final outcome is 11931.833, with a leftover of 0.0016.
