We look at the division of 500872 by 48 
The aim is to understand the frequency of 48 in 500872.

Let's proceed to step 1:
5 divided by 48 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 48

On to step 2:
The number 48 fits into 50 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 48 from 50 to get 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 48

Advancing to step 3:
48 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 48

Let's proceed to step 4:
If we divide 208 by 48, we get 4 and a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
If we subtract 192 from 208, we get 16.
Append the next digit (7) from the dividend to 16 and continue with: 167 / 48

Let's proceed to step 5:
The number 48 fits into 167 3 times, leaving a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 1043.0
Deduct 144 from 167 and we're left with 23.
Grab the next digit (2) from the dividend, add it to 23, then carry on: 232 / 48

Going ahead to step 6:
48 goes into 232 4 times with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 10434.0
Deduct 192 from 232 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 7:
48 can be fit into 400 8 times, resulting in a remainder of 16.
The next digit of our result is 8. 
Result so far: 10434.8
If we subtract 384 from 400, 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.

Let's proceed to step 8:
160 divided by 48 is 3 with a remainder of 16.
The number 3 becomes the next digit in our result. 
Result so far: 10434.83
Deduct 144 from 160 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.

Advancing to step 9:
160 divided by 48 is 3 with a remainder of 16.
Put 3 as the next digit of the answer. 
Result so far: 10434.833
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 10434.833, with a leftover of 0.0016.
