We look at the division of 725448 by 48 
The aim is to understand the frequency of 48 in 725448.

Let's proceed to step 1:
48 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 48

On to step 2:
48 goes into 72 1 times with a remainder of 24.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 48 from 72 to get 24.
Fetch the next digit (5) from the dividend, attach it to 24 and continue: 245 / 48

On to step 3:
When dividing 245 by 48, we get 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 15.0
Subtracting 240 from 245 leaves us with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 48

Step 4:
When dividing 54 by 48, we get 1 with a remainder of 6.
The next digit of our result is 1. 
Result so far: 151.0
Subtracting 48 from 54 leaves us with 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 48

On to step 5:
When dividing 64 by 48, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 1511.0
The remainder is 16 after subtracting 48 from 64.
Grab the next digit (8) from the dividend, add it to 16, then carry on: 168 / 48

Advancing to step 6:
When dividing 168 by 48, we get 3 with a remainder of 24.
Use 3 as the next digit of our solution. 
Result so far: 15113.0
Deduct 144 from 168 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
The number 48 fits into 240 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 15113.5
If we take 240 away from 240, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
If we divide 0 by 48, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15113.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
0 divided by 48 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15113.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 15113.5, and the remainder is 0.0.
