We look at the division of 72864519 by 48 
The aim is to understand the frequency of 48 in 72864519.

Let's proceed to step 1:
When dividing 7 by 48, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 48

Going ahead to step 2:
When dividing 72 by 48, we get 1 with a remainder of 24.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 48 away from 72, we end up with 24.
Take the next digit (8) from the dividend and append it to 24, then repeat: 248 / 48

Step 3:
When dividing 248 by 48, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 15.0
Subtract 240 from 248 to get 8.
Grab the next digit (6) from the dividend, add it to 8, then carry on: 86 / 48

Going ahead to step 4:
If we divide 86 by 48, we get 1 and a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 151.0
The remainder is 38 after subtracting 48 from 86.
Grab the next digit (4) from the dividend, add it to 38, then carry on: 384 / 48

Moving on to step 5:
If we divide 384 by 48, we get 8 and a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 1518.0
If we take 384 away from 384, we end up with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 48

Going ahead to step 6:
48 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 15180.0
Subtract 0 from 5 to get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 48

Step 7:
48 goes into 51 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 151801.0
Deduct 48 from 51 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 48

Let's proceed to step 8:
48 can be fit into 39 0 times, resulting in a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 1518010.0
Subtracting 0 from 39 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 9:
If we divide 390 by 48, we get 8 and a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 1518010.8
Subtracting 384 from 390 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
If we divide 60 by 48, we get 1 and a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1518010.81
If we take 48 away from 60, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
The number 48 fits into 120 2 times, leaving a remainder of 24.
Put 2 as the next digit of the answer. 
Result so far: 1518010.812
The remainder is 24 after subtracting 96 from 120.
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 12:
48 goes into 240 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 1518010.8125
Subtract 240 from 240 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.

Going ahead to step 13:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1518010.8125
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 14:
If we divide 0 by 48, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1518010.8125
Deduct 0 from 0 and we're left 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.

Our division results in 1518010.8125 with a remaining 0.0.
