We look at the division of 135351 by 48 
The aim is to understand the frequency of 48 in 135351.

On to step 1:
The number 48 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 48

Going ahead to step 2:
48 goes into 13 0 times with a remainder of 13.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (5) from the dividend after 13, then repeat: 135 / 48

Advancing to step 3:
135 divided by 48 is 2 with a remainder of 39.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 96 from 135 to get 39.
Bring next digit (3) of the dividend behind the 39 and repeat the process: 393 / 48

On to step 4:
If we divide 393 by 48, we get 8 and a remainder of 9.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
The remainder is 9 after subtracting 384 from 393.
Include the next digit (5) from the dividend after 9, then repeat: 95 / 48

Moving on to step 5:
95 divided by 48 is 1 with a remainder of 47.
Record the quotient 1 as the next digit in the result. 
Result so far: 281.0
Subtract 48 from 95 to get 47.
Include the next digit (1) from the dividend after 47, then repeat: 471 / 48

Moving on to step 6:
When dividing 471 by 48, we get 9 with a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 2819.0
Deduct 432 from 471 and we're left 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 7:
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: 2819.8
Subtract 384 from 390 to get 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 8:
The number 48 fits into 60 1 times, leaving a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 2819.81
If we subtract 48 from 60, we get 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 9:
48 can be fit into 120 2 times, resulting in a remainder of 24.
The next digit of our result is 2. 
Result so far: 2819.812
Subtracting 96 from 120 leaves us 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.

Moving on to step 10:
48 goes into 240 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 2819.8125
If we subtract 240 from 240, 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.

Moving on to step 11:
48 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2819.8125
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.

Advancing to step 12:
48 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 2819.8125
If we take 0 away from 0, 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.

Our division results in 2819.8125 with a remaining 0.0.
