We look at the division of 300438 by 48 
The aim is to understand the frequency of 48 in 300438.

On to step 1:
The number 48 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 48

Going ahead to step 2:
48 can be fit into 30 0 times, resulting in a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Include the next digit (0) from the dividend after 30, then repeat: 300 / 48

Going ahead to step 3:
48 can be fit into 300 6 times, resulting in a remainder of 12.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 288 away from 300, we end up with 12.
Append the next digit (4) from the dividend to 12 and continue with: 124 / 48

Let's proceed to step 4:
48 goes into 124 2 times with a remainder of 28.
The number 2 becomes the next digit in our result. 
Result so far: 62.0
The remainder is 28 after subtracting 96 from 124.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 48

Going ahead to step 5:
283 divided by 48 is 5 with a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 625.0
Subtract 240 from 283 to get 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 48

Going ahead to step 6:
If we divide 438 by 48, we get 9 and a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 6259.0
Subtracting 432 from 438 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.

Step 7:
When dividing 60 by 48, we get 1 with a remainder of 12.
The next digit of our result is 1. 
Result so far: 6259.1
Subtract 48 from 60 to 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.

Let's proceed to step 8:
48 goes into 120 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 6259.12
If we subtract 96 from 120, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 9:
If we divide 240 by 48, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 6259.125
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.

Advancing to step 10:
When dividing 0 by 48, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 6259.125
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.

Going ahead to step 11:
0 divided by 48 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6259.125
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.

The quotient of the division is 6259.125, and the remainder is 0.0.
