123420 ÷ 48 
The aim is to understand the frequency of 48 in 123420.

Moving on to step 1:
If we divide 1 by 48, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 48

On to step 2:
48 goes into 12 0 times with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Append the next digit (3) from the dividend to 12 and continue with: 123 / 48

On to step 3:
123 divided by 48 is 2 with a remainder of 27.
The next digit of our result is 2. 
Result so far: 2.0
If we take 96 away from 123, we end up with 27.
Include the next digit (4) from the dividend after 27, then repeat: 274 / 48

Step 4:
The number 48 fits into 274 5 times, leaving a remainder of 34.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
If we take 240 away from 274, we end up with 34.
Include the next digit (2) from the dividend after 34, then repeat: 342 / 48

Advancing to step 5:
If we divide 342 by 48, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 257.0
Subtract 336 from 342 to get 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 48

On to step 6:
The number 48 fits into 60 1 times, leaving a remainder of 12.
The number 1 becomes the next digit in our result. 
Result so far: 2571.0
The remainder is 12 after subtracting 48 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 7:
48 goes into 120 2 times with a remainder of 24.
The next digit of our result is 2. 
Result so far: 2571.2
Deduct 96 from 120 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.

Let's proceed to step 8:
If we divide 240 by 48, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 2571.25
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.

Step 9:
The number 48 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 2571.25
Subtracting 0 from 0 leaves us 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.

Let's proceed to step 10:
48 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2571.25
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.

Our division results in 2571.25 with a remaining 0.0.
