Let's divide 48923 by 4
The aim is to understand the frequency of 4 in 48923.

Step 1:
4 divided by 4 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 4 from 4, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 4

Going ahead to step 2:
8 divided by 4 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 8 from 8 leaves us with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 4

Advancing to step 3:
The number 4 fits into 9 2 times, leaving a remainder of 1.
The next digit of our result is 2. 
Result so far: 122.0
The remainder is 1 after subtracting 8 from 9.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 4

Advancing to step 4:
4 goes into 12 3 times with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 1223.0
If we subtract 12 from 12, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 4

Advancing to step 5:
4 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 12230.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 6:
4 can be fit into 30 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 12230.7
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 4, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12230.75
Subtracting 20 from 20 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.

On to step 8:
If we divide 0 by 4, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12230.75
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.

Advancing to step 9:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12230.75
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 final outcome is 12230.75, with a leftover of 0.0.
