2555 divided by 4 
The aim is to understand the frequency of 4 in 2555.

On to step 1:
4 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 4

Going ahead to step 2:
If we divide 25 by 4, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 24 from 25 to get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 4

Step 3:
4 can be fit into 15 3 times, resulting in a remainder of 3.
The next digit of our result is 3. 
Result so far: 63.0
Subtracting 12 from 15 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 4

Let's proceed to step 4:
When dividing 35 by 4, we get 8 with a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 638.0
Deduct 32 from 35 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 5:
4 can be fit into 30 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 638.7
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.

Moving on to step 6:
20 divided by 4 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 638.75
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.

Let's proceed to step 7:
0 divided by 4 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 638.75
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.

Step 8:
0 divided by 4 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 638.75
If we subtract 0 from 0, 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.

Our division results in 638.75 with a remaining 0.0.
