4864 ÷ 90 
We want to divide 4864 by 90.

Let's proceed to step 1:
When dividing 4 by 90, we get 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 90

Step 2:
90 goes into 48 0 times with a remainder of 48.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Append the next digit (6) from the dividend to 48 and continue with: 486 / 90

Going ahead to step 3:
When dividing 486 by 90, we get 5 with a remainder of 36.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Deduct 450 from 486 and we're left with 36.
Include the next digit (4) from the dividend after 36, then repeat: 364 / 90

Step 4:
When dividing 364 by 90, we get 4 with a remainder of 4.
Put 4 as the next digit of the answer. 
Result so far: 54.0
Deduct 360 from 364 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 5:
The number 90 fits into 40 0 times, leaving a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 54.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 6:
400 divided by 90 is 4 with a remainder of 40.
Use 4 as the next digit of our solution. 
Result so far: 54.04
Subtract 360 from 400 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
400 divided by 90 is 4 with a remainder of 40.
The next digit of our result is 4. 
Result so far: 54.044
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 54.044 with a remainder of 0.004.
