49878 ÷ 90 
We want to divide 49878 by 90.

Let's proceed to step 1:
90 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 90

Let's proceed to step 2:
The number 90 fits into 49 0 times, leaving a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 90

Let's proceed to step 3:
The number 90 fits into 498 5 times, leaving a remainder of 48.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 450 from 498, we get 48.
Append the next digit (7) from the dividend to 48 and continue with: 487 / 90

Moving on to step 4:
487 divided by 90 is 5 with a remainder of 37.
Put 5 as the next digit of the answer. 
Result so far: 55.0
The remainder is 37 after subtracting 450 from 487.
Fetch the next digit (8) from the dividend, attach it to 37 and continue: 378 / 90

Step 5:
If we divide 378 by 90, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 554.0
Subtracting 360 from 378 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 6:
When dividing 180 by 90, we get 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 554.2
Deduct 180 from 180 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.

Moving on to step 7:
0 divided by 90 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 554.2
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.

Moving on to step 8:
90 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 554.2
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.

Our division results in 554.2 with a remaining 0.0.
