We divide 49989 by 50
We're looking to find how many times 50 goes into 49989.

On to step 1:
4 divided by 50 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 50

Going ahead to step 2:
49 divided by 50 is 0 with a remainder of 49.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Append the next digit (9) from the dividend to 49 and continue with: 499 / 50

Moving on to step 3:
The number 50 fits into 499 9 times, leaving a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 450 from 499, we get 49.
Append the next digit (8) from the dividend to 49 and continue with: 498 / 50

On to step 4:
498 divided by 50 is 9 with a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 450 away from 498, we end up with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 50

Advancing to step 5:
The number 50 fits into 489 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 999.0
Subtracting 450 from 489 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 6:
390 divided by 50 is 7 with a remainder of 40.
Write down 7 as next digit of the result. 
Result so far: 999.7
Subtracting 350 from 390 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.

On to step 7:
400 divided by 50 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 999.78
Subtract 400 from 400 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.

On to step 8:
The number 50 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 999.78
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.

Going ahead to step 9:
50 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 999.78
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.

The quotient of the division is 999.78, and the remainder is 0.0.
