We're dividing 50810203 by 489 
Let's see how many times 489 fits into 50810203.

Advancing to step 1:
5 divided by 489 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 489

Moving on to step 2:
If we divide 50 by 489, we get 0 and a remainder of 50.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 50 and we're left with 50.
Fetch the next digit (8) from the dividend, attach it to 50 and continue: 508 / 489

Advancing to step 3:
When dividing 508 by 489, we get 1 with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 489 from 508 leaves us with 19.
Bring next digit (1) of the dividend behind the 19 and repeat the process: 191 / 489

Moving on to step 4:
If we divide 191 by 489, we get 0 and a remainder of 191.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Deduct 0 from 191 and we're left with 191.
Take the next digit (0) from the dividend and append it to 191, then repeat: 1910 / 489

Going ahead to step 5:
489 goes into 1910 3 times with a remainder of 443.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Subtracting 1467 from 1910 leaves us with 443.
Fetch the next digit (2) from the dividend, attach it to 443 and continue: 4432 / 489

On to step 6:
If we divide 4432 by 489, we get 9 and a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
Subtracting 4401 from 4432 leaves us with 31.
Fetch the next digit (0) from the dividend, attach it to 31 and continue: 310 / 489

Advancing to step 7:
489 goes into 310 0 times with a remainder of 310.
Record the quotient 0 as the next digit in the result. 
Result so far: 10390.0
If we subtract 0 from 310, we get 310.
Bring next digit (3) of the dividend behind the 310 and repeat the process: 3103 / 489

On to step 8:
489 can be fit into 3103 6 times, resulting in a remainder of 169.
Record the quotient 6 as the next digit in the result. 
Result so far: 103906.0
If we subtract 2934 from 3103, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Going ahead to step 9:
1690 divided by 489 is 3 with a remainder of 223.
The number 3 becomes the next digit in our result. 
Result so far: 103906.3
Subtract 1467 from 1690 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Going ahead to step 10:
489 can be fit into 2230 4 times, resulting in a remainder of 274.
Write down 4 as next digit of the result. 
Result so far: 103906.34
If we subtract 1956 from 2230, we get 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Advancing to step 11:
489 can be fit into 2740 5 times, resulting in a remainder of 295.
The next digit of our result is 5. 
Result so far: 103906.345
The remainder is 295 after subtracting 2445 from 2740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2950, and continue the process.

On to step 12:
489 goes into 2950 6 times with a remainder of 16.
The next digit of our result is 6. 
Result so far: 103906.3456
Deduct 2934 from 2950 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
489 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 103906.3456
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
When dividing 1600 by 489, we get 3 with a remainder of 133.
The next digit of our result is 3. 
Result so far: 103906.345603
Subtract 1467 from 1600 to get 133.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1330, and continue the process.

Step 15:
489 goes into 1330 2 times with a remainder of 352.
The number 2 becomes the next digit in our result. 
Result so far: 103906.3456032
If we take 978 away from 1330, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Step 16:
3520 divided by 489 is 7 with a remainder of 97.
Use 7 as the next digit of our solution. 
Result so far: 103906.34560327
Subtract 3423 from 3520 to get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

The final outcome is 103906.34560327, with a leftover of 9.7e-08.
