490575 divided by 51 
We're looking to find how many times 51 goes into 490575.

Let's proceed to step 1:
The number 51 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 51

Going ahead to step 2:
51 goes into 49 0 times with a remainder of 49.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 49 leaves us with 49.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 51

Going ahead to step 3:
If we divide 490 by 51, we get 9 and a remainder of 31.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 459 from 490 and we're left with 31.
Grab the next digit (5) from the dividend, add it to 31, then carry on: 315 / 51

Let's proceed to step 4:
The number 51 fits into 315 6 times, leaving a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Deduct 306 from 315 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 51

Going ahead to step 5:
The number 51 fits into 97 1 times, leaving a remainder of 46.
The number 1 becomes the next digit in our result. 
Result so far: 961.0
Subtract 51 from 97 to get 46.
Append the next digit (5) from the dividend to 46 and continue with: 465 / 51

Let's proceed to step 6:
465 divided by 51 is 9 with a remainder of 6.
The next digit of our result is 9. 
Result so far: 9619.0
Subtracting 459 from 465 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
51 can be fit into 60 1 times, resulting in a remainder of 9.
The next digit of our result is 1. 
Result so far: 9619.1
If we take 51 away from 60, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 8:
When dividing 90 by 51, we get 1 with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 9619.11
If we subtract 51 from 90, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The quotient of the division is 9619.11, and the remainder is 0.039.
