We look at the division of 490879 by 51 
We want to figure out the number of times 490879 can be divided by 51.

Moving on to step 1:
4 divided by 51 is 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 51

Step 2:
The number 51 fits into 49 0 times, leaving a remainder of 49.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Take the next digit (0) from the dividend and append it to 49, then repeat: 490 / 51

Step 3:
The number 51 fits into 490 9 times, leaving a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 459 from 490 and we're left with 31.
Bring next digit (8) of the dividend behind the 31 and repeat the process: 318 / 51

On to step 4:
51 goes into 318 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 96.0
Subtracting 306 from 318 leaves us with 12.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 51

Moving on to step 5:
The number 51 fits into 127 2 times, leaving a remainder of 25.
Put 2 as the next digit of the answer. 
Result so far: 962.0
Subtract 102 from 127 to get 25.
Grab the next digit (9) from the dividend, add it to 25, then carry on: 259 / 51

Advancing to step 6:
51 can be fit into 259 5 times, resulting in a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 9625.0
If we take 255 away from 259, we end up 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.

On to step 7:
If we divide 40 by 51, we get 0 and a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 9625.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 51, we get 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 9625.07
Subtracting 357 from 400 leaves us with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Let's proceed to step 9:
When dividing 430 by 51, we get 8 with a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 9625.078
The remainder is 22 after subtracting 408 from 430.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 10:
When dividing 220 by 51, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9625.0784
Deduct 204 from 220 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.

Let's proceed to step 11:
When dividing 160 by 51, we get 3 with a remainder of 7.
Record the quotient 3 as the next digit in the result. 
Result so far: 9625.07843
Subtracting 153 from 160 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 12:
The number 51 fits into 70 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9625.078431
The remainder is 19 after subtracting 51 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Moving on to step 13:
51 goes into 190 3 times with a remainder of 37.
Write down 3 as next digit of the result. 
Result so far: 9625.0784313
The remainder is 37 after subtracting 153 from 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 14:
When dividing 370 by 51, we get 7 with a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 9625.07843137
If we subtract 357 from 370, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

After the division, we end up with 9625.07843137 and a remainder of 1.3e-08.
