We look at the division of 480268 by 51 
We want to figure out the number of times 480268 can be divided by 51.

Step 1:
51 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (8) of the dividend behind the 4 and repeat the process: 48 / 51

On to step 2:
48 divided by 51 is 0 with a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 48 leaves us with 48.
Append the next digit (0) from the dividend to 48 and continue with: 480 / 51

Step 3:
If we divide 480 by 51, we get 9 and a remainder of 21.
The next digit of our result is 9. 
Result so far: 9.0
If we subtract 459 from 480, we get 21.
Bring next digit (2) of the dividend behind the 21 and repeat the process: 212 / 51

Going ahead to step 4:
51 goes into 212 4 times with a remainder of 8.
The next digit of our result is 4. 
Result so far: 94.0
If we take 204 away from 212, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 51

On to step 5:
When dividing 86 by 51, we get 1 with a remainder of 35.
The number 1 becomes the next digit in our result. 
Result so far: 941.0
Deduct 51 from 86 and we're left with 35.
Include the next digit (8) from the dividend after 35, then repeat: 358 / 51

Going ahead to step 6:
The number 51 fits into 358 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 9417.0
Subtracting 357 from 358 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
51 can be fit into 10 0 times, resulting in a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 9417.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 51, we get 1 with a remainder of 49.
Record the quotient 1 as the next digit in the result. 
Result so far: 9417.01
If we subtract 51 from 100, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 9:
51 can be fit into 490 9 times, resulting in a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9417.019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Going ahead to step 10:
51 goes into 310 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 9417.0196
If we take 306 away from 310, 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.

Let's proceed to step 11:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 9417.0196
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 12:
When dividing 400 by 51, we get 7 with a remainder of 43.
The next digit of our result is 7. 
Result so far: 9417.019607
The remainder is 43 after subtracting 357 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Advancing to step 13:
The number 51 fits into 430 8 times, leaving a remainder of 22.
Write down 8 as next digit of the result. 
Result so far: 9417.0196078
If we take 408 away from 430, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 14:
51 can be fit into 220 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 9417.01960784
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.

The final result is 9417.01960784 with a remainder of 1.6e-08.
