We look at the division of 484480 by 51 
We're looking to find how many times 51 goes into 484480.

Moving on to step 1:
When dividing 4 by 51, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 51

Moving on to step 2:
The number 51 fits into 48 0 times, leaving a remainder of 48.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 48 to get 48.
Include the next digit (4) from the dividend after 48, then repeat: 484 / 51

Going ahead to step 3:
484 divided by 51 is 9 with a remainder of 25.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 459 from 484 and we're left with 25.
Bring next digit (4) of the dividend behind the 25 and repeat the process: 254 / 51

Advancing to step 4:
If we divide 254 by 51, we get 4 and a remainder of 50.
The next digit of our result is 4. 
Result so far: 94.0
Deduct 204 from 254 and we're left with 50.
Append the next digit (8) from the dividend to 50 and continue with: 508 / 51

Step 5:
The number 51 fits into 508 9 times, leaving a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 949.0
The remainder is 49 after subtracting 459 from 508.
Include the next digit (0) from the dividend after 49, then repeat: 490 / 51

Moving on to step 6:
51 goes into 490 9 times with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 9499.0
Subtract 459 from 490 to 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.

Moving on to step 7:
If we divide 310 by 51, we get 6 and a remainder of 4.
The next digit of our result is 6. 
Result so far: 9499.6
If we subtract 306 from 310, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
The number 51 fits into 40 0 times, leaving a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 9499.6
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.

Moving on to step 9:
The number 51 fits into 400 7 times, leaving a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 9499.607
If we subtract 357 from 400, we get 43.
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 10:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 9499.6078
Subtract 408 from 430 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 11:
When dividing 220 by 51, we get 4 with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 9499.60784
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 12:
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: 9499.607843
If we subtract 153 from 160, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 13:
51 goes into 70 1 times with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 9499.6078431
Subtract 51 from 70 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 14:
51 goes into 190 3 times with a remainder of 37.
The next digit of our result is 3. 
Result so far: 9499.60784313
If we take 153 away from 190, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

After the division, we end up with 9499.60784313 and a remainder of 3.7e-08.
