480168 divided by 51 
Our goal is to divide 480168 by 51.

Moving on to step 1:
If we divide 4 by 51, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 51

Advancing to step 2:
51 goes into 48 0 times with a remainder of 48.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (0) of the dividend behind the 48 and repeat the process: 480 / 51

Step 3:
51 goes into 480 9 times with a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we take 459 away from 480, we end up with 21.
Take the next digit (1) from the dividend and append it to 21, then repeat: 211 / 51

On to step 4:
51 goes into 211 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 94.0
Deduct 204 from 211 and we're left with 7.
Include the next digit (6) from the dividend after 7, then repeat: 76 / 51

Step 5:
76 divided by 51 is 1 with a remainder of 25.
Use 1 as the next digit of our solution. 
Result so far: 941.0
If we take 51 away from 76, we end up with 25.
Append the next digit (8) from the dividend to 25 and continue with: 258 / 51

Going ahead to step 6:
51 goes into 258 5 times with a remainder of 3.
The next digit of our result is 5. 
Result so far: 9415.0
Deduct 255 from 258 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
51 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9415.0
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 8:
51 can be fit into 300 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 9415.05
If we subtract 255 from 300, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 9:
450 divided by 51 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 9415.058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 10:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 9415.0588
Subtract 408 from 420 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 9415.0588, and the remainder is 0.00012.
