Let's divide 486576 by 51
We're looking to find how many times 51 goes into 486576.

On to step 1:
51 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 51

Going ahead to step 2:
48 divided by 51 is 0 with a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 51

Let's proceed to step 3:
51 can be fit into 486 9 times, resulting in a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 459 from 486 leaves us with 27.
Append the next digit (5) from the dividend to 27 and continue with: 275 / 51

On to step 4:
51 can be fit into 275 5 times, resulting in a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 95.0
The remainder is 20 after subtracting 255 from 275.
Grab the next digit (7) from the dividend, add it to 20, then carry on: 207 / 51

Going ahead to step 5:
If we divide 207 by 51, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 954.0
Subtract 204 from 207 to get 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 51

Let's proceed to step 6:
The number 51 fits into 36 0 times, leaving a remainder of 36.
Put 0 as the next digit of the answer. 
Result so far: 9540.0
Deduct 0 from 36 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 7:
360 divided by 51 is 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 9540.7
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
51 can be fit into 30 0 times, resulting in a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 9540.7
Subtract 0 from 30 to get 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 9:
If we divide 300 by 51, we get 5 and a remainder of 45.
The number 5 becomes the next digit in our result. 
Result so far: 9540.705
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.

On to step 10:
When dividing 450 by 51, we get 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 9540.7058
The remainder is 42 after subtracting 408 from 450.
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 11:
The number 51 fits into 420 8 times, leaving a remainder of 12.
The next digit of our result is 8. 
Result so far: 9540.70588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 9540.70588 and a remainder of 1.2e-05.
