51082812 divided by 660 
We want to figure out the number of times 51082812 can be divided by 660.

Step 1:
When dividing 5 by 660, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 660

Going ahead to step 2:
The number 660 fits into 51 0 times, leaving a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Append the next digit (0) from the dividend to 51 and continue with: 510 / 660

Going ahead to step 3:
660 can be fit into 510 0 times, resulting in a remainder of 510.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 510 after subtracting 0 from 510.
Fetch the next digit (8) from the dividend, attach it to 510 and continue: 5108 / 660

Moving on to step 4:
660 goes into 5108 7 times with a remainder of 488.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 4620 from 5108 and we're left with 488.
Include the next digit (2) from the dividend after 488, then repeat: 4882 / 660

Let's proceed to step 5:
If we divide 4882 by 660, we get 7 and a remainder of 262.
Put 7 as the next digit of the answer. 
Result so far: 77.0
Subtract 4620 from 4882 to get 262.
Include the next digit (8) from the dividend after 262, then repeat: 2628 / 660

Let's proceed to step 6:
The number 660 fits into 2628 3 times, leaving a remainder of 648.
Write down 3 as next digit of the result. 
Result so far: 773.0
Subtract 1980 from 2628 to get 648.
Grab the next digit (1) from the dividend, add it to 648, then carry on: 6481 / 660

Moving on to step 7:
The number 660 fits into 6481 9 times, leaving a remainder of 541.
Use 9 as the next digit of our solution. 
Result so far: 7739.0
Subtracting 5940 from 6481 leaves us with 541.
Bring next digit (2) of the dividend behind the 541 and repeat the process: 5412 / 660

On to step 8:
When dividing 5412 by 660, we get 8 with a remainder of 132.
Put 8 as the next digit of the answer. 
Result so far: 77398.0
If we take 5280 away from 5412, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Moving on to step 9:
1320 divided by 660 is 2 with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 77398.2
If we take 1320 away from 1320, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
If we divide 0 by 660, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 77398.2
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 11:
0 divided by 660 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 77398.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 77398.2, and the remainder is 0.0.
