51300821 ÷ 764 
We want to divide 51300821 by 764.

On to step 1:
764 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 764

Going ahead to step 2:
764 can be fit into 51 0 times, resulting in a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Take the next digit (3) from the dividend and append it to 51, then repeat: 513 / 764

On to step 3:
764 can be fit into 513 0 times, resulting in a remainder of 513.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 513 leaves us with 513.
Take the next digit (0) from the dividend and append it to 513, then repeat: 5130 / 764

Moving on to step 4:
764 can be fit into 5130 6 times, resulting in a remainder of 546.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Deduct 4584 from 5130 and we're left with 546.
Append the next digit (0) from the dividend to 546 and continue with: 5460 / 764

Moving on to step 5:
764 can be fit into 5460 7 times, resulting in a remainder of 112.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Subtracting 5348 from 5460 leaves us with 112.
Append the next digit (8) from the dividend to 112 and continue with: 1128 / 764

Going ahead to step 6:
The number 764 fits into 1128 1 times, leaving a remainder of 364.
The next digit of our result is 1. 
Result so far: 671.0
If we subtract 764 from 1128, we get 364.
Include the next digit (2) from the dividend after 364, then repeat: 3642 / 764

On to step 7:
The number 764 fits into 3642 4 times, leaving a remainder of 586.
Write down 4 as next digit of the result. 
Result so far: 6714.0
The remainder is 586 after subtracting 3056 from 3642.
Bring next digit (1) of the dividend behind the 586 and repeat the process: 5861 / 764

Let's proceed to step 8:
764 can be fit into 5861 7 times, resulting in a remainder of 513.
Use 7 as the next digit of our solution. 
Result so far: 67147.0
If we take 5348 away from 5861, we end up with 513.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5130, and continue the process.

Step 9:
5130 divided by 764 is 6 with a remainder of 546.
Put 6 as the next digit of the answer. 
Result so far: 67147.6
If we subtract 4584 from 5130, we get 546.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5460, and continue the process.

Let's proceed to step 10:
When dividing 5460 by 764, we get 7 with a remainder of 112.
Use 7 as the next digit of our solution. 
Result so far: 67147.67
Deduct 5348 from 5460 and we're left with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 11:
764 can be fit into 1120 1 times, resulting in a remainder of 356.
The number 1 becomes the next digit in our result. 
Result so far: 67147.671
If we take 764 away from 1120, we end up with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Moving on to step 12:
If we divide 3560 by 764, we get 4 and a remainder of 504.
Record the quotient 4 as the next digit in the result. 
Result so far: 67147.6714
If we subtract 3056 from 3560, we get 504.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Moving on to step 13:
764 goes into 5040 6 times with a remainder of 456.
The number 6 becomes the next digit in our result. 
Result so far: 67147.67146
Subtracting 4584 from 5040 leaves us with 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 14:
764 goes into 4560 5 times with a remainder of 740.
The next digit of our result is 5. 
Result so far: 67147.671465
Deduct 3820 from 4560 and we're left with 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7400, and continue the process.

On to step 15:
When dividing 7400 by 764, we get 9 with a remainder of 524.
Record the quotient 9 as the next digit in the result. 
Result so far: 67147.6714659
Subtract 6876 from 7400 to get 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Step 16:
When dividing 5240 by 764, we get 6 with a remainder of 656.
Record the quotient 6 as the next digit in the result. 
Result so far: 67147.67146596
The remainder is 656 after subtracting 4584 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

After the division, we end up with 67147.67146596 and a remainder of 6.56e-07.
