66510459 divided by 772 
Let's see how many times 772 fits into 66510459.

Advancing to step 1:
If we divide 6 by 772, we get 0 and a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 772

Step 2:
772 can be fit into 66 0 times, resulting in a remainder of 66.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 66, we get 66.
Append the next digit (5) from the dividend to 66 and continue with: 665 / 772

Going ahead to step 3:
772 can be fit into 665 0 times, resulting in a remainder of 665.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 665 and we're left with 665.
Include the next digit (1) from the dividend after 665, then repeat: 6651 / 772

Moving on to step 4:
772 goes into 6651 8 times with a remainder of 475.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 6176 from 6651, we get 475.
Take the next digit (0) from the dividend and append it to 475, then repeat: 4750 / 772

Going ahead to step 5:
772 can be fit into 4750 6 times, resulting in a remainder of 118.
Use 6 as the next digit of our solution. 
Result so far: 86.0
Subtract 4632 from 4750 to get 118.
Include the next digit (4) from the dividend after 118, then repeat: 1184 / 772

On to step 6:
1184 divided by 772 is 1 with a remainder of 412.
Write down 1 as next digit of the result. 
Result so far: 861.0
If we subtract 772 from 1184, we get 412.
Bring next digit (5) of the dividend behind the 412 and repeat the process: 4125 / 772

Advancing to step 7:
772 can be fit into 4125 5 times, resulting in a remainder of 265.
The next digit of our result is 5. 
Result so far: 8615.0
Subtracting 3860 from 4125 leaves us with 265.
Take the next digit (9) from the dividend and append it to 265, then repeat: 2659 / 772

On to step 8:
2659 divided by 772 is 3 with a remainder of 343.
The number 3 becomes the next digit in our result. 
Result so far: 86153.0
Subtracting 2316 from 2659 leaves us with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

On to step 9:
When dividing 3430 by 772, we get 4 with a remainder of 342.
The number 4 becomes the next digit in our result. 
Result so far: 86153.4
Deduct 3088 from 3430 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
3420 divided by 772 is 4 with a remainder of 332.
The number 4 becomes the next digit in our result. 
Result so far: 86153.44
Subtracting 3088 from 3420 leaves us with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

The final result is 86153.44 with a remainder of 0.332.
