65510286 ÷ 666 
Our goal is to divide 65510286 by 666.

Let's proceed to step 1:
666 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 666

Let's proceed to step 2:
666 can be fit into 65 0 times, resulting in a remainder of 65.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Bring next digit (5) of the dividend behind the 65 and repeat the process: 655 / 666

Let's proceed to step 3:
When dividing 655 by 666, we get 0 with a remainder of 655.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 655 leaves us with 655.
Include the next digit (1) from the dividend after 655, then repeat: 6551 / 666

Moving on to step 4:
If we divide 6551 by 666, we get 9 and a remainder of 557.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 5994 from 6551, we get 557.
Take the next digit (0) from the dividend and append it to 557, then repeat: 5570 / 666

Advancing to step 5:
When dividing 5570 by 666, we get 8 with a remainder of 242.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Subtracting 5328 from 5570 leaves us with 242.
Take the next digit (2) from the dividend and append it to 242, then repeat: 2422 / 666

Moving on to step 6:
The number 666 fits into 2422 3 times, leaving a remainder of 424.
Record the quotient 3 as the next digit in the result. 
Result so far: 983.0
Subtracting 1998 from 2422 leaves us with 424.
Fetch the next digit (8) from the dividend, attach it to 424 and continue: 4248 / 666

Step 7:
If we divide 4248 by 666, we get 6 and a remainder of 252.
Write down 6 as next digit of the result. 
Result so far: 9836.0
Subtracting 3996 from 4248 leaves us with 252.
Append the next digit (6) from the dividend to 252 and continue with: 2526 / 666

Let's proceed to step 8:
666 can be fit into 2526 3 times, resulting in a remainder of 528.
Write down 3 as next digit of the result. 
Result so far: 98363.0
Subtract 1998 from 2526 to get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 9:
When dividing 5280 by 666, we get 7 with a remainder of 618.
The next digit of our result is 7. 
Result so far: 98363.7
Subtracting 4662 from 5280 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Advancing to step 10:
666 can be fit into 6180 9 times, resulting in a remainder of 186.
Write down 9 as next digit of the result. 
Result so far: 98363.79
Subtracting 5994 from 6180 leaves us with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Let's proceed to step 11:
If we divide 1860 by 666, we get 2 and a remainder of 528.
The next digit of our result is 2. 
Result so far: 98363.792
If we subtract 1332 from 1860, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Advancing to step 12:
5280 divided by 666 is 7 with a remainder of 618.
Use 7 as the next digit of our solution. 
Result so far: 98363.7927
If we take 4662 away from 5280, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 13:
When dividing 6180 by 666, we get 9 with a remainder of 186.
The next digit of our result is 9. 
Result so far: 98363.79279
Deduct 5994 from 6180 and we're left with 186.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

Advancing to step 14:
If we divide 1860 by 666, we get 2 and a remainder of 528.
Put 2 as the next digit of the answer. 
Result so far: 98363.792792
Subtracting 1332 from 1860 leaves us with 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Let's proceed to step 15:
The number 666 fits into 5280 7 times, leaving a remainder of 618.
The number 7 becomes the next digit in our result. 
Result so far: 98363.7927927
If we take 4662 away from 5280, we end up with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Going ahead to step 16:
When dividing 6180 by 666, we get 9 with a remainder of 186.
The next digit of our result is 9. 
Result so far: 98363.79279279
The remainder is 186 after subtracting 5994 from 6180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1860, and continue the process.

The quotient of the division is 98363.79279279, and the remainder is 1.86e-07.
