65976498 ÷ 661 
We want to divide 65976498 by 661.

On to step 1:
When dividing 6 by 661, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 661

On to step 2:
When dividing 65 by 661, we get 0 with a remainder of 65.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Append the next digit (9) from the dividend to 65 and continue with: 659 / 661

Going ahead to step 3:
661 goes into 659 0 times with a remainder of 659.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 659 after subtracting 0 from 659.
Bring next digit (7) of the dividend behind the 659 and repeat the process: 6597 / 661

On to step 4:
The number 661 fits into 6597 9 times, leaving a remainder of 648.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 5949 from 6597 to get 648.
Include the next digit (6) from the dividend after 648, then repeat: 6486 / 661

On to step 5:
If we divide 6486 by 661, we get 9 and a remainder of 537.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we subtract 5949 from 6486, we get 537.
Take the next digit (4) from the dividend and append it to 537, then repeat: 5374 / 661

Step 6:
5374 divided by 661 is 8 with a remainder of 86.
Write down 8 as next digit of the result. 
Result so far: 998.0
If we take 5288 away from 5374, we end up with 86.
Append the next digit (9) from the dividend to 86 and continue with: 869 / 661

Step 7:
If we divide 869 by 661, we get 1 and a remainder of 208.
Put 1 as the next digit of the answer. 
Result so far: 9981.0
If we subtract 661 from 869, we get 208.
Take the next digit (8) from the dividend and append it to 208, then repeat: 2088 / 661

Going ahead to step 8:
If we divide 2088 by 661, we get 3 and a remainder of 105.
Write down 3 as next digit of the result. 
Result so far: 99813.0
Subtracting 1983 from 2088 leaves us with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Let's proceed to step 9:
When dividing 1050 by 661, we get 1 with a remainder of 389.
The next digit of our result is 1. 
Result so far: 99813.1
If we take 661 away from 1050, we end up with 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3890, and continue the process.

Moving on to step 10:
661 can be fit into 3890 5 times, resulting in a remainder of 585.
Put 5 as the next digit of the answer. 
Result so far: 99813.15
The remainder is 585 after subtracting 3305 from 3890.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5850, and continue the process.

Advancing to step 11:
When dividing 5850 by 661, we get 8 with a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 99813.158
Deduct 5288 from 5850 and we're left with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Advancing to step 12:
If we divide 5620 by 661, we get 8 and a remainder of 332.
The number 8 becomes the next digit in our result. 
Result so far: 99813.1588
Deduct 5288 from 5620 and we're left 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.

After the division, we end up with 99813.1588 and a remainder of 0.00332.
