65669980 ÷ 653 
We want to divide 65669980 by 653.

Going ahead to step 1:
If we divide 6 by 653, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 653

Let's proceed to step 2:
The number 653 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 65 leaves us with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 653

Moving on to step 3:
653 goes into 656 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 653 away from 656, we end up with 3.
Bring next digit (6) of the dividend behind the 3 and repeat the process: 36 / 653

Step 4:
36 divided by 653 is 0 with a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Deduct 0 from 36 and we're left with 36.
Bring next digit (9) of the dividend behind the 36 and repeat the process: 369 / 653

Step 5:
653 can be fit into 369 0 times, resulting in a remainder of 369.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we subtract 0 from 369, we get 369.
Append the next digit (9) from the dividend to 369 and continue with: 3699 / 653

Advancing to step 6:
653 goes into 3699 5 times with a remainder of 434.
Put 5 as the next digit of the answer. 
Result so far: 1005.0
If we subtract 3265 from 3699, we get 434.
Include the next digit (8) from the dividend after 434, then repeat: 4348 / 653

On to step 7:
The number 653 fits into 4348 6 times, leaving a remainder of 430.
The next digit of our result is 6. 
Result so far: 10056.0
Deduct 3918 from 4348 and we're left with 430.
Include the next digit (0) from the dividend after 430, then repeat: 4300 / 653

Let's proceed to step 8:
The number 653 fits into 4300 6 times, leaving a remainder of 382.
The number 6 becomes the next digit in our result. 
Result so far: 100566.0
If we take 3918 away from 4300, we end up with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Moving on to step 9:
653 goes into 3820 5 times with a remainder of 555.
The number 5 becomes the next digit in our result. 
Result so far: 100566.5
If we subtract 3265 from 3820, we get 555.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5550, and continue the process.

On to step 10:
The number 653 fits into 5550 8 times, leaving a remainder of 326.
Record the quotient 8 as the next digit in the result. 
Result so far: 100566.58
If we subtract 5224 from 5550, we get 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 11:
If we divide 3260 by 653, we get 4 and a remainder of 648.
The number 4 becomes the next digit in our result. 
Result so far: 100566.584
If we take 2612 away from 3260, we end up with 648.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6480, and continue the process.

Let's proceed to step 12:
If we divide 6480 by 653, we get 9 and a remainder of 603.
Use 9 as the next digit of our solution. 
Result so far: 100566.5849
The remainder is 603 after subtracting 5877 from 6480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6030, and continue the process.

Going ahead to step 13:
653 can be fit into 6030 9 times, resulting in a remainder of 153.
Write down 9 as next digit of the result. 
Result so far: 100566.58499
If we subtract 5877 from 6030, we get 153.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1530, and continue the process.

The final outcome is 100566.58499, with a leftover of 0.000153.
