65616217 ÷ 216 
We want to figure out the number of times 65616217 can be divided by 216.

Let's proceed to step 1:
If we divide 6 by 216, we get 0 and 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.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 216

Let's proceed to step 2:
The number 216 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 65 and we're left with 65.
Take the next digit (6) from the dividend and append it to 65, then repeat: 656 / 216

Step 3:
656 divided by 216 is 3 with a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 648 from 656, we get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 216

On to step 4:
216 goes into 81 0 times with a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 81 after subtracting 0 from 81.
Grab the next digit (6) from the dividend, add it to 81, then carry on: 816 / 216

On to step 5:
When dividing 816 by 216, we get 3 with a remainder of 168.
Write down 3 as next digit of the result. 
Result so far: 303.0
The remainder is 168 after subtracting 648 from 816.
Take the next digit (2) from the dividend and append it to 168, then repeat: 1682 / 216

Advancing to step 6:
1682 divided by 216 is 7 with a remainder of 170.
Put 7 as the next digit of the answer. 
Result so far: 3037.0
Deduct 1512 from 1682 and we're left with 170.
Include the next digit (1) from the dividend after 170, then repeat: 1701 / 216

Moving on to step 7:
When dividing 1701 by 216, we get 7 with a remainder of 189.
Use 7 as the next digit of our solution. 
Result so far: 30377.0
The remainder is 189 after subtracting 1512 from 1701.
Bring next digit (7) of the dividend behind the 189 and repeat the process: 1897 / 216

Going ahead to step 8:
When dividing 1897 by 216, we get 8 with a remainder of 169.
The next digit of our result is 8. 
Result so far: 303778.0
If we subtract 1728 from 1897, we get 169.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1690, and continue the process.

Let's proceed to step 9:
216 goes into 1690 7 times with a remainder of 178.
Write down 7 as next digit of the result. 
Result so far: 303778.7
Subtracting 1512 from 1690 leaves us with 178.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1780, and continue the process.

Going ahead to step 10:
If we divide 1780 by 216, we get 8 and a remainder of 52.
Put 8 as the next digit of the answer. 
Result so far: 303778.78
Subtract 1728 from 1780 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 11:
520 divided by 216 is 2 with a remainder of 88.
The number 2 becomes the next digit in our result. 
Result so far: 303778.782
The remainder is 88 after subtracting 432 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Let's proceed to step 12:
When dividing 880 by 216, we get 4 with a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 303778.7824
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 13:
216 goes into 160 0 times with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 303778.7824
If we subtract 0 from 160, we get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Let's proceed to step 14:
216 goes into 1600 7 times with a remainder of 88.
Use 7 as the next digit of our solution. 
Result so far: 303778.782407
The remainder is 88 after subtracting 1512 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 15:
216 can be fit into 880 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 303778.7824074
The remainder is 16 after subtracting 864 from 880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 16:
The number 216 fits into 160 0 times, leaving a remainder of 160.
Use 0 as the next digit of our solution. 
Result so far: 303778.7824074
Subtracting 0 from 160 leaves us with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final result is 303778.7824074 with a remainder of 1.6e-07.
