64663209 ÷ 217 
We want to figure out the number of times 64663209 can be divided by 217.

Let's proceed to step 1:
217 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 217

Going ahead to step 2:
The number 217 fits into 64 0 times, leaving a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 217

Advancing to step 3:
When dividing 646 by 217, we get 2 with a remainder of 212.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 212 after subtracting 434 from 646.
Fetch the next digit (6) from the dividend, attach it to 212 and continue: 2126 / 217

On to step 4:
217 can be fit into 2126 9 times, resulting in a remainder of 173.
Use 9 as the next digit of our solution. 
Result so far: 29.0
Subtract 1953 from 2126 to get 173.
Take the next digit (3) from the dividend and append it to 173, then repeat: 1733 / 217

Let's proceed to step 5:
The number 217 fits into 1733 7 times, leaving a remainder of 214.
Use 7 as the next digit of our solution. 
Result so far: 297.0
If we take 1519 away from 1733, we end up with 214.
Include the next digit (2) from the dividend after 214, then repeat: 2142 / 217

On to step 6:
217 goes into 2142 9 times with a remainder of 189.
Put 9 as the next digit of the answer. 
Result so far: 2979.0
If we take 1953 away from 2142, we end up with 189.
Append the next digit (0) from the dividend to 189 and continue with: 1890 / 217

Moving on to step 7:
217 goes into 1890 8 times with a remainder of 154.
The next digit of our result is 8. 
Result so far: 29798.0
If we subtract 1736 from 1890, we get 154.
Grab the next digit (9) from the dividend, add it to 154, then carry on: 1549 / 217

Step 8:
When dividing 1549 by 217, we get 7 with a remainder of 30.
The next digit of our result is 7. 
Result so far: 297987.0
Deduct 1519 from 1549 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
If we divide 300 by 217, we get 1 and a remainder of 83.
Write down 1 as next digit of the result. 
Result so far: 297987.1
Deduct 217 from 300 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Advancing to step 10:
217 can be fit into 830 3 times, resulting in a remainder of 179.
The next digit of our result is 3. 
Result so far: 297987.13
If we take 651 away from 830, we end up with 179.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1790, and continue the process.

On to step 11:
When dividing 1790 by 217, we get 8 with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 297987.138
Subtracting 1736 from 1790 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 12:
540 divided by 217 is 2 with a remainder of 106.
Record the quotient 2 as the next digit in the result. 
Result so far: 297987.1382
If we take 434 away from 540, we end up with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Moving on to step 13:
If we divide 1060 by 217, we get 4 and a remainder of 192.
The next digit of our result is 4. 
Result so far: 297987.13824
Subtract 868 from 1060 to get 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Going ahead to step 14:
217 goes into 1920 8 times with a remainder of 184.
The number 8 becomes the next digit in our result. 
Result so far: 297987.138248
The remainder is 184 after subtracting 1736 from 1920.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Going ahead to step 15:
When dividing 1840 by 217, we get 8 with a remainder of 104.
Put 8 as the next digit of the answer. 
Result so far: 297987.1382488
Subtracting 1736 from 1840 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

After the division, we end up with 297987.1382488 and a remainder of 1.04e-06.
