66600641 ÷ 217 
We want to divide 66600641 by 217.

Let's proceed to step 1:
6 divided by 217 is 0 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.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 217

On to step 2:
66 divided by 217 is 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Take the next digit (6) from the dividend and append it to 66, then repeat: 666 / 217

Going ahead to step 3:
When dividing 666 by 217, we get 3 with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we take 651 away from 666, we end up with 15.
Append the next digit (0) from the dividend to 15 and continue with: 150 / 217

Advancing to step 4:
If we divide 150 by 217, we get 0 and a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
Subtract 0 from 150 to get 150.
Append the next digit (0) from the dividend to 150 and continue with: 1500 / 217

Going ahead to step 5:
217 goes into 1500 6 times with a remainder of 198.
The number 6 becomes the next digit in our result. 
Result so far: 306.0
Subtracting 1302 from 1500 leaves us with 198.
Append the next digit (6) from the dividend to 198 and continue with: 1986 / 217

Step 6:
The number 217 fits into 1986 9 times, leaving a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 3069.0
Deduct 1953 from 1986 and we're left with 33.
Append the next digit (4) from the dividend to 33 and continue with: 334 / 217

Let's proceed to step 7:
217 goes into 334 1 times with a remainder of 117.
Record the quotient 1 as the next digit in the result. 
Result so far: 30691.0
Subtracting 217 from 334 leaves us with 117.
Bring next digit (1) of the dividend behind the 117 and repeat the process: 1171 / 217

Going ahead to step 8:
The number 217 fits into 1171 5 times, leaving a remainder of 86.
The number 5 becomes the next digit in our result. 
Result so far: 306915.0
Subtract 1085 from 1171 to get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Step 9:
If we divide 860 by 217, we get 3 and a remainder of 209.
The next digit of our result is 3. 
Result so far: 306915.3
Subtract 651 from 860 to get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 10:
2090 divided by 217 is 9 with a remainder of 137.
Put 9 as the next digit of the answer. 
Result so far: 306915.39
Deduct 1953 from 2090 and we're left with 137.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1370, and continue the process.

Moving on to step 11:
When dividing 1370 by 217, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 306915.396
Subtracting 1302 from 1370 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 12:
217 goes into 680 3 times with a remainder of 29.
Record the quotient 3 as the next digit in the result. 
Result so far: 306915.3963
The remainder is 29 after subtracting 651 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 13:
217 can be fit into 290 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 306915.39631
Subtract 217 from 290 to get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 14:
If we divide 730 by 217, we get 3 and a remainder of 79.
Write down 3 as next digit of the result. 
Result so far: 306915.396313
Subtracting 651 from 730 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 15:
217 goes into 790 3 times with a remainder of 139.
The number 3 becomes the next digit in our result. 
Result so far: 306915.3963133
Subtracting 651 from 790 leaves us with 139.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1390, and continue the process.

Our division results in 306915.3963133 with a remaining 1.39e-06.
