66880220 divided by 671 
Our goal is to divide 66880220 by 671.

On to step 1:
671 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 671

Advancing to step 2:
When dividing 66 by 671, we get 0 with a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 671

Advancing to step 3:
If we divide 668 by 671, we get 0 and a remainder of 668.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 668 after subtracting 0 from 668.
Append the next digit (8) from the dividend to 668 and continue with: 6688 / 671

Going ahead to step 4:
When dividing 6688 by 671, we get 9 with a remainder of 649.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 6039 from 6688 leaves us with 649.
Grab the next digit (0) from the dividend, add it to 649, then carry on: 6490 / 671

On to step 5:
671 can be fit into 6490 9 times, resulting in a remainder of 451.
The next digit of our result is 9. 
Result so far: 99.0
If we take 6039 away from 6490, we end up with 451.
Grab the next digit (2) from the dividend, add it to 451, then carry on: 4512 / 671

On to step 6:
When dividing 4512 by 671, we get 6 with a remainder of 486.
Write down 6 as next digit of the result. 
Result so far: 996.0
Subtracting 4026 from 4512 leaves us with 486.
Fetch the next digit (2) from the dividend, attach it to 486 and continue: 4862 / 671

Going ahead to step 7:
The number 671 fits into 4862 7 times, leaving a remainder of 165.
Use 7 as the next digit of our solution. 
Result so far: 9967.0
Subtracting 4697 from 4862 leaves us with 165.
Grab the next digit (0) from the dividend, add it to 165, then carry on: 1650 / 671

Advancing to step 8:
671 goes into 1650 2 times with a remainder of 308.
Record the quotient 2 as the next digit in the result. 
Result so far: 99672.0
If we subtract 1342 from 1650, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

On to step 9:
When dividing 3080 by 671, we get 4 with a remainder of 396.
The next digit of our result is 4. 
Result so far: 99672.4
Subtract 2684 from 3080 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
If we divide 3960 by 671, we get 5 and a remainder of 605.
Use 5 as the next digit of our solution. 
Result so far: 99672.45
Subtract 3355 from 3960 to get 605.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6050, and continue the process.

Going ahead to step 11:
6050 divided by 671 is 9 with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 99672.459
The remainder is 11 after subtracting 6039 from 6050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 12:
If we divide 110 by 671, we get 0 and a remainder of 110.
Use 0 as the next digit of our solution. 
Result so far: 99672.459
The remainder is 110 after subtracting 0 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

Let's proceed to step 13:
671 goes into 1100 1 times with a remainder of 429.
Record the quotient 1 as the next digit in the result. 
Result so far: 99672.45901
Subtract 671 from 1100 to get 429.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

Going ahead to step 14:
671 can be fit into 4290 6 times, resulting in a remainder of 264.
Put 6 as the next digit of the answer. 
Result so far: 99672.459016
Subtract 4026 from 4290 to get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 15:
671 can be fit into 2640 3 times, resulting in a remainder of 627.
The next digit of our result is 3. 
Result so far: 99672.4590163
The remainder is 627 after subtracting 2013 from 2640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6270, and continue the process.

Moving on to step 16:
If we divide 6270 by 671, we get 9 and a remainder of 231.
The number 9 becomes the next digit in our result. 
Result so far: 99672.45901639
If we take 6039 away from 6270, we end up with 231.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2310, and continue the process.

The final outcome is 99672.45901639, with a leftover of 2.31e-07.
