8880721 ÷ 668 
Let's see how many times 668 fits into 8880721.

Advancing to step 1:
8 divided by 668 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 668

Let's proceed to step 2:
When dividing 88 by 668, we get 0 with a remainder of 88.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 88 after subtracting 0 from 88.
Take the next digit (8) from the dividend and append it to 88, then repeat: 888 / 668

Going ahead to step 3:
888 divided by 668 is 1 with a remainder of 220.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 668 from 888 leaves us with 220.
Take the next digit (0) from the dividend and append it to 220, then repeat: 2200 / 668

On to step 4:
668 can be fit into 2200 3 times, resulting in a remainder of 196.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 2004 away from 2200, we end up with 196.
Bring next digit (7) of the dividend behind the 196 and repeat the process: 1967 / 668

Let's proceed to step 5:
The number 668 fits into 1967 2 times, leaving a remainder of 631.
The number 2 becomes the next digit in our result. 
Result so far: 132.0
If we subtract 1336 from 1967, we get 631.
Bring next digit (2) of the dividend behind the 631 and repeat the process: 6312 / 668

Going ahead to step 6:
6312 divided by 668 is 9 with a remainder of 300.
Put 9 as the next digit of the answer. 
Result so far: 1329.0
Subtract 6012 from 6312 to get 300.
Append the next digit (1) from the dividend to 300 and continue with: 3001 / 668

On to step 7:
If we divide 3001 by 668, we get 4 and a remainder of 329.
The number 4 becomes the next digit in our result. 
Result so far: 13294.0
Subtracting 2672 from 3001 leaves us with 329.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3290, and continue the process.

Let's proceed to step 8:
668 can be fit into 3290 4 times, resulting in a remainder of 618.
The next digit of our result is 4. 
Result so far: 13294.4
The remainder is 618 after subtracting 2672 from 3290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 9:
6180 divided by 668 is 9 with a remainder of 168.
Put 9 as the next digit of the answer. 
Result so far: 13294.49
If we subtract 6012 from 6180, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Moving on to step 10:
If we divide 1680 by 668, we get 2 and a remainder of 344.
The next digit of our result is 2. 
Result so far: 13294.492
If we take 1336 away from 1680, we end up with 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Advancing to step 11:
668 can be fit into 3440 5 times, resulting in a remainder of 100.
Write down 5 as next digit of the result. 
Result so far: 13294.4925
Subtract 3340 from 3440 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 12:
1000 divided by 668 is 1 with a remainder of 332.
Record the quotient 1 as the next digit in the result. 
Result so far: 13294.49251
Deduct 668 from 1000 and we're left with 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Moving on to step 13:
When dividing 3320 by 668, we get 4 with a remainder of 648.
Record the quotient 4 as the next digit in the result. 
Result so far: 13294.492514
Subtracting 2672 from 3320 leaves us 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.

Step 14:
668 can be fit into 6480 9 times, resulting in a remainder of 468.
The next digit of our result is 9. 
Result so far: 13294.4925149
If we take 6012 away from 6480, we end up with 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 15:
If we divide 4680 by 668, we get 7 and a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 13294.49251497
If we subtract 4676 from 4680, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Our division results in 13294.49251497 with a remaining 4e-09.
