We divide 16880639 by 668
Let's see how many times 668 fits into 16880639.

Advancing to step 1:
When dividing 1 by 668, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 668

Step 2:
The number 668 fits into 16 0 times, leaving a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Bring next digit (8) of the dividend behind the 16 and repeat the process: 168 / 668

Let's proceed to step 3:
168 divided by 668 is 0 with a remainder of 168.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 168, we end up with 168.
Grab the next digit (8) from the dividend, add it to 168, then carry on: 1688 / 668

Let's proceed to step 4:
1688 divided by 668 is 2 with a remainder of 352.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Deduct 1336 from 1688 and we're left with 352.
Fetch the next digit (0) from the dividend, attach it to 352 and continue: 3520 / 668

Moving on to step 5:
668 goes into 3520 5 times with a remainder of 180.
The next digit of our result is 5. 
Result so far: 25.0
Subtracting 3340 from 3520 leaves us with 180.
Append the next digit (6) from the dividend to 180 and continue with: 1806 / 668

Going ahead to step 6:
If we divide 1806 by 668, we get 2 and a remainder of 470.
The next digit of our result is 2. 
Result so far: 252.0
If we take 1336 away from 1806, we end up with 470.
Include the next digit (3) from the dividend after 470, then repeat: 4703 / 668

Step 7:
If we divide 4703 by 668, we get 7 and a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 2527.0
If we take 4676 away from 4703, we end up with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 668

Step 8:
279 divided by 668 is 0 with a remainder of 279.
Write down 0 as next digit of the result. 
Result so far: 25270.0
If we subtract 0 from 279, we get 279.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2790, and continue the process.

On to step 9:
668 can be fit into 2790 4 times, resulting in a remainder of 118.
Use 4 as the next digit of our solution. 
Result so far: 25270.4
Subtracting 2672 from 2790 leaves us with 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

On to step 10:
668 can be fit into 1180 1 times, resulting in a remainder of 512.
The number 1 becomes the next digit in our result. 
Result so far: 25270.41
If we subtract 668 from 1180, we get 512.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Step 11:
668 can be fit into 5120 7 times, resulting in a remainder of 444.
Record the quotient 7 as the next digit in the result. 
Result so far: 25270.417
Deduct 4676 from 5120 and we're left with 444.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4440, and continue the process.

On to step 12:
If we divide 4440 by 668, we get 6 and a remainder of 432.
Record the quotient 6 as the next digit in the result. 
Result so far: 25270.4176
If we take 4008 away from 4440, we end up with 432.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4320, and continue the process.

Step 13:
If we divide 4320 by 668, we get 6 and a remainder of 312.
Record the quotient 6 as the next digit in the result. 
Result so far: 25270.41766
If we subtract 4008 from 4320, we get 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

After the division, we end up with 25270.41766 and a remainder of 0.000312.
