21304004 ÷ 676 
Let's see how many times 676 fits into 21304004.

Going ahead to step 1:
When dividing 2 by 676, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 676

Going ahead to step 2:
The number 676 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Fetch the next digit (3) from the dividend, attach it to 21 and continue: 213 / 676

Let's proceed to step 3:
676 goes into 213 0 times with a remainder of 213.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Append the next digit (0) from the dividend to 213 and continue with: 2130 / 676

Let's proceed to step 4:
The number 676 fits into 2130 3 times, leaving a remainder of 102.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 2028 from 2130, we get 102.
Grab the next digit (4) from the dividend, add it to 102, then carry on: 1024 / 676

Advancing to step 5:
676 goes into 1024 1 times with a remainder of 348.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
The remainder is 348 after subtracting 676 from 1024.
Include the next digit (0) from the dividend after 348, then repeat: 3480 / 676

Step 6:
3480 divided by 676 is 5 with a remainder of 100.
Use 5 as the next digit of our solution. 
Result so far: 315.0
If we take 3380 away from 3480, we end up with 100.
Fetch the next digit (0) from the dividend, attach it to 100 and continue: 1000 / 676

Going ahead to step 7:
When dividing 1000 by 676, we get 1 with a remainder of 324.
The next digit of our result is 1. 
Result so far: 3151.0
Deduct 676 from 1000 and we're left with 324.
Bring next digit (4) of the dividend behind the 324 and repeat the process: 3244 / 676

Advancing to step 8:
When dividing 3244 by 676, we get 4 with a remainder of 540.
Record the quotient 4 as the next digit in the result. 
Result so far: 31514.0
Subtracting 2704 from 3244 leaves us with 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5400, and continue the process.

On to step 9:
5400 divided by 676 is 7 with a remainder of 668.
Put 7 as the next digit of the answer. 
Result so far: 31514.7
Subtracting 4732 from 5400 leaves us with 668.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6680, and continue the process.

On to step 10:
If we divide 6680 by 676, we get 9 and a remainder of 596.
Use 9 as the next digit of our solution. 
Result so far: 31514.79
Subtracting 6084 from 6680 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Moving on to step 11:
When dividing 5960 by 676, we get 8 with a remainder of 552.
The number 8 becomes the next digit in our result. 
Result so far: 31514.798
If we take 5408 away from 5960, we end up with 552.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5520, and continue the process.

On to step 12:
676 goes into 5520 8 times with a remainder of 112.
The next digit of our result is 8. 
Result so far: 31514.7988
Subtracting 5408 from 5520 leaves us with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 31514.7988 and a remainder of 0.00112.
