Let's divide 16604 by 23
Our goal is to divide 16604 by 23.

Let's proceed to step 1:
23 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (6) from the dividend, attach it to 1 and continue: 16 / 23

On to step 2:
The number 23 fits into 16 0 times, leaving a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 16, we get 16.
Take the next digit (6) from the dividend and append it to 16, then repeat: 166 / 23

Going ahead to step 3:
23 goes into 166 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 7.0
If we take 161 away from 166, we end up with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 23

Moving on to step 4:
50 divided by 23 is 2 with a remainder of 4.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
If we take 46 away from 50, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 23

Moving on to step 5:
44 divided by 23 is 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 721.0
Subtract 23 from 44 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 6:
The number 23 fits into 210 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 721.9
If we take 207 away from 210, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
When dividing 30 by 23, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 721.91
The remainder is 7 after subtracting 23 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
23 can be fit into 70 3 times, resulting in a remainder of 1.
The next digit of our result is 3. 
Result so far: 721.913
The remainder is 1 after subtracting 69 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
10 divided by 23 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 721.913
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
If we divide 100 by 23, we get 4 and a remainder of 8.
The next digit of our result is 4. 
Result so far: 721.91304
Subtract 92 from 100 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 11:
23 goes into 80 3 times with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 721.913043
Subtracting 69 from 80 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 12:
If we divide 110 by 23, we get 4 and a remainder of 18.
The next digit of our result is 4. 
Result so far: 721.9130434
Deduct 92 from 110 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 13:
23 goes into 180 7 times with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 721.91304347
Subtract 161 from 180 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 721.91304347 and a remainder of 1.9e-08.
