We're dividing 604673 by 21 
We're looking to find how many times 21 goes into 604673.

Moving on to step 1:
If we divide 6 by 21, we get 0 and a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (0) from the dividend and append it to 6, then repeat: 60 / 21

On to step 2:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 42 from 60 and we're left with 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 21

Going ahead to step 3:
21 goes into 184 8 times with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtracting 168 from 184 leaves us with 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 21

Moving on to step 4:
If we divide 166 by 21, we get 7 and a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 287.0
The remainder is 19 after subtracting 147 from 166.
Append the next digit (7) from the dividend to 19 and continue with: 197 / 21

Moving on to step 5:
The number 21 fits into 197 9 times, leaving a remainder of 8.
Write down 9 as next digit of the result. 
Result so far: 2879.0
If we take 189 away from 197, we end up with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 21

Advancing to step 6:
21 goes into 83 3 times with a remainder of 20.
Use 3 as the next digit of our solution. 
Result so far: 28793.0
If we take 63 away from 83, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 7:
The number 21 fits into 200 9 times, leaving a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 28793.9
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 8:
110 divided by 21 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 28793.95
Subtract 105 from 110 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 9:
21 goes into 50 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 28793.952
The remainder is 8 after subtracting 42 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 10:
21 goes into 80 3 times with a remainder of 17.
The next digit of our result is 3. 
Result so far: 28793.9523
Subtract 63 from 80 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 11:
If we divide 170 by 21, we get 8 and a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 28793.95238
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
When dividing 20 by 21, we get 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 28793.95238
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
21 goes into 200 9 times with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 28793.9523809
If we take 189 away from 200, we end up 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.

Moving on to step 14:
21 can be fit into 110 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 28793.95238095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 28793.95238095 with a remainder of 5e-09.
