949683 ÷ 21 
We want to divide 949683 by 21.

Advancing to step 1:
21 goes into 9 0 times with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 21

Step 2:
21 can be fit into 94 4 times, resulting in a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 10 after subtracting 84 from 94.
Grab the next digit (9) from the dividend, add it to 10, then carry on: 109 / 21

Advancing to step 3:
21 goes into 109 5 times with a remainder of 4.
The next digit of our result is 5. 
Result so far: 45.0
Subtract 105 from 109 to get 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 21

Step 4:
The number 21 fits into 46 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 452.0
Subtract 42 from 46 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 21

On to step 5:
21 goes into 48 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4522.0
If we subtract 42 from 48, we get 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 21

Going ahead to step 6:
63 divided by 21 is 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 45223.0
The remainder is 0 after subtracting 63 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
21 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 45223.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
21 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45223.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 45223.0 and a remainder of 0.0.
