Let's divide 949578 by 21
We want to divide 949578 by 21.

Step 1:
9 divided by 21 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 21

Let's proceed to step 2:
94 divided by 21 is 4 with a remainder of 10.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 84 from 94 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 21

On to step 3:
The number 21 fits into 109 5 times, leaving a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we subtract 105 from 109, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

On to step 4:
21 can be fit into 45 2 times, resulting in a remainder of 3.
The next digit of our result is 2. 
Result so far: 452.0
The remainder is 3 after subtracting 42 from 45.
Fetch the next digit (7) from the dividend, attach it to 3 and continue: 37 / 21

Step 5:
21 goes into 37 1 times with a remainder of 16.
The next digit of our result is 1. 
Result so far: 4521.0
If we subtract 21 from 37, we get 16.
Take the next digit (8) from the dividend and append it to 16, then repeat: 168 / 21

Let's proceed to step 6:
21 can be fit into 168 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 45218.0
If we take 168 away from 168, 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.

Let's proceed to step 7:
The number 21 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 45218.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 21 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 45218.0
Subtract 0 from 0 to get 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 45218.0 and a remainder of 0.0.
