949543 divided by 21 
Our goal is to divide 949543 by 21.

Moving on to step 1:
9 divided by 21 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 21

Advancing to step 2:
When dividing 94 by 21, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 84 from 94 leaves us with 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 21

Step 3:
When dividing 109 by 21, we get 5 with a remainder of 4.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 105 away from 109, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 21

Moving on to step 4:
45 divided by 21 is 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 452.0
Subtracting 42 from 45 leaves us with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 21

On to step 5:
21 goes into 34 1 times with a remainder of 13.
The next digit of our result is 1. 
Result so far: 4521.0
The remainder is 13 after subtracting 21 from 34.
Grab the next digit (3) from the dividend, add it to 13, then carry on: 133 / 21

Step 6:
133 divided by 21 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 45216.0
Deduct 126 from 133 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 7:
21 can be fit into 70 3 times, resulting in a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 45216.3
If we take 63 away from 70, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 8:
70 divided by 21 is 3 with a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 45216.33
The remainder is 7 after subtracting 63 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

After the division, we end up with 45216.33 and a remainder of 0.007.
