470911 divided by 21 
Let's see how many times 21 fits into 470911.

Step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 21

Advancing to step 2:
21 goes into 47 2 times with a remainder of 5.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 5 after subtracting 42 from 47.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 21

Going ahead to step 3:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 22.0
Subtracting 42 from 50 leaves us with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 21

Let's proceed to step 4:
89 divided by 21 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 224.0
The remainder is 5 after subtracting 84 from 89.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 21

On to step 5:
51 divided by 21 is 2 with a remainder of 9.
Put 2 as the next digit of the answer. 
Result so far: 2242.0
The remainder is 9 after subtracting 42 from 51.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 21

Moving on to step 6:
When dividing 91 by 21, we get 4 with a remainder of 7.
The next digit of our result is 4. 
Result so far: 22424.0
If we take 84 away from 91, 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.

On to step 7:
21 goes into 70 3 times with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 22424.3
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 8:
If we divide 70 by 21, we get 3 and a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 22424.33
Subtracting 63 from 70 leaves us 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.

In conclusion, the division gives 22424.33 with a balance of 0.007.
