414974 divided by 21 
Let's see how many times 21 fits into 414974.

Advancing to step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 21

Going ahead to step 2:
41 divided by 21 is 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 21 from 41, we get 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 21

Advancing to step 3:
21 can be fit into 204 9 times, resulting in a remainder of 15.
The next digit of our result is 9. 
Result so far: 19.0
If we take 189 away from 204, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 21

Let's proceed to step 4:
If we divide 159 by 21, we get 7 and a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 197.0
The remainder is 12 after subtracting 147 from 159.
Bring next digit (7) of the dividend behind the 12 and repeat the process: 127 / 21

Let's proceed to step 5:
21 can be fit into 127 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 1976.0
If we take 126 away from 127, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 21

Moving on to step 6:
14 divided by 21 is 0 with a remainder of 14.
Write down 0 as next digit of the result. 
Result so far: 19760.0
Subtracting 0 from 14 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
140 divided by 21 is 6 with a remainder of 14.
Put 6 as the next digit of the answer. 
Result so far: 19760.6
Subtracting 126 from 140 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 8:
The number 21 fits into 140 6 times, leaving a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 19760.66
Subtract 126 from 140 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

The final result is 19760.66 with a remainder of 0.014.
