411474 divided by 21 
We want to figure out the number of times 411474 can be divided by 21.

Going ahead to step 1:
21 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 21

Going ahead to step 2:
21 can be fit into 41 1 times, resulting in 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.
Bring next digit (1) of the dividend behind the 20 and repeat the process: 201 / 21

Let's proceed to step 3:
21 goes into 201 9 times with a remainder of 12.
The next digit of our result is 9. 
Result so far: 19.0
The remainder is 12 after subtracting 189 from 201.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 21

Advancing to step 4:
When dividing 124 by 21, we get 5 with a remainder of 19.
Write down 5 as next digit of the result. 
Result so far: 195.0
The remainder is 19 after subtracting 105 from 124.
Take the next digit (7) from the dividend and append it to 19, then repeat: 197 / 21

Moving on to step 5:
The number 21 fits into 197 9 times, leaving a remainder of 8.
The next digit of our result is 9. 
Result so far: 1959.0
If we subtract 189 from 197, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 21

On to step 6:
If we divide 84 by 21, we get 4 and a remainder of 0.
The next digit of our result is 4. 
Result so far: 19594.0
Subtract 84 from 84 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.

Moving on to step 7:
If we divide 0 by 21, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19594.0
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.

Let's proceed 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: 19594.0
Deduct 0 from 0 and we're left 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.

The final result is 19594.0 with a remainder of 0.0.
