We look at the division of 416360 by 21 
We're looking to find how many times 21 goes into 416360.

Step 1:
If we divide 4 by 21, we get 0 and a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 21

On to step 2:
When dividing 41 by 21, we get 1 with a remainder of 20.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 21 from 41 to get 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 21

Let's proceed to step 3:
206 divided by 21 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 19.0
If we take 189 away from 206, we end up with 17.
Include the next digit (3) from the dividend after 17, then repeat: 173 / 21

Step 4:
When dividing 173 by 21, we get 8 with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 198.0
Subtract 168 from 173 to get 5.
Take the next digit (6) from the dividend and append it to 5, then repeat: 56 / 21

Going ahead to step 5:
21 can be fit into 56 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1982.0
Deduct 42 from 56 and we're left with 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 21

Going ahead to step 6:
21 can be fit into 140 6 times, resulting in a remainder of 14.
Write down 6 as next digit of the result. 
Result so far: 19826.0
Deduct 126 from 140 and we're left 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.

Step 7:
When dividing 140 by 21, we get 6 with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 19826.6
Deduct 126 from 140 and we're left 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.

Going ahead to step 8:
140 divided by 21 is 6 with a remainder of 14.
The number 6 becomes the next digit in our result. 
Result so far: 19826.66
If we take 126 away from 140, we end up 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.

Our division results in 19826.66 with a remaining 0.014.
