We look at the division of 417410 by 20 
We're looking to find how many times 20 goes into 417410.

Let's proceed to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 20

Let's proceed to step 2:
When dividing 41 by 20, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 40 away from 41, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 20

Let's proceed to step 3:
If we divide 17 by 20, we get 0 and a remainder of 17.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 17, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 20

Advancing to step 4:
174 divided by 20 is 8 with a remainder of 14.
The next digit of our result is 8. 
Result so far: 208.0
The remainder is 14 after subtracting 160 from 174.
Take the next digit (1) from the dividend and append it to 14, then repeat: 141 / 20

Step 5:
The number 20 fits into 141 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 2087.0
If we subtract 140 from 141, we get 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 20

Moving on to step 6:
20 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 20870.0
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
If we divide 100 by 20, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20870.5
Subtracting 100 from 100 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.

Advancing to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 20870.5
If we subtract 0 from 0, we 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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20870.5
The remainder is 0 after subtracting 0 from 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 outcome is 20870.5, with a leftover of 0.0.
