We divide 418190 by 20
Our goal is to divide 418190 by 20.

On to step 1:
20 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 20

On to step 2:
20 goes into 41 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtracting 40 from 41 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 20

Going ahead to step 3:
When dividing 18 by 20, we get 0 with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
Deduct 0 from 18 and we're left with 18.
Grab the next digit (1) from the dividend, add it to 18, then carry on: 181 / 20

Let's proceed to step 4:
20 goes into 181 9 times with a remainder of 1.
The number 9 becomes the next digit in our result. 
Result so far: 209.0
Deduct 180 from 181 and we're left with 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

Going ahead to step 5:
When dividing 19 by 20, we get 0 with a remainder of 19.
Record the quotient 0 as the next digit in the result. 
Result so far: 2090.0
Subtract 0 from 19 to get 19.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 20

Moving on to step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 20909.0
If we take 180 away from 190, we end up 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.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 20909.5
Deduct 100 from 100 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.

Advancing to step 8:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20909.5
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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20909.5
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.

Our division results in 20909.5 with a remaining 0.0.
