Let's divide 417538 by 20
We're looking to find how many times 20 goes into 417538.

Let's proceed to step 1:
4 divided by 20 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 20

Going ahead to step 2:
When dividing 41 by 20, we get 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we subtract 40 from 41, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 20

Let's proceed to step 3:
17 divided by 20 is 0 with a remainder of 17.
Put 0 as the next digit of the answer. 
Result so far: 20.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 20

Advancing to step 4:
If we divide 175 by 20, we get 8 and a remainder of 15.
Write down 8 as next digit of the result. 
Result so far: 208.0
The remainder is 15 after subtracting 160 from 175.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 20

Advancing to step 5:
When dividing 153 by 20, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 2087.0
Subtract 140 from 153 to get 13.
Bring next digit (8) of the dividend behind the 13 and repeat the process: 138 / 20

Let's proceed to step 6:
When dividing 138 by 20, we get 6 with a remainder of 18.
Use 6 as the next digit of our solution. 
Result so far: 20876.0
The remainder is 18 after subtracting 120 from 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
If we divide 180 by 20, we get 9 and a remainder of 0.
The next digit of our result is 9. 
Result so far: 20876.9
Subtract 180 from 180 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.

Going ahead to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20876.9
If we take 0 away from 0, we end up 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20876.9
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.

Our division results in 20876.9 with a remaining 0.0.
