366380 ÷ 20 
We're looking to find how many times 20 goes into 366380.

Going ahead to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 20

Going ahead to step 2:
If we divide 36 by 20, we get 1 and a remainder of 16.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 20 from 36, we get 16.
Include the next digit (6) from the dividend after 16, then repeat: 166 / 20

Step 3:
20 can be fit into 166 8 times, resulting in a remainder of 6.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 6 after subtracting 160 from 166.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Step 4:
If we divide 63 by 20, we get 3 and a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 183.0
If we take 60 away from 63, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 20

Let's proceed to step 5:
20 can be fit into 38 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1831.0
Subtracting 20 from 38 leaves us with 18.
Include the next digit (0) from the dividend after 18, then repeat: 180 / 20

Let's proceed to step 6:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 18319.0
If we subtract 180 from 180, 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.

Let's proceed to step 7:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 18319.0
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.

Let's proceed to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 18319.0
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.

In conclusion, the division gives 18319.0 with a balance of 0.0.
