We divide 374483 by 20
Let's see how many times 20 fits into 374483.

Moving on to step 1:
When dividing 3 by 20, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 20

Step 2:
20 can be fit into 37 1 times, resulting in a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we take 20 away from 37, we end up with 17.
Take the next digit (4) from the dividend and append it to 17, then repeat: 174 / 20

Going ahead to step 3:
174 divided by 20 is 8 with a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtracting 160 from 174 leaves us with 14.
Include the next digit (4) from the dividend after 14, then repeat: 144 / 20

Advancing to step 4:
144 divided by 20 is 7 with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 187.0
If we subtract 140 from 144, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 20

Moving on to step 5:
If we divide 48 by 20, we get 2 and a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 1872.0
Subtracting 40 from 48 leaves us with 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 20

Let's proceed to step 6:
When dividing 83 by 20, we get 4 with a remainder of 3.
The next digit of our result is 4. 
Result so far: 18724.0
If we subtract 80 from 83, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 18724.1
Deduct 20 from 30 and we're left 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 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 18724.15
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.

Let's proceed to step 9:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 18724.15
Subtract 0 from 0 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.

Step 10:
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: 18724.15
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.

The final result is 18724.15 with a remainder of 0.0.
