We're dividing 354477 by 20 
Our goal is to divide 354477 by 20.

Advancing to step 1:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (5) from the dividend to 3 and continue with: 35 / 20

On to step 2:
When dividing 35 by 20, we get 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 15 after subtracting 20 from 35.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

On to step 3:
154 divided by 20 is 7 with a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 140 from 154, we get 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 20

Moving on to step 4:
20 goes into 144 7 times with a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 177.0
Subtracting 140 from 144 leaves us with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 20

Let's proceed to step 5:
When dividing 47 by 20, we get 2 with a remainder of 7.
The next digit of our result is 2. 
Result so far: 1772.0
If we subtract 40 from 47, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 20

Moving on to step 6:
20 can be fit into 77 3 times, resulting in a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 17723.0
If we subtract 60 from 77, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 17723.8
Subtracting 160 from 170 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.

Moving on to step 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17723.85
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.

Going ahead to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17723.85
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17723.85
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 quotient of the division is 17723.85, and the remainder is 0.0.
