We look at the division of 354542 by 20 
Our goal is to divide 354542 by 20.

On to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 20

Moving on to step 2:
35 divided by 20 is 1 with a remainder of 15.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 20 from 35 and we're left with 15.
Bring next digit (4) of the dividend behind the 15 and repeat the process: 154 / 20

On to step 3:
The number 20 fits into 154 7 times, leaving a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 140 from 154 leaves us with 14.
Fetch the next digit (5) from the dividend, attach it to 14 and continue: 145 / 20

Let's proceed to step 4:
20 goes into 145 7 times with a remainder of 5.
The next digit of our result is 7. 
Result so far: 177.0
Deduct 140 from 145 and we're left with 5.
Append the next digit (4) from the dividend to 5 and continue with: 54 / 20

Advancing to step 5:
If we divide 54 by 20, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 1772.0
The remainder is 14 after subtracting 40 from 54.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 20

Advancing to step 6:
The number 20 fits into 142 7 times, leaving a remainder of 2.
The next digit of our result is 7. 
Result so far: 17727.0
The remainder is 2 after subtracting 140 from 142.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
The number 20 fits into 20 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 17727.1
If we take 20 away from 20, 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 17727.1
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.

Moving on to 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: 17727.1
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 17727.1 with a balance of 0.0.
