352469 ÷ 20 
Our goal is to divide 352469 by 20.

Going ahead to step 1:
If we divide 3 by 20, we get 0 and a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 20

Advancing to step 2:
If we divide 35 by 20, we get 1 and a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 20 from 35 to get 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 20

Let's proceed to step 3:
20 can be fit into 152 7 times, resulting in a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
Subtract 140 from 152 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 20

Advancing to step 4:
124 divided by 20 is 6 with a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
If we take 120 away from 124, we end up with 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 20

Moving on to step 5:
46 divided by 20 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 1762.0
The remainder is 6 after subtracting 40 from 46.
Take the next digit (9) from the dividend and append it to 6, then repeat: 69 / 20

Advancing to step 6:
20 goes into 69 3 times with a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 17623.0
If we take 60 away from 69, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 17623.4
If we subtract 80 from 90, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 17623.45
Subtracting 100 from 100 leaves us 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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 17623.45
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 10:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17623.45
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.

After the division, we end up with 17623.45 and a remainder of 0.0.
