We're dividing 352291 by 20 
We want to figure out the number of times 352291 can be divided by 20.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Fetch the next digit (5) from the dividend, attach it to 3 and continue: 35 / 20

Step 2:
20 goes into 35 1 times with a remainder of 15.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 20 away from 35, we end up with 15.
Append the next digit (2) from the dividend to 15 and continue with: 152 / 20

Let's proceed to step 3:
When dividing 152 by 20, we get 7 with a remainder of 12.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 140 from 152, we get 12.
Fetch the next digit (2) from the dividend, attach it to 12 and continue: 122 / 20

Moving on to step 4:
If we divide 122 by 20, we get 6 and a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 176.0
Deduct 120 from 122 and we're left with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 20

Step 5:
If we divide 29 by 20, we get 1 and a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 1761.0
If we take 20 away from 29, we end up with 9.
Include the next digit (1) from the dividend after 9, then repeat: 91 / 20

Advancing to step 6:
When dividing 91 by 20, we get 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 17614.0
Subtracting 80 from 91 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 7:
20 goes into 110 5 times with a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 17614.5
Subtracting 100 from 110 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.

Step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 17614.55
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.

Our division results in 17614.55 with a remaining 0.0.
