We look at the division of 159709 by 20 
Our goal is to divide 159709 by 20.

Step 1:
If we divide 1 by 20, we get 0 and a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Step 2:
When dividing 15 by 20, we get 0 with a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Append the next digit (9) from the dividend to 15 and continue with: 159 / 20

Let's proceed to step 3:
When dividing 159 by 20, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 140 from 159 and we're left with 19.
Include the next digit (7) from the dividend after 19, then repeat: 197 / 20

Moving on to step 4:
If we divide 197 by 20, we get 9 and a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
Subtract 180 from 197 to get 17.
Fetch the next digit (0) from the dividend, attach it to 17 and continue: 170 / 20

Let's proceed to step 5:
When dividing 170 by 20, we get 8 with a remainder of 10.
The number 8 becomes the next digit in our result. 
Result so far: 798.0
Subtract 160 from 170 to get 10.
Take the next digit (9) from the dividend and append it to 10, then repeat: 109 / 20

Step 6:
20 goes into 109 5 times with a remainder of 9.
The number 5 becomes the next digit in our result. 
Result so far: 7985.0
The remainder is 9 after subtracting 100 from 109.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 7:
20 goes into 90 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 7985.4
Subtracting 80 from 90 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.

Let's proceed to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7985.45
If we take 100 away from 100, 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.

Moving on to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7985.45
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.

Let's proceed to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7985.45
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 7985.45 with a remainder of 0.0.
