Let's divide 158240 by 20
Our goal is to divide 158240 by 20.

Advancing to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Moving on to step 2:
20 can be fit into 15 0 times, resulting in a remainder of 15.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 20

Step 3:
The number 20 fits into 158 7 times, leaving a remainder of 18.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 140 from 158, we get 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 20

Going ahead to step 4:
The number 20 fits into 182 9 times, leaving a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 79.0
Subtract 180 from 182 to get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 20

Step 5:
20 goes into 24 1 times with a remainder of 4.
The next digit of our result is 1. 
Result so far: 791.0
If we take 20 away from 24, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 20

Advancing to step 6:
If we divide 40 by 20, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 7912.0
Subtract 40 from 40 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.

On to step 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7912.0
The remainder is 0 after subtracting 0 from 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 8:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 7912.0
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.

Our division results in 7912.0 with a remaining 0.0.
