Let's divide 235930 by 20
We want to figure out the number of times 235930 can be divided by 20.

Advancing to step 1:
20 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 20

On to step 2:
23 divided by 20 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 20 from 23 and we're left with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 20

Moving on to step 3:
20 can be fit into 35 1 times, resulting in a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we take 20 away from 35, we end up with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 20

On to step 4:
The number 20 fits into 159 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 117.0
Subtracting 140 from 159 leaves us with 19.
Take the next digit (3) from the dividend and append it to 19, then repeat: 193 / 20

Moving on to step 5:
If we divide 193 by 20, we get 9 and a remainder of 13.
Record the quotient 9 as the next digit in the result. 
Result so far: 1179.0
Subtracting 180 from 193 leaves us with 13.
Grab the next digit (0) from the dividend, add it to 13, then carry on: 130 / 20

Moving on to step 6:
20 goes into 130 6 times with a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 11796.0
The remainder is 10 after subtracting 120 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 11796.5
If we subtract 100 from 100, 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.

On to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 11796.5
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 9:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 11796.5
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.

The final result is 11796.5 with a remainder of 0.0.
