We're dividing 86385 by 20 
We want to figure out the number of times 86385 can be divided by 20.

Step 1:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 20

Going ahead to step 2:
20 goes into 86 4 times with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 80 from 86 leaves us with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 20

Step 3:
20 goes into 63 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 43.0
If we take 60 away from 63, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

Step 4:
20 goes into 38 1 times with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 431.0
Subtract 20 from 38 to get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 20

Advancing to step 5:
185 divided by 20 is 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 4319.0
Deduct 180 from 185 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 6:
50 divided by 20 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 4319.2
If we take 40 away from 50, we end up 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.

Moving on to step 7:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 4319.25
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.

Let's proceed 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: 4319.25
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.

Advancing 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: 4319.25
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.

After the division, we end up with 4319.25 and a remainder of 0.0.
