Let's divide 386158 by 20
We're looking to find how many times 20 goes into 386158.

On to step 1:
3 divided by 20 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 20

On to step 2:
When dividing 38 by 20, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtract 20 from 38 to get 18.
Take the next digit (6) from the dividend and append it to 18, then repeat: 186 / 20

Step 3:
When dividing 186 by 20, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
The remainder is 6 after subtracting 180 from 186.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 20

Moving on to step 4:
When dividing 61 by 20, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 193.0
The remainder is 1 after subtracting 60 from 61.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Let's proceed to step 5:
20 goes into 15 0 times with a remainder of 15.
The next digit of our result is 0. 
Result so far: 1930.0
Deduct 0 from 15 and we're left with 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 20

Advancing to step 6:
158 divided by 20 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 19307.0
Deduct 140 from 158 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 7:
If we divide 180 by 20, we get 9 and a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 19307.9
The remainder is 0 after subtracting 180 from 180.
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 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 19307.9
Subtract 0 from 0 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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 19307.9
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 quotient of the division is 19307.9, and the remainder is 0.0.
