318236 ÷ 20 
Our goal is to divide 318236 by 20.

Let's proceed to step 1:
The number 20 fits into 3 0 times, leaving a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 20

Going ahead to step 2:
The number 20 fits into 31 1 times, leaving a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 20 from 31, we get 11.
Fetch the next digit (8) from the dividend, attach it to 11 and continue: 118 / 20

Let's proceed to step 3:
The number 20 fits into 118 5 times, leaving a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 100 from 118 leaves us with 18.
Grab the next digit (2) from the dividend, add it to 18, then carry on: 182 / 20

Going ahead to step 4:
20 can be fit into 182 9 times, resulting in a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 159.0
If we subtract 180 from 182, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 20

Going ahead to step 5:
The number 20 fits into 23 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1591.0
Deduct 20 from 23 and we're left with 3.
Take the next digit (6) from the dividend and append it to 3, then repeat: 36 / 20

Moving on to step 6:
20 goes into 36 1 times with a remainder of 16.
The number 1 becomes the next digit in our result. 
Result so far: 15911.0
If we take 20 away from 36, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 7:
20 goes into 160 8 times with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 15911.8
Subtracting 160 from 160 leaves us 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.

Step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 15911.8
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 15911.8
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.

The final result is 15911.8 with a remainder of 0.0.
