318392 ÷ 20 
We want to divide 318392 by 20.

On to step 1:
20 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 20

Going ahead to step 2:
20 can be fit into 31 1 times, resulting in a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 20 from 31 to get 11.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 20

On to step 3:
118 divided by 20 is 5 with a remainder of 18.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we take 100 away from 118, we end up with 18.
Append the next digit (3) from the dividend to 18 and continue with: 183 / 20

Step 4:
If we divide 183 by 20, we get 9 and a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Deduct 180 from 183 and we're left with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 20

Moving on to step 5:
The number 20 fits into 39 1 times, leaving a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1591.0
If we subtract 20 from 39, we get 19.
Fetch the next digit (2) from the dividend, attach it to 19 and continue: 192 / 20

Going ahead to step 6:
20 can be fit into 192 9 times, resulting in a remainder of 12.
Write down 9 as next digit of the result. 
Result so far: 15919.0
Subtracting 180 from 192 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
If we divide 120 by 20, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 15919.6
Subtracting 120 from 120 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.

Let's proceed to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15919.6
Subtracting 0 from 0 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.

Let's proceed to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 15919.6
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.

Our division results in 15919.6 with a remaining 0.0.
