285394 ÷ 20 
We want to divide 285394 by 20.

Step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 20

Advancing to step 2:
If we divide 28 by 20, we get 1 and a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 8 after subtracting 20 from 28.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 20

Moving on to step 3:
The number 20 fits into 85 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 14.0
Subtract 80 from 85 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 20

On to step 4:
When dividing 53 by 20, we get 2 with a remainder of 13.
The next digit of our result is 2. 
Result so far: 142.0
Subtracting 40 from 53 leaves us with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 20

Step 5:
139 divided by 20 is 6 with a remainder of 19.
The number 6 becomes the next digit in our result. 
Result so far: 1426.0
Subtracting 120 from 139 leaves us with 19.
Grab the next digit (4) from the dividend, add it to 19, then carry on: 194 / 20

Going ahead to step 6:
If we divide 194 by 20, we get 9 and a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 14269.0
Subtracting 180 from 194 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 20 fits into 140 7 times, leaving a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 14269.7
If we take 140 away from 140, 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.

On to step 8:
20 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 14269.7
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.

On 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: 14269.7
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.

After the division, we end up with 14269.7 and a remainder of 0.0.
