250336 ÷ 20 
Let's see how many times 20 fits into 250336.

Advancing to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 20

Moving on to step 2:
20 goes into 25 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 20 from 25 leaves us with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 20

Let's proceed to step 3:
20 goes into 50 2 times with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
Deduct 40 from 50 and we're left with 10.
Fetch the next digit (3) from the dividend, attach it to 10 and continue: 103 / 20

Moving on to step 4:
20 goes into 103 5 times with a remainder of 3.
Put 5 as the next digit of the answer. 
Result so far: 125.0
If we subtract 100 from 103, we get 3.
Fetch the next digit (3) from the dividend, attach it to 3 and continue: 33 / 20

Step 5:
33 divided by 20 is 1 with a remainder of 13.
The number 1 becomes the next digit in our result. 
Result so far: 1251.0
If we subtract 20 from 33, we get 13.
Take the next digit (6) from the dividend and append it to 13, then repeat: 136 / 20

Moving on to step 6:
When dividing 136 by 20, we get 6 with a remainder of 16.
The next digit of our result is 6. 
Result so far: 12516.0
If we subtract 120 from 136, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 7:
The number 20 fits into 160 8 times, leaving a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 12516.8
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.

On to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12516.8
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.

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: 12516.8
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.

In conclusion, the division gives 12516.8 with a balance of 0.0.
