250914 ÷ 20 
Let's see how many times 20 fits into 250914.

Step 1:
When dividing 2 by 20, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Let's proceed to step 2:
If we divide 25 by 20, we get 1 and 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

Going ahead to step 3:
20 can be fit into 50 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 40 from 50, we get 10.
Bring next digit (9) of the dividend behind the 10 and repeat the process: 109 / 20

Step 4:
20 goes into 109 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 100 from 109, we get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 20

Let's proceed to step 5:
20 can be fit into 91 4 times, resulting in a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 1254.0
The remainder is 11 after subtracting 80 from 91.
Bring next digit (4) of the dividend behind the 11 and repeat the process: 114 / 20

Moving on to step 6:
20 goes into 114 5 times with a remainder of 14.
Use 5 as the next digit of our solution. 
Result so far: 12545.0
Deduct 100 from 114 and we're left 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.

Step 7:
If we divide 140 by 20, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 12545.7
If we subtract 140 from 140, 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 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 12545.7
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.

Going ahead to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12545.7
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.

The quotient of the division is 12545.7, and the remainder is 0.0.
