Let's divide 250218 by 20
We're looking to find how many times 20 goes into 250218.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 20

Going ahead to step 2:
20 can be fit into 25 1 times, resulting in a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 20 from 25 and we're left with 5.
Append the next digit (0) from the dividend to 5 and continue with: 50 / 20

Going ahead to step 3:
50 divided by 20 is 2 with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Deduct 40 from 50 and we're left with 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 20

Step 4:
The number 20 fits into 102 5 times, leaving a remainder of 2.
Write down 5 as next digit of the result. 
Result so far: 125.0
If we subtract 100 from 102, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 20

Going ahead to step 5:
If we divide 21 by 20, we get 1 and a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1251.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 20

Going ahead to step 6:
If we divide 18 by 20, we get 0 and a remainder of 18.
Write down 0 as next digit of the result. 
Result so far: 12510.0
Deduct 0 from 18 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 7:
20 can be fit into 180 9 times, resulting in a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 12510.9
If we subtract 180 from 180, 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.

Advancing to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12510.9
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.

On to step 9:
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: 12510.9
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.

The quotient of the division is 12510.9, and the remainder is 0.0.
