242717 ÷ 20 
We're looking to find how many times 20 goes into 242717.

Moving on to step 1:
If we divide 2 by 20, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (4) from the dividend, add it to 2, then carry on: 24 / 20

On to step 2:
24 divided by 20 is 1 with a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 20 from 24, we get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Let's proceed to step 3:
20 goes into 42 2 times with a remainder of 2.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 40 from 42 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 20

Let's proceed to step 4:
The number 20 fits into 27 1 times, leaving a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Deduct 20 from 27 and we're left with 7.
Take the next digit (1) from the dividend and append it to 7, then repeat: 71 / 20

Going ahead to step 5:
If we divide 71 by 20, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 1213.0
If we subtract 60 from 71, we get 11.
Append the next digit (7) from the dividend to 11 and continue with: 117 / 20

Step 6:
117 divided by 20 is 5 with a remainder of 17.
Use 5 as the next digit of our solution. 
Result so far: 12135.0
The remainder is 17 after subtracting 100 from 117.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 7:
170 divided by 20 is 8 with a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 12135.8
Subtract 160 from 170 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 8:
100 divided by 20 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 12135.85
If we subtract 100 from 100, 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 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 12135.85
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.

On to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 12135.85
If we take 0 away from 0, 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.

In conclusion, the division gives 12135.85 with a balance of 0.0.
