2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 2 from 2 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20.0
If we subtract 0 from 0, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Moving on to step 3:
4 divided by 1 is 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 204.0
If we subtract 4 from 4, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Step 4:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 2041.0
If we subtract 1 from 1, we get 0.
Fetch the next digit (7) from the dividend, attach it to 0 and continue: 7 / 1

Moving on to step 5:
7 divided by 1 is 7 with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 20417.0
The remainder is 0 after subtracting 7 from 7.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 1

Step 6:
The number 1 fits into 8 8 times, leaving a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 204178.0
If we take 8 away from 8, we end up with 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

On to step 7:
1 goes into 4 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 2041784.0
If we take 4 away from 4, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Advancing to step 8:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 20417840.0
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 1, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20417840.0
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.

Let's proceed to step 10:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20417840.0
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 20417840.0 with a balance of 0.0.
