We look at the division of 211224 by 1 
Our goal is to divide 211224 by 1.

Advancing to step 1:
1 can be fit into 2 2 times, resulting in a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Step 2:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 21.0
Subtracting 1 from 1 leaves us with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Advancing to step 3:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 211.0
The remainder is 0 after subtracting 1 from 1.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Step 4:
1 goes into 2 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2112.0
If we subtract 2 from 2, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Step 5:
If we divide 2 by 1, we get 2 and a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 21122.0
Subtract 2 from 2 to get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Going ahead to step 6:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 211224.0
Subtracting 4 from 4 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 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 211224.0
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 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 211224.0
Deduct 0 from 0 and we're left 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 final result is 211224.0 with a remainder of 0.0.
