We divide 212031 by 2
We want to figure out the number of times 212031 can be divided by 2.

On to step 1:
If we divide 2 by 2, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 2 from 2, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Moving on to step 2:
If we divide 1 by 2, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 2

Going ahead to step 3:
12 divided by 2 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 106.0
Subtract 12 from 12 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 2

Step 4:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1060.0
If we take 0 away from 0, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 2

On to step 5:
When dividing 3 by 2, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 10601.0
Deduct 2 from 3 and we're left with 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 6:
If we divide 11 by 2, we get 5 and a remainder of 1.
The next digit of our result is 5. 
Result so far: 106015.0
Subtracting 10 from 11 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 106015.5
Subtracting 10 from 10 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 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 106015.5
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.

Step 9:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 106015.5
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.

Our division results in 106015.5 with a remaining 0.0.
