We divide 210625 by 2
Our goal is to divide 210625 by 2.

Advancing to step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 2 away from 2, we end up with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Going ahead to step 2:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtracting 0 from 1 leaves us with 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 2

Moving on to step 3:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 105.0
The remainder is 0 after subtracting 10 from 10.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

On to step 4:
If we divide 6 by 2, we get 3 and a remainder of 0.
The next digit of our result is 3. 
Result so far: 1053.0
If we subtract 6 from 6, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 2

Going ahead to step 5:
If we divide 2 by 2, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 10531.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 2

Let's proceed to step 6:
If we divide 5 by 2, we get 2 and a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 105312.0
If we subtract 4 from 5, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 7:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 105312.5
Subtract 10 from 10 to 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.

Going ahead to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 105312.5
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.

Going ahead to 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: 105312.5
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.

After the division, we end up with 105312.5 and a remainder of 0.0.
