Let's divide 102103 by 2
We want to figure out the number of times 102103 can be divided by 2.

Going ahead to step 1:
2 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Going ahead to step 2:
When dividing 10 by 2, we get 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 10 from 10 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 2

Advancing to step 3:
2 divided by 2 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 2 from 2 to get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Advancing to step 4:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 510.0
The remainder is 1 after subtracting 0 from 1.
Append the next digit (0) from the dividend to 1 and continue with: 10 / 2

Going ahead to step 5:
If we divide 10 by 2, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5105.0
Subtract 10 from 10 to get 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

On to step 6:
If we divide 3 by 2, we get 1 and a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 51051.0
If we subtract 2 from 3, 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.

Advancing to step 7:
10 divided by 2 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 51051.5
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.

Moving on to step 8:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 51051.5
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.

Step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 51051.5
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.

The final result is 51051.5 with a remainder of 0.0.
