We look at the division of 248619 by 2 
We want to figure out the number of times 248619 can be divided by 2.

Going ahead to step 1:
2 can be fit into 2 1 times, resulting in a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 2

Going ahead to step 2:
When dividing 4 by 2, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 4 from 4 and we're left with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 2

Going ahead to step 3:
If we divide 8 by 2, we get 4 and a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 124.0
Subtract 8 from 8 to get 0.
Bring next digit (6) of the dividend behind the 0 and repeat the process: 6 / 2

On to step 4:
2 goes into 6 3 times with a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 1243.0
Deduct 6 from 6 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Going ahead to step 5:
1 divided by 2 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 12430.0
Subtract 0 from 1 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Let's proceed to step 6:
2 goes into 19 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 124309.0
The remainder is 1 after subtracting 18 from 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
10 divided by 2 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 124309.5
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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 124309.5
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:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 124309.5
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.

The final result is 124309.5 with a remainder of 0.0.
