We look at the division of 18688249 by 2 
Let's see how many times 2 fits into 18688249.

Going ahead to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 2

Moving on to step 2:
18 divided by 2 is 9 with a remainder of 0.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 18 from 18 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 2

Step 3:
If we divide 6 by 2, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 93.0
Subtract 6 from 6 to get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 2

Advancing to step 4:
When dividing 8 by 2, we get 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 934.0
If we take 8 away from 8, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 2

Moving on to step 5:
2 can be fit into 8 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 9344.0
If we subtract 8 from 8, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

On to step 6:
When dividing 2 by 2, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 93441.0
If we take 2 away from 2, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 2

Advancing to step 7:
2 goes into 4 2 times with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 934412.0
Subtract 4 from 4 to get 0.
Include the next digit (9) from the dividend after 0, then repeat: 9 / 2

On to step 8:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 9344124.0
The remainder is 1 after subtracting 8 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 9:
2 goes into 10 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 9344124.5
Deduct 10 from 10 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.

On to step 10:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 9344124.5
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.

Step 11:
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: 9344124.5
If we take 0 away from 0, we end up 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 outcome is 9344124.5, with a leftover of 0.0.
