31153816 ÷ 2 
We want to figure out the number of times 31153816 can be divided by 2.

Let's proceed to step 1:
3 divided by 2 is 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
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

Let's proceed to step 2:
11 divided by 2 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 15.0
Deduct 10 from 11 and we're left with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 2

Step 3:
The number 2 fits into 11 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 155.0
The remainder is 1 after subtracting 10 from 11.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Step 4:
2 can be fit into 15 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 1557.0
Deduct 14 from 15 and we're left with 1.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 2

Let's proceed to step 5:
The number 2 fits into 13 6 times, leaving a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 15576.0
If we subtract 12 from 13, we get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Going ahead to step 6:
When dividing 18 by 2, we get 9 with a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 155769.0
Deduct 18 from 18 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

On to step 7:
1 divided by 2 is 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 1557690.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

On to step 8:
16 divided by 2 is 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 15576908.0
If we take 16 away from 16, 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.

Step 9:
When dividing 0 by 2, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 15576908.0
Subtract 0 from 0 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.

Moving on to step 10:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 15576908.0
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 15576908.0 and a remainder of 0.0.
