Let's divide 149851 by 2
Let's see how many times 2 fits into 149851.

Step 1:
2 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Advancing to step 2:
When dividing 14 by 2, we get 7 with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we subtract 14 from 14, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Advancing to step 3:
The number 2 fits into 9 4 times, leaving a remainder of 1.
The next digit of our result is 4. 
Result so far: 74.0
Subtracting 8 from 9 leaves us with 1.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Going ahead to step 4:
The number 2 fits into 18 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 749.0
Subtract 18 from 18 to get 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 2

Let's proceed to step 5:
If we divide 5 by 2, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 7492.0
If we subtract 4 from 5, we get 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

On to step 6:
When dividing 11 by 2, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 74925.0
If we subtract 10 from 11, 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.

On to step 7:
10 divided by 2 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 74925.5
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.

Moving on to step 8:
2 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 74925.5
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.

Let's proceed to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 74925.5
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 quotient of the division is 74925.5, and the remainder is 0.0.
