We divide 666151 by 2
Let's see how many times 2 fits into 666151.

Let's proceed to step 1:
When dividing 6 by 2, we get 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Step 2:
6 divided by 2 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 33.0
Deduct 6 from 6 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 2

Going ahead to step 3:
2 goes into 6 3 times with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 333.0
Subtracting 6 from 6 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Step 4:
If we divide 1 by 2, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 3330.0
If we subtract 0 from 1, we get 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Step 5:
If we divide 15 by 2, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 33307.0
Subtract 14 from 15 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Advancing to step 6:
11 divided by 2 is 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 333075.0
Subtract 10 from 11 to 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.

Step 7:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 333075.5
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.

Advancing to step 8:
0 divided by 2 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 333075.5
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.

Going ahead to step 9:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 333075.5
Deduct 0 from 0 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.

After the division, we end up with 333075.5 and a remainder of 0.0.
