669955 divided by 2 
Let's see how many times 2 fits into 669955.

On to step 1:
6 divided by 2 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 6 from 6 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 2

Going ahead to step 2:
6 divided by 2 is 3 with a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 33.0
If we subtract 6 from 6, we get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

On to step 3:
2 goes into 9 4 times with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 334.0
Subtract 8 from 9 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

Advancing to step 4:
When dividing 19 by 2, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 3349.0
Subtract 18 from 19 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 2

Advancing to step 5:
If we divide 15 by 2, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 33497.0
Subtract 14 from 15 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 2

Advancing to step 6:
When dividing 15 by 2, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 334977.0
If we take 14 away from 15, we end up with 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:
2 goes into 10 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 334977.5
The remainder is 0 after subtracting 10 from 10.
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:
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: 334977.5
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.

Moving on to step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 334977.5
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.

After the division, we end up with 334977.5 and a remainder of 0.0.
