355139 ÷ 2 
We're looking to find how many times 2 goes into 355139.

On to step 1:
The number 2 fits into 3 1 times, leaving a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 2 from 3 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Going ahead to step 2:
If we divide 15 by 2, we get 7 and a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we take 14 away from 15, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Going ahead to step 3:
15 divided by 2 is 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 177.0
Subtract 14 from 15 to get 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

Step 4:
2 goes into 11 5 times with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1775.0
If we take 10 away from 11, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

Let's proceed to step 5:
2 can be fit into 13 6 times, resulting in a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 17756.0
Subtract 12 from 13 to get 1.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 2

On to step 6:
The number 2 fits into 19 9 times, leaving a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 177569.0
Deduct 18 from 19 and we're left 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:
When dividing 10 by 2, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 177569.5
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.

Step 8:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 177569.5
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.

Advancing 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: 177569.5
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.

Our division results in 177569.5 with a remaining 0.0.
