We're dividing 321155 by 2 
We're looking to find how many times 2 goes into 321155.

Advancing to step 1:
If we divide 3 by 2, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 1 after subtracting 2 from 3.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 2

On to step 2:
When dividing 12 by 2, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 16.0
Deduct 12 from 12 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

On to step 3:
1 divided by 2 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 160.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (1) from the dividend and append it to 1, then repeat: 11 / 2

On to step 4:
11 divided by 2 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 1605.0
Deduct 10 from 11 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Step 5:
If we divide 15 by 2, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 16057.0
The remainder is 1 after subtracting 14 from 15.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 6:
2 goes into 15 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 160577.0
Deduct 14 from 15 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.

Advancing to step 7:
If we divide 10 by 2, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 160577.5
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.

On to step 8:
2 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 160577.5
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.

On to step 9:
2 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 160577.5
Subtracting 0 from 0 leaves us 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.

The final outcome is 160577.5, with a leftover of 0.0.
