155890 ÷ 2 
Our goal is to divide 155890 by 2.

Moving on to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Going ahead to step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 7.0
If we subtract 14 from 15, we get 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 2

Going ahead to step 3:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 77.0
Subtract 14 from 15 to get 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 2

Going ahead to step 4:
2 goes into 18 9 times with a remainder of 0.
Write down 9 as next digit of the result. 
Result so far: 779.0
Subtract 18 from 18 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Going ahead to step 5:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 7794.0
Subtracting 8 from 9 leaves us with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 2

Advancing to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 77945.0
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 7:
2 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 77945.0
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.

Let's proceed to step 8:
When dividing 0 by 2, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 77945.0
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.

The quotient of the division is 77945.0, and the remainder is 0.0.
