161491 ÷ 2 
We're looking to find how many times 2 goes into 161491.

Moving on to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 2

Let's proceed to step 2:
If we divide 16 by 2, we get 8 and a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 0 after subtracting 16 from 16.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 2

Let's proceed to step 3:
2 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 80.0
If we take 0 away from 1, we end up with 1.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 2

Going ahead to step 4:
When dividing 14 by 2, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 807.0
Subtracting 14 from 14 leaves us with 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 2

Moving on to step 5:
The number 2 fits into 9 4 times, leaving a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 8074.0
If we take 8 away from 9, we end up with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Let's proceed to step 6:
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: 80745.0
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.
The next digit of our result is 5. 
Result so far: 80745.5
If we subtract 10 from 10, we 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.

Step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 80745.5
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.

Going ahead to step 9:
If we divide 0 by 2, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 80745.5
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.

The quotient of the division is 80745.5, and the remainder is 0.0.
