70161 divided by 2 
We want to figure out the number of times 70161 can be divided by 2.

On to step 1:
The number 2 fits into 7 3 times, leaving a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 6 from 7, we get 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 2

Let's proceed to step 2:
The number 2 fits into 10 5 times, leaving a remainder of 0.
The next digit of our result is 5. 
Result so far: 35.0
Subtracting 10 from 10 leaves us with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

Moving on to step 3:
2 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 350.0
Subtract 0 from 1 to get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

On to step 4:
The number 2 fits into 16 8 times, leaving a remainder of 0.
The next digit of our result is 8. 
Result so far: 3508.0
Subtract 16 from 16 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 2

Let's proceed to step 5:
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: 35080.0
Subtracting 0 from 1 leaves us 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.

Going ahead to step 6:
The number 2 fits into 10 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 35080.5
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.

Going ahead to step 7:
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: 35080.5
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 8:
If we divide 0 by 2, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 35080.5
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.

After the division, we end up with 35080.5 and a remainder of 0.0.
