We look at the division of 162621 by 2 
Let's see how many times 2 fits into 162621.

On to step 1:
When dividing 1 by 2, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 2

Moving on to step 2:
2 can be fit into 16 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
The remainder is 0 after subtracting 16 from 16.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 2

Moving on to step 3:
2 goes into 2 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 81.0
Subtract 2 from 2 to get 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 2

On to step 4:
2 goes into 6 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 813.0
If we subtract 6 from 6, we get 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 2

Moving on to step 5:
2 divided by 2 is 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 8131.0
Subtract 2 from 2 to get 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 2

On to step 6:
When dividing 1 by 2, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 81310.0
If we take 0 away from 1, we end up 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.

Let's proceed to step 7:
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: 81310.5
Subtract 10 from 10 to 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.

Let's proceed to step 8:
0 divided by 2 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 81310.5
If we subtract 0 from 0, 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 9:
0 divided by 2 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 81310.5
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 81310.5, with a leftover of 0.0.
