We look at the division of 142583 by 2 
We want to figure out the number of times 142583 can be divided by 2.

On to step 1:
The number 2 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 2

Advancing to step 2:
2 can be fit into 14 7 times, resulting in a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 14 from 14, we get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 2

Let's proceed to step 3:
2 goes into 2 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 71.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 2

Advancing to step 4:
The number 2 fits into 5 2 times, leaving a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 712.0
The remainder is 1 after subtracting 4 from 5.
Grab the next digit (8) from the dividend, add it to 1, then carry on: 18 / 2

Step 5:
2 can be fit into 18 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 7129.0
Deduct 18 from 18 and we're left with 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 2

Let's proceed to step 6:
When dividing 3 by 2, we get 1 with a remainder of 1.
Put 1 as the next digit of the answer. 
Result so far: 71291.0
The remainder is 1 after subtracting 2 from 3.
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:
If we divide 10 by 2, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 71291.5
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:
When dividing 0 by 2, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 71291.5
Subtract 0 from 0 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.

Step 9:
The number 2 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 71291.5
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.

The final outcome is 71291.5, with a leftover of 0.0.
