We're dividing 15609 by 2 
Our goal is to divide 15609 by 2.

Let's proceed to step 1:
2 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

On to step 2:
The number 2 fits into 15 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 7.0
If we subtract 14 from 15, we get 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Advancing to step 3:
When dividing 16 by 2, we get 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
If we take 16 away from 16, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 2

Let's proceed to step 4:
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: 780.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 2

Let's proceed to step 5:
2 can be fit into 9 4 times, resulting in a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 7804.0
Subtract 8 from 9 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.

Advancing to step 6:
2 can be fit into 10 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7804.5
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.

Advancing to step 7:
2 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 7804.5
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.

On to step 8:
2 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 7804.5
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.

The final outcome is 7804.5, with a leftover of 0.0.
