We're dividing 615893 by 2 
We want to figure out the number of times 615893 can be divided by 2.

Advancing to step 1:
The number 2 fits into 6 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 6 from 6 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 2

Moving on to step 2:
The number 2 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (5) from the dividend after 1, then repeat: 15 / 2

Step 3:
The number 2 fits into 15 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 307.0
If we take 14 away from 15, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 2

Let's proceed to step 4:
If we divide 18 by 2, we get 9 and a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 3079.0
If we take 18 away from 18, we end up with 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 2

Moving on to step 5:
9 divided by 2 is 4 with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 30794.0
If we take 8 away from 9, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 2

On to step 6:
The number 2 fits into 13 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 307946.0
Deduct 12 from 13 and we're left 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.

On to step 7:
When dividing 10 by 2, we get 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 307946.5
If we take 10 away from 10, 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 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: 307946.5
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.

Moving on to step 9:
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: 307946.5
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.

Our division results in 307946.5 with a remaining 0.0.
