We look at the division of 51156 by 2 
Our goal is to divide 51156 by 2.

On to step 1:
5 divided by 2 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 4 from 5 and we're left with 1.
Append the next digit (1) from the dividend to 1 and continue with: 11 / 2

Going ahead to step 2:
If we divide 11 by 2, we get 5 and a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 25.0
Deduct 10 from 11 and we're left with 1.
Fetch the next digit (1) from the dividend, attach it to 1 and continue: 11 / 2

Advancing to step 3:
11 divided by 2 is 5 with a remainder of 1.
Record the quotient 5 as the next digit in the result. 
Result so far: 255.0
Subtracting 10 from 11 leaves us with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 2

Step 4:
When dividing 15 by 2, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 2557.0
Subtracting 14 from 15 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 2

Let's proceed to step 5:
The number 2 fits into 16 8 times, leaving a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 25578.0
If we take 16 away from 16, 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 6:
0 divided by 2 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 25578.0
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.

Step 7:
The number 2 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 25578.0
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 25578.0, with a leftover of 0.0.
