51376 ÷ 1 
Let's see how many times 1 fits into 51376.

Step 1:
5 divided by 1 is 5 with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtract 5 from 5 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Going ahead to step 2:
If we divide 1 by 1, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
If we subtract 1 from 1, we get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

On to step 3:
1 goes into 3 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 513.0
The remainder is 0 after subtracting 3 from 3.
Take the next digit (7) from the dividend and append it to 0, then repeat: 7 / 1

Let's proceed to step 4:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 5137.0
If we subtract 7 from 7, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 1

Going ahead to step 5:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 51376.0
The remainder is 0 after subtracting 6 from 6.
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 6:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51376.0
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 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 51376.0
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.

Our division results in 51376.0 with a remaining 0.0.
