We're dividing 51275555 by 768 
We're looking to find how many times 768 goes into 51275555.

Step 1:
5 divided by 768 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 768

Let's proceed to step 2:
If we divide 51 by 768, we get 0 and a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (2) from the dividend and append it to 51, then repeat: 512 / 768

Advancing to step 3:
768 goes into 512 0 times with a remainder of 512.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 512 and we're left with 512.
Append the next digit (7) from the dividend to 512 and continue with: 5127 / 768

Step 4:
When dividing 5127 by 768, we get 6 with a remainder of 519.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 4608 from 5127 and we're left with 519.
Append the next digit (5) from the dividend to 519 and continue with: 5195 / 768

On to step 5:
If we divide 5195 by 768, we get 6 and a remainder of 587.
Write down 6 as next digit of the result. 
Result so far: 66.0
Deduct 4608 from 5195 and we're left with 587.
Fetch the next digit (5) from the dividend, attach it to 587 and continue: 5875 / 768

Going ahead to step 6:
5875 divided by 768 is 7 with a remainder of 499.
Put 7 as the next digit of the answer. 
Result so far: 667.0
Deduct 5376 from 5875 and we're left with 499.
Grab the next digit (5) from the dividend, add it to 499, then carry on: 4995 / 768

Let's proceed to step 7:
When dividing 4995 by 768, we get 6 with a remainder of 387.
Record the quotient 6 as the next digit in the result. 
Result so far: 6676.0
If we subtract 4608 from 4995, we get 387.
Take the next digit (5) from the dividend and append it to 387, then repeat: 3875 / 768

Let's proceed to step 8:
The number 768 fits into 3875 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 66765.0
If we subtract 3840 from 3875, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 768 fits into 350 0 times, leaving a remainder of 350.
Write down 0 as next digit of the result. 
Result so far: 66765.0
Deduct 0 from 350 and we're left with 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3500, and continue the process.

On to step 10:
3500 divided by 768 is 4 with a remainder of 428.
Record the quotient 4 as the next digit in the result. 
Result so far: 66765.04
The remainder is 428 after subtracting 3072 from 3500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 11:
The number 768 fits into 4280 5 times, leaving a remainder of 440.
Write down 5 as next digit of the result. 
Result so far: 66765.045
Deduct 3840 from 4280 and we're left with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Let's proceed to step 12:
The number 768 fits into 4400 5 times, leaving a remainder of 560.
Use 5 as the next digit of our solution. 
Result so far: 66765.0455
The remainder is 560 after subtracting 3840 from 4400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5600, and continue the process.

The final outcome is 66765.0455, with a leftover of 0.0056.
