We look at the division of 51919438 by 768 
We're looking to find how many times 768 goes into 51919438.

Let's proceed to step 1:
The number 768 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 768

Step 2:
51 divided by 768 is 0 with a remainder of 51.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (9) from the dividend after 51, then repeat: 519 / 768

On to step 3:
When dividing 519 by 768, we get 0 with a remainder of 519.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 519, we end up with 519.
Bring next digit (1) of the dividend behind the 519 and repeat the process: 5191 / 768

Moving on to step 4:
5191 divided by 768 is 6 with a remainder of 583.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 4608 from 5191 to get 583.
Fetch the next digit (9) from the dividend, attach it to 583 and continue: 5839 / 768

Moving on to step 5:
5839 divided by 768 is 7 with a remainder of 463.
Write down 7 as next digit of the result. 
Result so far: 67.0
Subtract 5376 from 5839 to get 463.
Bring next digit (4) of the dividend behind the 463 and repeat the process: 4634 / 768

Advancing to step 6:
768 goes into 4634 6 times with a remainder of 26.
Record the quotient 6 as the next digit in the result. 
Result so far: 676.0
If we take 4608 away from 4634, we end up with 26.
Take the next digit (3) from the dividend and append it to 26, then repeat: 263 / 768

Going ahead to step 7:
768 goes into 263 0 times with a remainder of 263.
The number 0 becomes the next digit in our result. 
Result so far: 6760.0
If we subtract 0 from 263, we get 263.
Take the next digit (8) from the dividend and append it to 263, then repeat: 2638 / 768

Advancing to step 8:
The number 768 fits into 2638 3 times, leaving a remainder of 334.
Put 3 as the next digit of the answer. 
Result so far: 67603.0
If we take 2304 away from 2638, we end up with 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 9:
768 can be fit into 3340 4 times, resulting in a remainder of 268.
The number 4 becomes the next digit in our result. 
Result so far: 67603.4
Deduct 3072 from 3340 and we're left with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 10:
768 goes into 2680 3 times with a remainder of 376.
Put 3 as the next digit of the answer. 
Result so far: 67603.43
Subtract 2304 from 2680 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Moving on to step 11:
When dividing 3760 by 768, we get 4 with a remainder of 688.
Record the quotient 4 as the next digit in the result. 
Result so far: 67603.434
If we take 3072 away from 3760, we end up with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Going ahead to step 12:
When dividing 6880 by 768, we get 8 with a remainder of 736.
Put 8 as the next digit of the answer. 
Result so far: 67603.4348
Subtract 6144 from 6880 to get 736.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7360, and continue the process.

Step 13:
When dividing 7360 by 768, we get 9 with a remainder of 448.
Put 9 as the next digit of the answer. 
Result so far: 67603.43489
The remainder is 448 after subtracting 6912 from 7360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4480, and continue the process.

Advancing to step 14:
768 goes into 4480 5 times with a remainder of 640.
Write down 5 as next digit of the result. 
Result so far: 67603.434895
Deduct 3840 from 4480 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 15:
The number 768 fits into 6400 8 times, leaving a remainder of 256.
Record the quotient 8 as the next digit in the result. 
Result so far: 67603.4348958
Subtract 6144 from 6400 to get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Moving on to step 16:
If we divide 2560 by 768, we get 3 and a remainder of 256.
Record the quotient 3 as the next digit in the result. 
Result so far: 67603.43489583
If we take 2304 away from 2560, we end up with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

In conclusion, the division gives 67603.43489583 with a balance of 2.56e-07.
