48393759 ÷ 77 
We want to figure out the number of times 48393759 can be divided by 77.

Going ahead to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 77

Advancing to step 2:
If we divide 48 by 77, we get 0 and a remainder of 48.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 48, we get 48.
Fetch the next digit (3) from the dividend, attach it to 48 and continue: 483 / 77

On to step 3:
If we divide 483 by 77, we get 6 and a remainder of 21.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 462 from 483, we get 21.
Take the next digit (9) from the dividend and append it to 21, then repeat: 219 / 77

Moving on to step 4:
77 goes into 219 2 times with a remainder of 65.
The next digit of our result is 2. 
Result so far: 62.0
Subtracting 154 from 219 leaves us with 65.
Take the next digit (3) from the dividend and append it to 65, then repeat: 653 / 77

Step 5:
77 can be fit into 653 8 times, resulting in a remainder of 37.
Record the quotient 8 as the next digit in the result. 
Result so far: 628.0
Deduct 616 from 653 and we're left with 37.
Append the next digit (7) from the dividend to 37 and continue with: 377 / 77

On to step 6:
The number 77 fits into 377 4 times, leaving a remainder of 69.
Write down 4 as next digit of the result. 
Result so far: 6284.0
If we subtract 308 from 377, we get 69.
Include the next digit (5) from the dividend after 69, then repeat: 695 / 77

On to step 7:
When dividing 695 by 77, we get 9 with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 62849.0
Deduct 693 from 695 and we're left with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 77

Going ahead to step 8:
If we divide 29 by 77, we get 0 and a remainder of 29.
Put 0 as the next digit of the answer. 
Result so far: 628490.0
Deduct 0 from 29 and we're left with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Let's proceed to step 9:
The number 77 fits into 290 3 times, leaving a remainder of 59.
Put 3 as the next digit of the answer. 
Result so far: 628490.3
Deduct 231 from 290 and we're left with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Step 10:
590 divided by 77 is 7 with a remainder of 51.
Write down 7 as next digit of the result. 
Result so far: 628490.37
If we subtract 539 from 590, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Step 11:
When dividing 510 by 77, we get 6 with a remainder of 48.
Write down 6 as next digit of the result. 
Result so far: 628490.376
Subtract 462 from 510 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 12:
77 can be fit into 480 6 times, resulting in a remainder of 18.
The number 6 becomes the next digit in our result. 
Result so far: 628490.3766
The remainder is 18 after subtracting 462 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final outcome is 628490.3766, with a leftover of 0.00018.
