We're dividing 77906027 by 518 
Our goal is to divide 77906027 by 518.

Step 1:
If we divide 7 by 518, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 518

Let's proceed to step 2:
518 can be fit into 77 0 times, resulting in a remainder of 77.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Bring next digit (9) of the dividend behind the 77 and repeat the process: 779 / 518

Step 3:
779 divided by 518 is 1 with a remainder of 261.
The next digit of our result is 1. 
Result so far: 1.0
If we take 518 away from 779, we end up with 261.
Grab the next digit (0) from the dividend, add it to 261, then carry on: 2610 / 518

Moving on to step 4:
When dividing 2610 by 518, we get 5 with a remainder of 20.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Deduct 2590 from 2610 and we're left with 20.
Include the next digit (6) from the dividend after 20, then repeat: 206 / 518

Going ahead to step 5:
When dividing 206 by 518, we get 0 with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 150.0
Subtracting 0 from 206 leaves us with 206.
Bring next digit (0) of the dividend behind the 206 and repeat the process: 2060 / 518

Going ahead to step 6:
2060 divided by 518 is 3 with a remainder of 506.
Write down 3 as next digit of the result. 
Result so far: 1503.0
Subtracting 1554 from 2060 leaves us with 506.
Take the next digit (2) from the dividend and append it to 506, then repeat: 5062 / 518

Let's proceed to step 7:
When dividing 5062 by 518, we get 9 with a remainder of 400.
Use 9 as the next digit of our solution. 
Result so far: 15039.0
If we take 4662 away from 5062, we end up with 400.
Bring next digit (7) of the dividend behind the 400 and repeat the process: 4007 / 518

Let's proceed to step 8:
518 goes into 4007 7 times with a remainder of 381.
The number 7 becomes the next digit in our result. 
Result so far: 150397.0
Subtract 3626 from 4007 to get 381.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3810, and continue the process.

Step 9:
518 can be fit into 3810 7 times, resulting in a remainder of 184.
Write down 7 as next digit of the result. 
Result so far: 150397.7
Subtracting 3626 from 3810 leaves us with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Moving on to step 10:
When dividing 1840 by 518, we get 3 with a remainder of 286.
Use 3 as the next digit of our solution. 
Result so far: 150397.73
Deduct 1554 from 1840 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Going ahead to step 11:
The number 518 fits into 2860 5 times, leaving a remainder of 270.
Write down 5 as next digit of the result. 
Result so far: 150397.735
If we subtract 2590 from 2860, we get 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Going ahead to step 12:
When dividing 2700 by 518, we get 5 with a remainder of 110.
Write down 5 as next digit of the result. 
Result so far: 150397.7355
Subtracting 2590 from 2700 leaves us with 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

The final result is 150397.7355 with a remainder of 0.0011.
