We're dividing 57186518 by 772 
Let's see how many times 772 fits into 57186518.

Going ahead to step 1:
772 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 772

Step 2:
772 can be fit into 57 0 times, resulting in a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 772

Going ahead to step 3:
571 divided by 772 is 0 with a remainder of 571.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 571, we get 571.
Bring next digit (8) of the dividend behind the 571 and repeat the process: 5718 / 772

Advancing to step 4:
The number 772 fits into 5718 7 times, leaving a remainder of 314.
Use 7 as the next digit of our solution. 
Result so far: 7.0
If we subtract 5404 from 5718, we get 314.
Include the next digit (6) from the dividend after 314, then repeat: 3146 / 772

Going ahead to step 5:
When dividing 3146 by 772, we get 4 with a remainder of 58.
Write down 4 as next digit of the result. 
Result so far: 74.0
If we take 3088 away from 3146, we end up with 58.
Fetch the next digit (5) from the dividend, attach it to 58 and continue: 585 / 772

Moving on to step 6:
When dividing 585 by 772, we get 0 with a remainder of 585.
Use 0 as the next digit of our solution. 
Result so far: 740.0
Subtract 0 from 585 to get 585.
Grab the next digit (1) from the dividend, add it to 585, then carry on: 5851 / 772

Moving on to step 7:
When dividing 5851 by 772, we get 7 with a remainder of 447.
Use 7 as the next digit of our solution. 
Result so far: 7407.0
Deduct 5404 from 5851 and we're left with 447.
Take the next digit (8) from the dividend and append it to 447, then repeat: 4478 / 772

On to step 8:
If we divide 4478 by 772, we get 5 and a remainder of 618.
Use 5 as the next digit of our solution. 
Result so far: 74075.0
Subtracting 3860 from 4478 leaves us with 618.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6180, and continue the process.

Moving on to step 9:
The number 772 fits into 6180 8 times, leaving a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 74075.8
Subtracting 6176 from 6180 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
772 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 74075.8
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 11:
400 divided by 772 is 0 with a remainder of 400.
Use 0 as the next digit of our solution. 
Result so far: 74075.8
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 74075.8, with a leftover of 0.04.
