Let's divide 66780854 by 788
Our goal is to divide 66780854 by 788.

Let's proceed to step 1:
788 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 788

On to step 2:
When dividing 66 by 788, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 66 after subtracting 0 from 66.
Fetch the next digit (7) from the dividend, attach it to 66 and continue: 667 / 788

On to step 3:
667 divided by 788 is 0 with a remainder of 667.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 667, we get 667.
Append the next digit (8) from the dividend to 667 and continue with: 6678 / 788

Going ahead to step 4:
788 can be fit into 6678 8 times, resulting in a remainder of 374.
Put 8 as the next digit of the answer. 
Result so far: 8.0
If we take 6304 away from 6678, we end up with 374.
Fetch the next digit (0) from the dividend, attach it to 374 and continue: 3740 / 788

Step 5:
3740 divided by 788 is 4 with a remainder of 588.
The number 4 becomes the next digit in our result. 
Result so far: 84.0
Subtract 3152 from 3740 to get 588.
Include the next digit (8) from the dividend after 588, then repeat: 5888 / 788

Let's proceed to step 6:
When dividing 5888 by 788, we get 7 with a remainder of 372.
Record the quotient 7 as the next digit in the result. 
Result so far: 847.0
If we subtract 5516 from 5888, we get 372.
Bring next digit (5) of the dividend behind the 372 and repeat the process: 3725 / 788

Advancing to step 7:
If we divide 3725 by 788, we get 4 and a remainder of 573.
The next digit of our result is 4. 
Result so far: 8474.0
Subtract 3152 from 3725 to get 573.
Append the next digit (4) from the dividend to 573 and continue with: 5734 / 788

Going ahead to step 8:
788 goes into 5734 7 times with a remainder of 218.
Record the quotient 7 as the next digit in the result. 
Result so far: 84747.0
Subtracting 5516 from 5734 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 9:
788 goes into 2180 2 times with a remainder of 604.
Put 2 as the next digit of the answer. 
Result so far: 84747.2
The remainder is 604 after subtracting 1576 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6040, and continue the process.

On to step 10:
6040 divided by 788 is 7 with a remainder of 524.
Put 7 as the next digit of the answer. 
Result so far: 84747.27
Deduct 5516 from 6040 and we're left with 524.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5240, and continue the process.

Advancing to step 11:
If we divide 5240 by 788, we get 6 and a remainder of 512.
Use 6 as the next digit of our solution. 
Result so far: 84747.276
The remainder is 512 after subtracting 4728 from 5240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5120, and continue the process.

Let's proceed to step 12:
If we divide 5120 by 788, we get 6 and a remainder of 392.
The next digit of our result is 6. 
Result so far: 84747.2766
Deduct 4728 from 5120 and we're left with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

The final outcome is 84747.2766, with a leftover of 0.00392.
