77784061 divided by 666 
We want to divide 77784061 by 666.

On to step 1:
If we divide 7 by 666, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 666

Going ahead to step 2:
If we divide 77 by 666, we get 0 and a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 666

Let's proceed to step 3:
666 can be fit into 777 1 times, resulting in a remainder of 111.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 666 from 777, we get 111.
Bring next digit (8) of the dividend behind the 111 and repeat the process: 1118 / 666

Going ahead to step 4:
When dividing 1118 by 666, we get 1 with a remainder of 452.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Subtract 666 from 1118 to get 452.
Take the next digit (4) from the dividend and append it to 452, then repeat: 4524 / 666

Step 5:
666 can be fit into 4524 6 times, resulting in a remainder of 528.
Use 6 as the next digit of our solution. 
Result so far: 116.0
If we take 3996 away from 4524, we end up with 528.
Take the next digit (0) from the dividend and append it to 528, then repeat: 5280 / 666

Let's proceed to step 6:
666 can be fit into 5280 7 times, resulting in a remainder of 618.
Put 7 as the next digit of the answer. 
Result so far: 1167.0
Subtracting 4662 from 5280 leaves us with 618.
Bring next digit (6) of the dividend behind the 618 and repeat the process: 6186 / 666

Going ahead to step 7:
If we divide 6186 by 666, we get 9 and a remainder of 192.
Use 9 as the next digit of our solution. 
Result so far: 11679.0
If we subtract 5994 from 6186, we get 192.
Append the next digit (1) from the dividend to 192 and continue with: 1921 / 666

Going ahead to step 8:
The number 666 fits into 1921 2 times, leaving a remainder of 589.
The number 2 becomes the next digit in our result. 
Result so far: 116792.0
The remainder is 589 after subtracting 1332 from 1921.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5890, and continue the process.

Advancing to step 9:
If we divide 5890 by 666, we get 8 and a remainder of 562.
Put 8 as the next digit of the answer. 
Result so far: 116792.8
If we take 5328 away from 5890, we end up with 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

Moving on to step 10:
When dividing 5620 by 666, we get 8 with a remainder of 292.
Record the quotient 8 as the next digit in the result. 
Result so far: 116792.88
Subtract 5328 from 5620 to get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

The final result is 116792.88 with a remainder of 0.292.
