We divide 778791 by 77
Our goal is to divide 778791 by 77.

Let's proceed to step 1:
If we divide 7 by 77, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (7) of the dividend behind the 7 and repeat the process: 77 / 77

Advancing to step 2:
77 divided by 77 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 77 from 77 and we're left with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 77

Moving on to step 3:
77 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (7) from the dividend and append it to 8, then repeat: 87 / 77

On to step 4:
87 divided by 77 is 1 with a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we take 77 away from 87, we end up with 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 77

Advancing to step 5:
When dividing 109 by 77, we get 1 with a remainder of 32.
Write down 1 as next digit of the result. 
Result so far: 1011.0
Subtract 77 from 109 to get 32.
Bring next digit (1) of the dividend behind the 32 and repeat the process: 321 / 77

Let's proceed to step 6:
When dividing 321 by 77, we get 4 with a remainder of 13.
The number 4 becomes the next digit in our result. 
Result so far: 10114.0
Deduct 308 from 321 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
130 divided by 77 is 1 with a remainder of 53.
Put 1 as the next digit of the answer. 
Result so far: 10114.1
If we subtract 77 from 130, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 8:
77 can be fit into 530 6 times, resulting in a remainder of 68.
The next digit of our result is 6. 
Result so far: 10114.16
If we subtract 462 from 530, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
When dividing 680 by 77, we get 8 with a remainder of 64.
The next digit of our result is 8. 
Result so far: 10114.168
Subtract 616 from 680 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Advancing to step 10:
640 divided by 77 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 10114.1688
The remainder is 24 after subtracting 616 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The quotient of the division is 10114.1688, and the remainder is 0.00024.
