778540 ÷ 77 
Our goal is to divide 778540 by 77.

Moving on 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
Deduct 0 from 7 and we're left with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 77

Moving on to step 2:
When dividing 77 by 77, we get 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 77 from 77, we get 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 77

Going ahead to step 3:
The number 77 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 77

Going ahead to step 4:
77 can be fit into 85 1 times, resulting in a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 101.0
Subtracting 77 from 85 leaves us with 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 77

Let's proceed to step 5:
When dividing 84 by 77, we get 1 with a remainder of 7.
Record the quotient 1 as the next digit in the result. 
Result so far: 1011.0
Deduct 77 from 84 and we're left with 7.
Append the next digit (0) from the dividend to 7 and continue with: 70 / 77

Let's proceed to step 6:
When dividing 70 by 77, we get 0 with a remainder of 70.
The next digit of our result is 0. 
Result so far: 10110.0
If we subtract 0 from 70, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 7:
77 can be fit into 700 9 times, resulting in a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 10110.9
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 8:
77 goes into 70 0 times with a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 10110.9
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 9:
If we divide 700 by 77, we get 9 and a remainder of 7.
The next digit of our result is 9. 
Result so far: 10110.909
Subtract 693 from 700 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 10:
If we divide 70 by 77, we get 0 and a remainder of 70.
The number 0 becomes the next digit in our result. 
Result so far: 10110.909
Subtracting 0 from 70 leaves us with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 11:
77 can be fit into 700 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 10110.90909
Subtracting 693 from 700 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 12:
If we divide 70 by 77, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10110.90909
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Let's proceed to step 13:
77 can be fit into 700 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 10110.9090909
If we take 693 away from 700, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 14:
If we divide 70 by 77, we get 0 and a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10110.9090909
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

After the division, we end up with 10110.9090909 and a remainder of 7e-08.
