We look at the division of 76402049 by 78 
Our goal is to divide 76402049 by 78.

Advancing to step 1:
78 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (6) from the dividend to 7 and continue with: 76 / 78

Step 2:
When dividing 76 by 78, we get 0 with a remainder of 76.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Append the next digit (4) from the dividend to 76 and continue with: 764 / 78

Going ahead to step 3:
78 goes into 764 9 times with a remainder of 62.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 702 from 764, we get 62.
Append the next digit (0) from the dividend to 62 and continue with: 620 / 78

Step 4:
78 can be fit into 620 7 times, resulting in a remainder of 74.
Put 7 as the next digit of the answer. 
Result so far: 97.0
Deduct 546 from 620 and we're left with 74.
Take the next digit (2) from the dividend and append it to 74, then repeat: 742 / 78

On to step 5:
If we divide 742 by 78, we get 9 and a remainder of 40.
The number 9 becomes the next digit in our result. 
Result so far: 979.0
If we take 702 away from 742, we end up with 40.
Fetch the next digit (0) from the dividend, attach it to 40 and continue: 400 / 78

Advancing to step 6:
When dividing 400 by 78, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 9795.0
Subtracting 390 from 400 leaves us with 10.
Include the next digit (4) from the dividend after 10, then repeat: 104 / 78

Let's proceed to step 7:
104 divided by 78 is 1 with a remainder of 26.
Record the quotient 1 as the next digit in the result. 
Result so far: 97951.0
Subtract 78 from 104 to get 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 78

Advancing to step 8:
78 can be fit into 269 3 times, resulting in a remainder of 35.
Write down 3 as next digit of the result. 
Result so far: 979513.0
Subtracting 234 from 269 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 9:
78 can be fit into 350 4 times, resulting in a remainder of 38.
The next digit of our result is 4. 
Result so far: 979513.4
The remainder is 38 after subtracting 312 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
The number 78 fits into 380 4 times, leaving a remainder of 68.
The next digit of our result is 4. 
Result so far: 979513.44
If we take 312 away from 380, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

The quotient of the division is 979513.44, and the remainder is 0.068.
