We divide 77515202 by 78
Let's see how many times 78 fits into 77515202.

Let's proceed to step 1:
78 goes into 7 0 times with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 78

On to step 2:
78 can be fit into 77 0 times, resulting in a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 77 after subtracting 0 from 77.
Bring next digit (5) of the dividend behind the 77 and repeat the process: 775 / 78

Let's proceed to step 3:
78 goes into 775 9 times with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 702 from 775 leaves us with 73.
Fetch the next digit (1) from the dividend, attach it to 73 and continue: 731 / 78

Going ahead to step 4:
The number 78 fits into 731 9 times, leaving a remainder of 29.
The next digit of our result is 9. 
Result so far: 99.0
Subtract 702 from 731 to get 29.
Fetch the next digit (5) from the dividend, attach it to 29 and continue: 295 / 78

Advancing to step 5:
The number 78 fits into 295 3 times, leaving a remainder of 61.
The next digit of our result is 3. 
Result so far: 993.0
If we take 234 away from 295, we end up with 61.
Grab the next digit (2) from the dividend, add it to 61, then carry on: 612 / 78

Going ahead to step 6:
78 can be fit into 612 7 times, resulting in a remainder of 66.
Use 7 as the next digit of our solution. 
Result so far: 9937.0
Deduct 546 from 612 and we're left with 66.
Fetch the next digit (0) from the dividend, attach it to 66 and continue: 660 / 78

Moving on to step 7:
If we divide 660 by 78, we get 8 and a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 99378.0
Subtracting 624 from 660 leaves us with 36.
Bring next digit (2) of the dividend behind the 36 and repeat the process: 362 / 78

Moving on to step 8:
78 goes into 362 4 times with a remainder of 50.
Record the quotient 4 as the next digit in the result. 
Result so far: 993784.0
Deduct 312 from 362 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 9:
The number 78 fits into 500 6 times, leaving a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 993784.6
Deduct 468 from 500 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 10:
When dividing 320 by 78, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 993784.64
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
78 goes into 80 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 993784.641
Subtracting 78 from 80 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 12:
If we divide 20 by 78, we get 0 and a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 993784.641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
78 can be fit into 200 2 times, resulting in a remainder of 44.
The number 2 becomes the next digit in our result. 
Result so far: 993784.64102
Subtracting 156 from 200 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 14:
440 divided by 78 is 5 with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 993784.641025
Deduct 390 from 440 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 15:
78 can be fit into 500 6 times, resulting in a remainder of 32.
The next digit of our result is 6. 
Result so far: 993784.6410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Going ahead to step 16:
78 goes into 320 4 times with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 993784.64102564
If we take 312 away from 320, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 993784.64102564 with a balance of 8e-09.
