780145 divided by 78 
Let's see how many times 78 fits into 780145.

On to step 1:
7 divided by 78 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 78

Going ahead to step 2:
If we divide 78 by 78, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 78 from 78.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 78

Going ahead to step 3:
The number 78 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 0 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 78

Step 4:
1 divided by 78 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 100.0
If we take 0 away from 1, we end up with 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 78

Advancing to step 5:
14 divided by 78 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 1000.0
Subtract 0 from 14 to get 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 78

Moving on to step 6:
If we divide 145 by 78, we get 1 and a remainder of 67.
The number 1 becomes the next digit in our result. 
Result so far: 10001.0
If we subtract 78 from 145, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

On to step 7:
If we divide 670 by 78, we get 8 and a remainder of 46.
Use 8 as the next digit of our solution. 
Result so far: 10001.8
If we take 624 away from 670, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 8:
78 goes into 460 5 times with a remainder of 70.
The next digit of our result is 5. 
Result so far: 10001.85
Deduct 390 from 460 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.

Let's proceed to step 9:
700 divided by 78 is 8 with a remainder of 76.
Record the quotient 8 as the next digit in the result. 
Result so far: 10001.858
Deduct 624 from 700 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 10:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 10001.8589
Subtract 702 from 760 to get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 11:
When dividing 580 by 78, we get 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 10001.85897
Deduct 546 from 580 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 12:
The number 78 fits into 340 4 times, leaving a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 10001.858974
Subtracting 312 from 340 leaves us with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 13:
280 divided by 78 is 3 with a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 10001.8589743
Subtracting 234 from 280 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Step 14:
When dividing 460 by 78, we get 5 with a remainder of 70.
Use 5 as the next digit of our solution. 
Result so far: 10001.85897435
Deduct 390 from 460 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.

The final result is 10001.85897435 with a remainder of 7e-08.
