581449 divided by 78 
We want to figure out the number of times 581449 can be divided by 78.

Step 1:
78 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 78

Step 2:
78 can be fit into 58 0 times, resulting in a remainder of 58.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 58, we get 58.
Include the next digit (1) from the dividend after 58, then repeat: 581 / 78

On to step 3:
78 can be fit into 581 7 times, resulting in a remainder of 35.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 546 from 581 and we're left with 35.
Take the next digit (4) from the dividend and append it to 35, then repeat: 354 / 78

On to step 4:
If we divide 354 by 78, we get 4 and a remainder of 42.
The next digit of our result is 4. 
Result so far: 74.0
The remainder is 42 after subtracting 312 from 354.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 78

Advancing to step 5:
If we divide 424 by 78, we get 5 and a remainder of 34.
The next digit of our result is 5. 
Result so far: 745.0
Subtract 390 from 424 to get 34.
Bring next digit (9) of the dividend behind the 34 and repeat the process: 349 / 78

On to step 6:
349 divided by 78 is 4 with a remainder of 37.
The number 4 becomes the next digit in our result. 
Result so far: 7454.0
Deduct 312 from 349 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 7:
If we divide 370 by 78, we get 4 and a remainder of 58.
Put 4 as the next digit of the answer. 
Result so far: 7454.4
Deduct 312 from 370 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 8:
If we divide 580 by 78, we get 7 and a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7454.47
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.

Advancing to step 9:
78 goes into 340 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 7454.474
The remainder is 28 after subtracting 312 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 10:
If we divide 280 by 78, we get 3 and a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 7454.4743
Deduct 234 from 280 and we're left 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.

Advancing to step 11:
460 divided by 78 is 5 with a remainder of 70.
The number 5 becomes the next digit in our result. 
Result so far: 7454.47435
The remainder is 70 after subtracting 390 from 460.
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 12:
78 goes into 700 8 times with a remainder of 76.
Write down 8 as next digit of the result. 
Result so far: 7454.474358
Subtracting 624 from 700 leaves us 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.

Moving on to step 13:
78 goes into 760 9 times with a remainder of 58.
The next digit of our result is 9. 
Result so far: 7454.4743589
The remainder is 58 after subtracting 702 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 14:
78 can be fit into 580 7 times, resulting in a remainder of 34.
Use 7 as the next digit of our solution. 
Result so far: 7454.47435897
Subtracting 546 from 580 leaves us 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.

The final result is 7454.47435897 with a remainder of 3.4e-08.
