26390504 divided by 578 
We want to figure out the number of times 26390504 can be divided by 578.

Moving on to step 1:
2 divided by 578 is 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 578

Going ahead to step 2:
The number 578 fits into 26 0 times, leaving a remainder of 26.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 26, we end up with 26.
Bring next digit (3) of the dividend behind the 26 and repeat the process: 263 / 578

Going ahead to step 3:
578 can be fit into 263 0 times, resulting in a remainder of 263.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 263, we end up with 263.
Append the next digit (9) from the dividend to 263 and continue with: 2639 / 578

Let's proceed to step 4:
2639 divided by 578 is 4 with a remainder of 327.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 2312 away from 2639, we end up with 327.
Append the next digit (0) from the dividend to 327 and continue with: 3270 / 578

Moving on to step 5:
The number 578 fits into 3270 5 times, leaving a remainder of 380.
The next digit of our result is 5. 
Result so far: 45.0
If we take 2890 away from 3270, we end up with 380.
Take the next digit (5) from the dividend and append it to 380, then repeat: 3805 / 578

Moving on to step 6:
578 can be fit into 3805 6 times, resulting in a remainder of 337.
The next digit of our result is 6. 
Result so far: 456.0
Deduct 3468 from 3805 and we're left with 337.
Append the next digit (0) from the dividend to 337 and continue with: 3370 / 578

Advancing to step 7:
578 goes into 3370 5 times with a remainder of 480.
Record the quotient 5 as the next digit in the result. 
Result so far: 4565.0
Subtract 2890 from 3370 to get 480.
Take the next digit (4) from the dividend and append it to 480, then repeat: 4804 / 578

Moving on to step 8:
If we divide 4804 by 578, we get 8 and a remainder of 180.
Write down 8 as next digit of the result. 
Result so far: 45658.0
If we subtract 4624 from 4804, we get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Step 9:
578 goes into 1800 3 times with a remainder of 66.
Write down 3 as next digit of the result. 
Result so far: 45658.3
The remainder is 66 after subtracting 1734 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 10:
The number 578 fits into 660 1 times, leaving a remainder of 82.
The next digit of our result is 1. 
Result so far: 45658.31
Subtracting 578 from 660 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 11:
578 can be fit into 820 1 times, resulting in a remainder of 242.
Write down 1 as next digit of the result. 
Result so far: 45658.311
Deduct 578 from 820 and we're left with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

The final outcome is 45658.311, with a leftover of 0.0242.
