We look at the division of 78581824 by 525 
We want to divide 78581824 by 525.

Going ahead to step 1:
If we divide 7 by 525, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 525

Let's proceed to step 2:
78 divided by 525 is 0 with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Include the next digit (5) from the dividend after 78, then repeat: 785 / 525

Moving on to step 3:
525 goes into 785 1 times with a remainder of 260.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 260 after subtracting 525 from 785.
Append the next digit (8) from the dividend to 260 and continue with: 2608 / 525

Let's proceed to step 4:
525 can be fit into 2608 4 times, resulting in a remainder of 508.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
The remainder is 508 after subtracting 2100 from 2608.
Append the next digit (1) from the dividend to 508 and continue with: 5081 / 525

Step 5:
When dividing 5081 by 525, we get 9 with a remainder of 356.
The next digit of our result is 9. 
Result so far: 149.0
Subtracting 4725 from 5081 leaves us with 356.
Include the next digit (8) from the dividend after 356, then repeat: 3568 / 525

Advancing to step 6:
525 can be fit into 3568 6 times, resulting in a remainder of 418.
Use 6 as the next digit of our solution. 
Result so far: 1496.0
Deduct 3150 from 3568 and we're left with 418.
Append the next digit (2) from the dividend to 418 and continue with: 4182 / 525

Advancing to step 7:
If we divide 4182 by 525, we get 7 and a remainder of 507.
Use 7 as the next digit of our solution. 
Result so far: 14967.0
If we take 3675 away from 4182, we end up with 507.
Grab the next digit (4) from the dividend, add it to 507, then carry on: 5074 / 525

On to step 8:
When dividing 5074 by 525, we get 9 with a remainder of 349.
Write down 9 as next digit of the result. 
Result so far: 149679.0
Subtract 4725 from 5074 to get 349.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

Advancing to step 9:
525 goes into 3490 6 times with a remainder of 340.
Put 6 as the next digit of the answer. 
Result so far: 149679.6
The remainder is 340 after subtracting 3150 from 3490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

Let's proceed to step 10:
3400 divided by 525 is 6 with a remainder of 250.
Write down 6 as next digit of the result. 
Result so far: 149679.66
If we subtract 3150 from 3400, we get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

The final outcome is 149679.66, with a leftover of 0.25.
