Let's divide 15087865 by 578
Let's see how many times 578 fits into 15087865.

On to step 1:
If we divide 1 by 578, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 578

On to step 2:
The number 578 fits into 15 0 times, leaving a remainder of 15.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Take the next digit (0) from the dividend and append it to 15, then repeat: 150 / 578

Step 3:
150 divided by 578 is 0 with a remainder of 150.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 150 after subtracting 0 from 150.
Fetch the next digit (8) from the dividend, attach it to 150 and continue: 1508 / 578

On to step 4:
578 goes into 1508 2 times with a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 1156 from 1508, we get 352.
Take the next digit (7) from the dividend and append it to 352, then repeat: 3527 / 578

Let's proceed to step 5:
578 can be fit into 3527 6 times, resulting in a remainder of 59.
Record the quotient 6 as the next digit in the result. 
Result so far: 26.0
Subtract 3468 from 3527 to get 59.
Include the next digit (8) from the dividend after 59, then repeat: 598 / 578

On to step 6:
If we divide 598 by 578, we get 1 and a remainder of 20.
The next digit of our result is 1. 
Result so far: 261.0
If we subtract 578 from 598, we get 20.
Fetch the next digit (6) from the dividend, attach it to 20 and continue: 206 / 578

Let's proceed to step 7:
When dividing 206 by 578, we get 0 with a remainder of 206.
The number 0 becomes the next digit in our result. 
Result so far: 2610.0
If we take 0 away from 206, we end up with 206.
Take the next digit (5) from the dividend and append it to 206, then repeat: 2065 / 578

On to step 8:
The number 578 fits into 2065 3 times, leaving a remainder of 331.
The next digit of our result is 3. 
Result so far: 26103.0
Deduct 1734 from 2065 and we're left with 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Let's proceed to step 9:
578 goes into 3310 5 times with a remainder of 420.
Use 5 as the next digit of our solution. 
Result so far: 26103.5
Deduct 2890 from 3310 and we're left with 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4200, and continue the process.

Going ahead to step 10:
578 can be fit into 4200 7 times, resulting in a remainder of 154.
Put 7 as the next digit of the answer. 
Result so far: 26103.57
If we take 4046 away from 4200, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

Going ahead to step 11:
578 goes into 1540 2 times with a remainder of 384.
The next digit of our result is 2. 
Result so far: 26103.572
Deduct 1156 from 1540 and we're left with 384.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Let's proceed to step 12:
578 can be fit into 3840 6 times, resulting in a remainder of 372.
The next digit of our result is 6. 
Result so far: 26103.5726
Subtracting 3468 from 3840 leaves us with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

Let's proceed to step 13:
The number 578 fits into 3720 6 times, leaving a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 26103.57266
Subtracting 3468 from 3720 leaves us with 252.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

The final result is 26103.57266 with a remainder of 0.000252.
