We divide 2590087 by 578
We want to divide 2590087 by 578.

Step 1:
578 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 578

Step 2:
25 divided by 578 is 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (9) from the dividend, attach it to 25 and continue: 259 / 578

Moving on to step 3:
If we divide 259 by 578, we get 0 and a remainder of 259.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 259 after subtracting 0 from 259.
Fetch the next digit (0) from the dividend, attach it to 259 and continue: 2590 / 578

On to step 4:
578 goes into 2590 4 times with a remainder of 278.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we subtract 2312 from 2590, we get 278.
Fetch the next digit (0) from the dividend, attach it to 278 and continue: 2780 / 578

Let's proceed to step 5:
If we divide 2780 by 578, we get 4 and a remainder of 468.
The number 4 becomes the next digit in our result. 
Result so far: 44.0
If we subtract 2312 from 2780, we get 468.
Grab the next digit (8) from the dividend, add it to 468, then carry on: 4688 / 578

Moving on to step 6:
If we divide 4688 by 578, we get 8 and a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 448.0
If we subtract 4624 from 4688, we get 64.
Fetch the next digit (7) from the dividend, attach it to 64 and continue: 647 / 578

Moving on to step 7:
If we divide 647 by 578, we get 1 and a remainder of 69.
Use 1 as the next digit of our solution. 
Result so far: 4481.0
Subtract 578 from 647 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Going ahead to step 8:
If we divide 690 by 578, we get 1 and a remainder of 112.
Put 1 as the next digit of the answer. 
Result so far: 4481.1
If we subtract 578 from 690, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Going ahead to step 9:
The number 578 fits into 1120 1 times, leaving a remainder of 542.
Record the quotient 1 as the next digit in the result. 
Result so far: 4481.11
If we take 578 away from 1120, we end up with 542.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5420, and continue the process.

The final outcome is 4481.11, with a leftover of 0.542.
