We're dividing 259315 by 40 
We want to divide 259315 by 40.

Moving on to step 1:
40 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 40

On to step 2:
If we divide 25 by 40, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 40

Moving on to step 3:
259 divided by 40 is 6 with a remainder of 19.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 240 away from 259, we end up with 19.
Bring next digit (3) of the dividend behind the 19 and repeat the process: 193 / 40

Step 4:
The number 40 fits into 193 4 times, leaving a remainder of 33.
The next digit of our result is 4. 
Result so far: 64.0
Subtracting 160 from 193 leaves us with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 40

On to step 5:
331 divided by 40 is 8 with a remainder of 11.
The number 8 becomes the next digit in our result. 
Result so far: 648.0
If we subtract 320 from 331, we get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 40

Let's proceed to step 6:
The number 40 fits into 115 2 times, leaving a remainder of 35.
Use 2 as the next digit of our solution. 
Result so far: 6482.0
The remainder is 35 after subtracting 80 from 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 7:
The number 40 fits into 350 8 times, leaving a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 6482.8
If we take 320 away from 350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 40 is 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 6482.87
If we subtract 280 from 300, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
If we divide 200 by 40, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 6482.875
If we subtract 200 from 200, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 40 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6482.875
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
If we divide 0 by 40, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6482.875
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 6482.875, with a leftover of 0.0.
