255898 ÷ 40 
We're looking to find how many times 40 goes into 255898.

Let's proceed to step 1:
The number 40 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 40

Moving on to step 2:
When dividing 25 by 40, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (5) from the dividend to 25 and continue with: 255 / 40

Moving on to step 3:
The number 40 fits into 255 6 times, leaving a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 240 from 255 to get 15.
Include the next digit (8) from the dividend after 15, then repeat: 158 / 40

Advancing to step 4:
158 divided by 40 is 3 with a remainder of 38.
Record the quotient 3 as the next digit in the result. 
Result so far: 63.0
Subtracting 120 from 158 leaves us with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 40

Moving on to step 5:
389 divided by 40 is 9 with a remainder of 29.
The next digit of our result is 9. 
Result so far: 639.0
Subtract 360 from 389 to get 29.
Include the next digit (8) from the dividend after 29, then repeat: 298 / 40

Let's proceed to step 6:
298 divided by 40 is 7 with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 6397.0
If we take 280 away from 298, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
40 goes into 180 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 6397.4
If we take 160 away from 180, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
40 can be fit into 200 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6397.45
Deduct 200 from 200 and we're left with 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 9:
40 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6397.45
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 10:
0 divided by 40 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 6397.45
If we take 0 away from 0, we end up with 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 quotient of the division is 6397.45, and the remainder is 0.0.
