We divide 25942 by 40
We want to figure out the number of times 25942 can be divided by 40.

Going ahead to step 1:
2 divided by 40 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 40

Step 2:
The number 40 fits into 25 0 times, leaving a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Append the next digit (9) from the dividend to 25 and continue with: 259 / 40

Moving on to step 3:
When dividing 259 by 40, we get 6 with a remainder of 19.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 19 after subtracting 240 from 259.
Fetch the next digit (4) from the dividend, attach it to 19 and continue: 194 / 40

On to step 4:
40 goes into 194 4 times with a remainder of 34.
Write down 4 as next digit of the result. 
Result so far: 64.0
Deduct 160 from 194 and we're left with 34.
Fetch the next digit (2) from the dividend, attach it to 34 and continue: 342 / 40

Advancing to step 5:
342 divided by 40 is 8 with a remainder of 22.
The next digit of our result is 8. 
Result so far: 648.0
Deduct 320 from 342 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 6:
When dividing 220 by 40, we get 5 with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 648.5
If we subtract 200 from 220, 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.

Step 7:
40 can be fit into 200 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 648.55
Subtracting 200 from 200 leaves us 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.

In conclusion, the division gives 648.55 with a balance of 0.0.
