25290488 ÷ 42 
Let's see how many times 42 fits into 25290488.

Let's proceed to step 1:
2 divided by 42 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 42

Going ahead to step 2:
If we divide 25 by 42, we get 0 and a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 42

Going ahead to step 3:
The number 42 fits into 252 6 times, leaving a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 252 away from 252, we end up with 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 42

Moving on to step 4:
42 can be fit into 9 0 times, resulting in a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 60.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (0) of the dividend behind the 9 and repeat the process: 90 / 42

Step 5:
42 goes into 90 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 602.0
If we subtract 84 from 90, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 42

Advancing to step 6:
If we divide 64 by 42, we get 1 and a remainder of 22.
Use 1 as the next digit of our solution. 
Result so far: 6021.0
The remainder is 22 after subtracting 42 from 64.
Append the next digit (8) from the dividend to 22 and continue with: 228 / 42

Step 7:
When dividing 228 by 42, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 60215.0
If we take 210 away from 228, we end up with 18.
Include the next digit (8) from the dividend after 18, then repeat: 188 / 42

Let's proceed to step 8:
When dividing 188 by 42, we get 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 602154.0
If we take 168 away from 188, 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 9:
When dividing 200 by 42, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 602154.4
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 10:
If we divide 320 by 42, we get 7 and a remainder of 26.
Write down 7 as next digit of the result. 
Result so far: 602154.47
Deduct 294 from 320 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 11:
260 divided by 42 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 602154.476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 12:
When dividing 80 by 42, we get 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 602154.4761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 602154.47619
If we subtract 378 from 380, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 14:
20 divided by 42 is 0 with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 602154.47619
Subtracting 0 from 20 leaves us 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.

Going ahead to step 15:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 602154.4761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 16:
42 goes into 320 7 times with a remainder of 26.
Use 7 as the next digit of our solution. 
Result so far: 602154.47619047
The remainder is 26 after subtracting 294 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 602154.47619047 with a remainder of 2.6e-08.
