25596804 divided by 42 
We want to divide 25596804 by 42.

Step 1:
The number 42 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 42

Going ahead to step 2:
When dividing 25 by 42, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (5) from the dividend after 25, then repeat: 255 / 42

Let's proceed to step 3:
42 goes into 255 6 times with a remainder of 3.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtracting 252 from 255 leaves us with 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 42

Moving on to step 4:
If we divide 39 by 42, we get 0 and a remainder of 39.
Write down 0 as next digit of the result. 
Result so far: 60.0
Subtract 0 from 39 to get 39.
Fetch the next digit (6) from the dividend, attach it to 39 and continue: 396 / 42

On to step 5:
When dividing 396 by 42, we get 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 609.0
Subtracting 378 from 396 leaves us with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 42

Step 6:
42 goes into 188 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 6094.0
If we take 168 away from 188, we end up with 20.
Bring next digit (0) of the dividend behind the 20 and repeat the process: 200 / 42

Step 7:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 60944.0
Deduct 168 from 200 and we're left with 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 42

Advancing to step 8:
324 divided by 42 is 7 with a remainder of 30.
The number 7 becomes the next digit in our result. 
Result so far: 609447.0
If we take 294 away from 324, 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 9:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The next digit of our result is 7. 
Result so far: 609447.7
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
60 divided by 42 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 609447.71
If we take 42 away from 60, 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.

Going ahead to step 11:
180 divided by 42 is 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 609447.714
Deduct 168 from 180 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 12:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 609447.7142
The remainder is 36 after subtracting 84 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 13:
When dividing 360 by 42, we get 8 with a remainder of 24.
Use 8 as the next digit of our solution. 
Result so far: 609447.71428
Subtracting 336 from 360 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
If we divide 240 by 42, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 609447.714285
Subtracting 210 from 240 leaves us 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.

Going ahead to step 15:
If we divide 300 by 42, we get 7 and a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 609447.7142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 16:
60 divided by 42 is 1 with a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 609447.71428571
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

After the division, we end up with 609447.71428571 and a remainder of 1.8e-08.
