We're dividing 25803531 by 408 
We want to divide 25803531 by 408.

Going ahead to step 1:
2 divided by 408 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 408

Going ahead to step 2:
If we divide 25 by 408, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 408

Moving on to step 3:
408 goes into 258 0 times with a remainder of 258.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 258, we get 258.
Append the next digit (0) from the dividend to 258 and continue with: 2580 / 408

Going ahead to step 4:
2580 divided by 408 is 6 with a remainder of 132.
Put 6 as the next digit of the answer. 
Result so far: 6.0
The remainder is 132 after subtracting 2448 from 2580.
Grab the next digit (3) from the dividend, add it to 132, then carry on: 1323 / 408

Moving on to step 5:
When dividing 1323 by 408, we get 3 with a remainder of 99.
The next digit of our result is 3. 
Result so far: 63.0
Subtract 1224 from 1323 to get 99.
Take the next digit (5) from the dividend and append it to 99, then repeat: 995 / 408

Advancing to step 6:
408 can be fit into 995 2 times, resulting in a remainder of 179.
Put 2 as the next digit of the answer. 
Result so far: 632.0
Subtract 816 from 995 to get 179.
Bring next digit (3) of the dividend behind the 179 and repeat the process: 1793 / 408

Let's proceed to step 7:
When dividing 1793 by 408, we get 4 with a remainder of 161.
The next digit of our result is 4. 
Result so far: 6324.0
Subtracting 1632 from 1793 leaves us with 161.
Append the next digit (1) from the dividend to 161 and continue with: 1611 / 408

Moving on to step 8:
When dividing 1611 by 408, we get 3 with a remainder of 387.
The next digit of our result is 3. 
Result so far: 63243.0
If we take 1224 away from 1611, we end up with 387.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3870, and continue the process.

Let's proceed to step 9:
The number 408 fits into 3870 9 times, leaving a remainder of 198.
Record the quotient 9 as the next digit in the result. 
Result so far: 63243.9
If we subtract 3672 from 3870, we get 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 10:
408 goes into 1980 4 times with a remainder of 348.
Use 4 as the next digit of our solution. 
Result so far: 63243.94
If we subtract 1632 from 1980, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

Step 11:
3480 divided by 408 is 8 with a remainder of 216.
The next digit of our result is 8. 
Result so far: 63243.948
Subtract 3264 from 3480 to get 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Going ahead to step 12:
2160 divided by 408 is 5 with a remainder of 120.
Use 5 as the next digit of our solution. 
Result so far: 63243.9485
The remainder is 120 after subtracting 2040 from 2160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 13:
The number 408 fits into 1200 2 times, leaving a remainder of 384.
The number 2 becomes the next digit in our result. 
Result so far: 63243.94852
The remainder is 384 after subtracting 816 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3840, and continue the process.

Step 14:
When dividing 3840 by 408, we get 9 with a remainder of 168.
The next digit of our result is 9. 
Result so far: 63243.948529
If we subtract 3672 from 3840, we get 168.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1680, and continue the process.

Going ahead to step 15:
If we divide 1680 by 408, we get 4 and a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 63243.9485294
If we take 1632 away from 1680, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 16:
408 goes into 480 1 times with a remainder of 72.
The number 1 becomes the next digit in our result. 
Result so far: 63243.94852941
Subtracting 408 from 480 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Our division results in 63243.94852941 with a remaining 7.2e-08.
