25977986 divided by 408 
Our goal is to divide 25977986 by 408.

Step 1:
408 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 408

Moving on to step 2:
The number 408 fits into 25 0 times, leaving 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 (9) from the dividend after 25, then repeat: 259 / 408

Advancing to step 3:
259 divided by 408 is 0 with a remainder of 259.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 259, we get 259.
Grab the next digit (7) from the dividend, add it to 259, then carry on: 2597 / 408

Moving on to step 4:
408 goes into 2597 6 times with a remainder of 149.
The next digit of our result is 6. 
Result so far: 6.0
If we take 2448 away from 2597, we end up with 149.
Include the next digit (7) from the dividend after 149, then repeat: 1497 / 408

Let's proceed to step 5:
The number 408 fits into 1497 3 times, leaving a remainder of 273.
The number 3 becomes the next digit in our result. 
Result so far: 63.0
Subtracting 1224 from 1497 leaves us with 273.
Take the next digit (9) from the dividend and append it to 273, then repeat: 2739 / 408

Advancing to step 6:
408 can be fit into 2739 6 times, resulting in a remainder of 291.
Write down 6 as next digit of the result. 
Result so far: 636.0
Subtract 2448 from 2739 to get 291.
Append the next digit (8) from the dividend to 291 and continue with: 2918 / 408

Let's proceed to step 7:
408 goes into 2918 7 times with a remainder of 62.
The next digit of our result is 7. 
Result so far: 6367.0
If we take 2856 away from 2918, we end up with 62.
Bring next digit (6) of the dividend behind the 62 and repeat the process: 626 / 408

Let's proceed to step 8:
626 divided by 408 is 1 with a remainder of 218.
Record the quotient 1 as the next digit in the result. 
Result so far: 63671.0
The remainder is 218 after subtracting 408 from 626.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Advancing to step 9:
The number 408 fits into 2180 5 times, leaving a remainder of 140.
The next digit of our result is 5. 
Result so far: 63671.5
The remainder is 140 after subtracting 2040 from 2180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

Going ahead to step 10:
1400 divided by 408 is 3 with a remainder of 176.
The next digit of our result is 3. 
Result so far: 63671.53
If we subtract 1224 from 1400, we get 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Let's proceed to step 11:
The number 408 fits into 1760 4 times, leaving a remainder of 128.
Use 4 as the next digit of our solution. 
Result so far: 63671.534
If we subtract 1632 from 1760, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Moving on to step 12:
When dividing 1280 by 408, we get 3 with a remainder of 56.
The number 3 becomes the next digit in our result. 
Result so far: 63671.5343
Subtract 1224 from 1280 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 13:
408 goes into 560 1 times with a remainder of 152.
Record the quotient 1 as the next digit in the result. 
Result so far: 63671.53431
Deduct 408 from 560 and we're left with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Advancing to step 14:
If we divide 1520 by 408, we get 3 and a remainder of 296.
Record the quotient 3 as the next digit in the result. 
Result so far: 63671.534313
If we subtract 1224 from 1520, we get 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Going ahead to step 15:
The number 408 fits into 2960 7 times, leaving a remainder of 104.
Write down 7 as next digit of the result. 
Result so far: 63671.5343137
Subtracting 2856 from 2960 leaves us with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Let's proceed to step 16:
408 goes into 1040 2 times with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 63671.53431372
If we subtract 816 from 1040, we get 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

The final outcome is 63671.53431372, with a leftover of 2.24e-07.
