25156131 ÷ 649 
We want to divide 25156131 by 649.

Moving on to step 1:
649 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 649

Let's proceed to step 2:
If we divide 25 by 649, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (1) of the dividend behind the 25 and repeat the process: 251 / 649

Step 3:
649 goes into 251 0 times with a remainder of 251.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 251 leaves us with 251.
Append the next digit (5) from the dividend to 251 and continue with: 2515 / 649

Let's proceed to step 4:
When dividing 2515 by 649, we get 3 with a remainder of 568.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 1947 from 2515, we get 568.
Bring next digit (6) of the dividend behind the 568 and repeat the process: 5686 / 649

Step 5:
The number 649 fits into 5686 8 times, leaving a remainder of 494.
The next digit of our result is 8. 
Result so far: 38.0
Subtract 5192 from 5686 to get 494.
Bring next digit (1) of the dividend behind the 494 and repeat the process: 4941 / 649

Step 6:
649 can be fit into 4941 7 times, resulting in a remainder of 398.
The number 7 becomes the next digit in our result. 
Result so far: 387.0
Deduct 4543 from 4941 and we're left with 398.
Grab the next digit (3) from the dividend, add it to 398, then carry on: 3983 / 649

On to step 7:
649 goes into 3983 6 times with a remainder of 89.
Put 6 as the next digit of the answer. 
Result so far: 3876.0
The remainder is 89 after subtracting 3894 from 3983.
Bring next digit (1) of the dividend behind the 89 and repeat the process: 891 / 649

Let's proceed to step 8:
891 divided by 649 is 1 with a remainder of 242.
The number 1 becomes the next digit in our result. 
Result so far: 38761.0
If we take 649 away from 891, we end up with 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Let's proceed to step 9:
The number 649 fits into 2420 3 times, leaving a remainder of 473.
Record the quotient 3 as the next digit in the result. 
Result so far: 38761.3
Subtract 1947 from 2420 to get 473.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4730, and continue the process.

Going ahead to step 10:
4730 divided by 649 is 7 with a remainder of 187.
Record the quotient 7 as the next digit in the result. 
Result so far: 38761.37
If we subtract 4543 from 4730, we get 187.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1870, and continue the process.

On to step 11:
649 goes into 1870 2 times with a remainder of 572.
Put 2 as the next digit of the answer. 
Result so far: 38761.372
If we take 1298 away from 1870, we end up with 572.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5720, and continue the process.

Moving on to step 12:
When dividing 5720 by 649, we get 8 with a remainder of 528.
Write down 8 as next digit of the result. 
Result so far: 38761.3728
If we subtract 5192 from 5720, we get 528.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

Moving on to step 13:
649 can be fit into 5280 8 times, resulting in a remainder of 88.
Use 8 as the next digit of our solution. 
Result so far: 38761.37288
The remainder is 88 after subtracting 5192 from 5280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

The final result is 38761.37288 with a remainder of 8.8e-05.
