25150877 divided by 649 
Let's see how many times 649 fits into 25150877.

Going ahead to step 1:
When dividing 2 by 649, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 649

Let's proceed to step 2:
If we divide 25 by 649, we get 0 and a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Take the next digit (1) from the dividend and append it to 25, then repeat: 251 / 649

Advancing to step 3:
When dividing 251 by 649, we get 0 with a remainder of 251.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 251 and we're left with 251.
Fetch the next digit (5) from the dividend, attach it to 251 and continue: 2515 / 649

Moving on to step 4:
The number 649 fits into 2515 3 times, leaving 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.
Take the next digit (0) from the dividend and append it to 568, then repeat: 5680 / 649

Moving on to step 5:
649 can be fit into 5680 8 times, resulting in a remainder of 488.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we take 5192 away from 5680, we end up with 488.
Grab the next digit (8) from the dividend, add it to 488, then carry on: 4888 / 649

On to step 6:
When dividing 4888 by 649, we get 7 with a remainder of 345.
Put 7 as the next digit of the answer. 
Result so far: 387.0
Deduct 4543 from 4888 and we're left with 345.
Include the next digit (7) from the dividend after 345, then repeat: 3457 / 649

Let's proceed to step 7:
If we divide 3457 by 649, we get 5 and a remainder of 212.
Record the quotient 5 as the next digit in the result. 
Result so far: 3875.0
If we take 3245 away from 3457, we end up with 212.
Append the next digit (7) from the dividend to 212 and continue with: 2127 / 649

Moving on to step 8:
649 can be fit into 2127 3 times, resulting in a remainder of 180.
The number 3 becomes the next digit in our result. 
Result so far: 38753.0
If we take 1947 away from 2127, we end up with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Let's proceed to step 9:
649 goes into 1800 2 times with a remainder of 502.
Put 2 as the next digit of the answer. 
Result so far: 38753.2
If we take 1298 away from 1800, we end up with 502.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5020, and continue the process.

Moving on to step 10:
The number 649 fits into 5020 7 times, leaving a remainder of 477.
Put 7 as the next digit of the answer. 
Result so far: 38753.27
Subtract 4543 from 5020 to get 477.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4770, and continue the process.

Going ahead to step 11:
649 goes into 4770 7 times with a remainder of 227.
The number 7 becomes the next digit in our result. 
Result so far: 38753.277
The remainder is 227 after subtracting 4543 from 4770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

After the division, we end up with 38753.277 and a remainder of 0.0227.
