Let's divide 25085014 by 661
We want to divide 25085014 by 661.

Advancing to step 1:
If we divide 2 by 661, we get 0 and 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 / 661

Let's proceed to step 2:
661 can be fit into 25 0 times, resulting in a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 661

On to step 3:
661 goes into 250 0 times with a remainder of 250.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 250 after subtracting 0 from 250.
Bring next digit (8) of the dividend behind the 250 and repeat the process: 2508 / 661

On to step 4:
If we divide 2508 by 661, we get 3 and a remainder of 525.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 1983 away from 2508, we end up with 525.
Append the next digit (5) from the dividend to 525 and continue with: 5255 / 661

Advancing to step 5:
661 can be fit into 5255 7 times, resulting in a remainder of 628.
Use 7 as the next digit of our solution. 
Result so far: 37.0
If we take 4627 away from 5255, we end up with 628.
Take the next digit (0) from the dividend and append it to 628, then repeat: 6280 / 661

Moving on to step 6:
The number 661 fits into 6280 9 times, leaving a remainder of 331.
Use 9 as the next digit of our solution. 
Result so far: 379.0
Subtract 5949 from 6280 to get 331.
Bring next digit (1) of the dividend behind the 331 and repeat the process: 3311 / 661

Advancing to step 7:
661 can be fit into 3311 5 times, resulting in a remainder of 6.
The next digit of our result is 5. 
Result so far: 3795.0
Subtract 3305 from 3311 to get 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 661

Let's proceed to step 8:
661 goes into 64 0 times with a remainder of 64.
Put 0 as the next digit of the answer. 
Result so far: 37950.0
Subtracting 0 from 64 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 9:
When dividing 640 by 661, we get 0 with a remainder of 640.
Record the quotient 0 as the next digit in the result. 
Result so far: 37950.0
Deduct 0 from 640 and we're left with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Going ahead to step 10:
If we divide 6400 by 661, we get 9 and a remainder of 451.
The next digit of our result is 9. 
Result so far: 37950.09
If we subtract 5949 from 6400, we get 451.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4510, and continue the process.

Moving on to step 11:
The number 661 fits into 4510 6 times, leaving a remainder of 544.
Put 6 as the next digit of the answer. 
Result so far: 37950.096
If we subtract 3966 from 4510, we get 544.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Moving on to step 12:
661 goes into 5440 8 times with a remainder of 152.
The next digit of our result is 8. 
Result so far: 37950.0968
If we subtract 5288 from 5440, we get 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 13:
661 goes into 1520 2 times with a remainder of 198.
Use 2 as the next digit of our solution. 
Result so far: 37950.09682
Subtract 1322 from 1520 to 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.

Moving on to step 14:
1980 divided by 661 is 2 with a remainder of 658.
Put 2 as the next digit of the answer. 
Result so far: 37950.096822
Deduct 1322 from 1980 and we're left with 658.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6580, and continue the process.

The quotient of the division is 37950.096822, and the remainder is 6.58e-05.
