We look at the division of 25244939 by 663 
We want to figure out the number of times 25244939 can be divided by 663.

Let's proceed to step 1:
663 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 663

Let's proceed to step 2:
663 can be fit into 25 0 times, resulting in a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (2) from the dividend, attach it to 25 and continue: 252 / 663

Let's proceed to step 3:
663 goes into 252 0 times with a remainder of 252.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 252 and we're left with 252.
Append the next digit (4) from the dividend to 252 and continue with: 2524 / 663

Going ahead to step 4:
When dividing 2524 by 663, we get 3 with a remainder of 535.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 1989 from 2524 and we're left with 535.
Append the next digit (4) from the dividend to 535 and continue with: 5354 / 663

Moving on to step 5:
The number 663 fits into 5354 8 times, leaving a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 38.0
If we subtract 5304 from 5354, we get 50.
Fetch the next digit (9) from the dividend, attach it to 50 and continue: 509 / 663

Going ahead to step 6:
If we divide 509 by 663, we get 0 and a remainder of 509.
Use 0 as the next digit of our solution. 
Result so far: 380.0
If we take 0 away from 509, we end up with 509.
Grab the next digit (3) from the dividend, add it to 509, then carry on: 5093 / 663

Moving on to step 7:
663 goes into 5093 7 times with a remainder of 452.
Use 7 as the next digit of our solution. 
Result so far: 3807.0
Subtracting 4641 from 5093 leaves us with 452.
Include the next digit (9) from the dividend after 452, then repeat: 4529 / 663

Going ahead to step 8:
663 goes into 4529 6 times with a remainder of 551.
Use 6 as the next digit of our solution. 
Result so far: 38076.0
The remainder is 551 after subtracting 3978 from 4529.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5510, and continue the process.

Step 9:
The number 663 fits into 5510 8 times, leaving a remainder of 206.
Use 8 as the next digit of our solution. 
Result so far: 38076.8
Subtracting 5304 from 5510 leaves us with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Moving on to step 10:
663 goes into 2060 3 times with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 38076.83
If we take 1989 away from 2060, we end up with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 11:
710 divided by 663 is 1 with a remainder of 47.
Put 1 as the next digit of the answer. 
Result so far: 38076.831
Subtract 663 from 710 to get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 12:
When dividing 470 by 663, we get 0 with a remainder of 470.
The number 0 becomes the next digit in our result. 
Result so far: 38076.831
Subtracting 0 from 470 leaves us with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Going ahead to step 13:
If we divide 4700 by 663, we get 7 and a remainder of 59.
Write down 7 as next digit of the result. 
Result so far: 38076.83107
Subtract 4641 from 4700 to get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Moving on to step 14:
663 goes into 590 0 times with a remainder of 590.
Put 0 as the next digit of the answer. 
Result so far: 38076.83107
If we subtract 0 from 590, we get 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5900, and continue the process.

Moving on to step 15:
The number 663 fits into 5900 8 times, leaving a remainder of 596.
The next digit of our result is 8. 
Result so far: 38076.8310708
Subtracting 5304 from 5900 leaves us with 596.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5960, and continue the process.

Let's proceed to step 16:
663 goes into 5960 8 times with a remainder of 656.
Put 8 as the next digit of the answer. 
Result so far: 38076.83107088
Deduct 5304 from 5960 and we're left with 656.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6560, and continue the process.

The final outcome is 38076.83107088, with a leftover of 6.56e-07.
