19972525 divided by 665 
Our goal is to divide 19972525 by 665.

Going ahead to step 1:
If we divide 1 by 665, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 665

On to step 2:
665 can be fit into 19 0 times, resulting in a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (9) from the dividend after 19, then repeat: 199 / 665

On to step 3:
665 can be fit into 199 0 times, resulting in a remainder of 199.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 199, we get 199.
Fetch the next digit (7) from the dividend, attach it to 199 and continue: 1997 / 665

Let's proceed to step 4:
1997 divided by 665 is 3 with a remainder of 2.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Subtract 1995 from 1997 to get 2.
Append the next digit (2) from the dividend to 2 and continue with: 22 / 665

On to step 5:
665 goes into 22 0 times with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 30.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (5) from the dividend, attach it to 22 and continue: 225 / 665

Going ahead to step 6:
225 divided by 665 is 0 with a remainder of 225.
Write down 0 as next digit of the result. 
Result so far: 300.0
Subtract 0 from 225 to get 225.
Bring next digit (2) of the dividend behind the 225 and repeat the process: 2252 / 665

Moving on to step 7:
2252 divided by 665 is 3 with a remainder of 257.
Put 3 as the next digit of the answer. 
Result so far: 3003.0
Subtract 1995 from 2252 to get 257.
Grab the next digit (5) from the dividend, add it to 257, then carry on: 2575 / 665

Step 8:
If we divide 2575 by 665, we get 3 and a remainder of 580.
Record the quotient 3 as the next digit in the result. 
Result so far: 30033.0
Subtract 1995 from 2575 to get 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5800, and continue the process.

Step 9:
If we divide 5800 by 665, we get 8 and a remainder of 480.
The number 8 becomes the next digit in our result. 
Result so far: 30033.8
Subtract 5320 from 5800 to get 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

On to step 10:
665 can be fit into 4800 7 times, resulting in a remainder of 145.
Use 7 as the next digit of our solution. 
Result so far: 30033.87
If we take 4655 away from 4800, we end up with 145.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1450, and continue the process.

Advancing to step 11:
665 goes into 1450 2 times with a remainder of 120.
The next digit of our result is 2. 
Result so far: 30033.872
If we subtract 1330 from 1450, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Going ahead to step 12:
1200 divided by 665 is 1 with a remainder of 535.
Use 1 as the next digit of our solution. 
Result so far: 30033.8721
If we subtract 665 from 1200, we get 535.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5350, and continue the process.

Advancing to step 13:
If we divide 5350 by 665, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 30033.87218
If we take 5320 away from 5350, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
300 divided by 665 is 0 with a remainder of 300.
Put 0 as the next digit of the answer. 
Result so far: 30033.87218
If we take 0 away from 300, we end up with 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 15:
665 can be fit into 3000 4 times, resulting in a remainder of 340.
The next digit of our result is 4. 
Result so far: 30033.8721804
If we take 2660 away from 3000, we end up with 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3400, and continue the process.

On to step 16:
When dividing 3400 by 665, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 30033.87218045
Subtracting 3325 from 3400 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

After the division, we end up with 30033.87218045 and a remainder of 7.5e-08.
