1663437 divided by 504 
Let's see how many times 504 fits into 1663437.

Going ahead to step 1:
If we divide 1 by 504, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 504

Moving on to step 2:
16 divided by 504 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 16 and we're left with 16.
Fetch the next digit (6) from the dividend, attach it to 16 and continue: 166 / 504

Step 3:
When dividing 166 by 504, we get 0 with a remainder of 166.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 166 to get 166.
Include the next digit (3) from the dividend after 166, then repeat: 1663 / 504

Advancing to step 4:
1663 divided by 504 is 3 with a remainder of 151.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 1512 from 1663, we get 151.
Bring next digit (4) of the dividend behind the 151 and repeat the process: 1514 / 504

Advancing to step 5:
The number 504 fits into 1514 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 33.0
If we subtract 1512 from 1514, we get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 504

Let's proceed to step 6:
The number 504 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 330.0
Subtract 0 from 23 to get 23.
Bring next digit (7) of the dividend behind the 23 and repeat the process: 237 / 504

Going ahead to step 7:
If we divide 237 by 504, we get 0 and a remainder of 237.
Put 0 as the next digit of the answer. 
Result so far: 3300.0
Subtract 0 from 237 to get 237.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2370, and continue the process.

Let's proceed to step 8:
504 goes into 2370 4 times with a remainder of 354.
Put 4 as the next digit of the answer. 
Result so far: 3300.4
The remainder is 354 after subtracting 2016 from 2370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Step 9:
504 can be fit into 3540 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 3300.47
The remainder is 12 after subtracting 3528 from 3540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 10:
If we divide 120 by 504, we get 0 and a remainder of 120.
Put 0 as the next digit of the answer. 
Result so far: 3300.47
Subtracting 0 from 120 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
The number 504 fits into 1200 2 times, leaving a remainder of 192.
Write down 2 as next digit of the result. 
Result so far: 3300.4702
If we take 1008 away from 1200, we end up with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Let's proceed to step 12:
If we divide 1920 by 504, we get 3 and a remainder of 408.
Use 3 as the next digit of our solution. 
Result so far: 3300.47023
If we subtract 1512 from 1920, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

On to step 13:
The number 504 fits into 4080 8 times, leaving a remainder of 48.
Record the quotient 8 as the next digit in the result. 
Result so far: 3300.470238
Subtract 4032 from 4080 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 14:
If we divide 480 by 504, we get 0 and a remainder of 480.
Use 0 as the next digit of our solution. 
Result so far: 3300.470238
The remainder is 480 after subtracting 0 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Let's proceed to step 15:
The number 504 fits into 4800 9 times, leaving a remainder of 264.
Write down 9 as next digit of the result. 
Result so far: 3300.47023809
If we subtract 4536 from 4800, we get 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

After the division, we end up with 3300.47023809 and a remainder of 2.64e-07.
