Let's divide 20665941 by 504
Our goal is to divide 20665941 by 504.

Advancing to step 1:
2 divided by 504 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 504

Step 2:
504 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 20 leaves us with 20.
Append the next digit (6) from the dividend to 20 and continue with: 206 / 504

Advancing to step 3:
The number 504 fits into 206 0 times, leaving a remainder of 206.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 206 and we're left with 206.
Bring next digit (6) of the dividend behind the 206 and repeat the process: 2066 / 504

Let's proceed to step 4:
When dividing 2066 by 504, we get 4 with a remainder of 50.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 2016 from 2066, we get 50.
Append the next digit (5) from the dividend to 50 and continue with: 505 / 504

Moving on to step 5:
The number 504 fits into 505 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 41.0
If we subtract 504 from 505, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 504

Step 6:
504 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 410.0
If we subtract 0 from 19, we get 19.
Append the next digit (4) from the dividend to 19 and continue with: 194 / 504

Moving on to step 7:
504 can be fit into 194 0 times, resulting in a remainder of 194.
Use 0 as the next digit of our solution. 
Result so far: 4100.0
The remainder is 194 after subtracting 0 from 194.
Append the next digit (1) from the dividend to 194 and continue with: 1941 / 504

Moving on to step 8:
504 can be fit into 1941 3 times, resulting in a remainder of 429.
Use 3 as the next digit of our solution. 
Result so far: 41003.0
The remainder is 429 after subtracting 1512 from 1941.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4290, and continue the process.

On to step 9:
When dividing 4290 by 504, we get 8 with a remainder of 258.
Record the quotient 8 as the next digit in the result. 
Result so far: 41003.8
Subtracting 4032 from 4290 leaves us with 258.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2580, and continue the process.

Advancing to step 10:
504 can be fit into 2580 5 times, resulting in a remainder of 60.
Put 5 as the next digit of the answer. 
Result so far: 41003.85
If we subtract 2520 from 2580, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 11:
When dividing 600 by 504, we get 1 with a remainder of 96.
Record the quotient 1 as the next digit in the result. 
Result so far: 41003.851
The remainder is 96 after subtracting 504 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Let's proceed to step 12:
If we divide 960 by 504, we get 1 and a remainder of 456.
Put 1 as the next digit of the answer. 
Result so far: 41003.8511
Subtract 504 from 960 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

After the division, we end up with 41003.8511 and a remainder of 0.00456.
