20991682 divided by 504 
Our goal is to divide 20991682 by 504.

Moving on to step 1:
2 divided by 504 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 504

Moving on to step 2:
The number 504 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (9) from the dividend, add it to 20, then carry on: 209 / 504

Moving on to step 3:
The number 504 fits into 209 0 times, leaving a remainder of 209.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 209, we end up with 209.
Grab the next digit (9) from the dividend, add it to 209, then carry on: 2099 / 504

Let's proceed to step 4:
2099 divided by 504 is 4 with a remainder of 83.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 2016 from 2099 and we're left with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 504

On to step 5:
The number 504 fits into 831 1 times, leaving a remainder of 327.
The number 1 becomes the next digit in our result. 
Result so far: 41.0
Deduct 504 from 831 and we're left with 327.
Include the next digit (6) from the dividend after 327, then repeat: 3276 / 504

Going ahead to step 6:
504 goes into 3276 6 times with a remainder of 252.
Put 6 as the next digit of the answer. 
Result so far: 416.0
If we take 3024 away from 3276, we end up with 252.
Bring next digit (8) of the dividend behind the 252 and repeat the process: 2528 / 504

Advancing to step 7:
When dividing 2528 by 504, we get 5 with a remainder of 8.
Put 5 as the next digit of the answer. 
Result so far: 4165.0
If we take 2520 away from 2528, we end up with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 504

Let's proceed to step 8:
504 can be fit into 82 0 times, resulting in a remainder of 82.
Record the quotient 0 as the next digit in the result. 
Result so far: 41650.0
The remainder is 82 after subtracting 0 from 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
When dividing 820 by 504, we get 1 with a remainder of 316.
Write down 1 as next digit of the result. 
Result so far: 41650.1
The remainder is 316 after subtracting 504 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3160, and continue the process.

On to step 10:
The number 504 fits into 3160 6 times, leaving a remainder of 136.
The number 6 becomes the next digit in our result. 
Result so far: 41650.16
Subtracting 3024 from 3160 leaves us with 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

Step 11:
If we divide 1360 by 504, we get 2 and a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 41650.162
The remainder is 352 after subtracting 1008 from 1360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 12:
504 can be fit into 3520 6 times, resulting in a remainder of 496.
The number 6 becomes the next digit in our result. 
Result so far: 41650.1626
Subtracting 3024 from 3520 leaves us with 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Advancing to step 13:
504 goes into 4960 9 times with a remainder of 424.
Write down 9 as next digit of the result. 
Result so far: 41650.16269
Subtract 4536 from 4960 to get 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Step 14:
504 goes into 4240 8 times with a remainder of 208.
Write down 8 as next digit of the result. 
Result so far: 41650.162698
The remainder is 208 after subtracting 4032 from 4240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Going ahead to step 15:
2080 divided by 504 is 4 with a remainder of 64.
Write down 4 as next digit of the result. 
Result so far: 41650.1626984
Subtract 2016 from 2080 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 16:
The number 504 fits into 640 1 times, leaving a remainder of 136.
Write down 1 as next digit of the result. 
Result so far: 41650.16269841
Subtract 504 from 640 to get 136.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1360, and continue the process.

The final outcome is 41650.16269841, with a leftover of 1.36e-07.
