We look at the division of 21764649 by 503 
We want to figure out the number of times 21764649 can be divided by 503.

Let's proceed to step 1:
2 divided by 503 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 503

Step 2:
The number 503 fits into 21 0 times, leaving a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 21 to get 21.
Take the next digit (7) from the dividend and append it to 21, then repeat: 217 / 503

Step 3:
503 can be fit into 217 0 times, resulting in a remainder of 217.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 217, we get 217.
Bring next digit (6) of the dividend behind the 217 and repeat the process: 2176 / 503

Moving on to step 4:
When dividing 2176 by 503, we get 4 with a remainder of 164.
The next digit of our result is 4. 
Result so far: 4.0
Deduct 2012 from 2176 and we're left with 164.
Include the next digit (4) from the dividend after 164, then repeat: 1644 / 503

Moving on to step 5:
If we divide 1644 by 503, we get 3 and a remainder of 135.
Record the quotient 3 as the next digit in the result. 
Result so far: 43.0
If we subtract 1509 from 1644, we get 135.
Append the next digit (6) from the dividend to 135 and continue with: 1356 / 503

On to step 6:
503 goes into 1356 2 times with a remainder of 350.
Put 2 as the next digit of the answer. 
Result so far: 432.0
Deduct 1006 from 1356 and we're left with 350.
Fetch the next digit (4) from the dividend, attach it to 350 and continue: 3504 / 503

Step 7:
If we divide 3504 by 503, we get 6 and a remainder of 486.
Put 6 as the next digit of the answer. 
Result so far: 4326.0
If we subtract 3018 from 3504, we get 486.
Fetch the next digit (9) from the dividend, attach it to 486 and continue: 4869 / 503

Step 8:
When dividing 4869 by 503, we get 9 with a remainder of 342.
Record the quotient 9 as the next digit in the result. 
Result so far: 43269.0
If we take 4527 away from 4869, we end up with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Advancing to step 9:
If we divide 3420 by 503, we get 6 and a remainder of 402.
Put 6 as the next digit of the answer. 
Result so far: 43269.6
Subtract 3018 from 3420 to get 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Moving on to step 10:
4020 divided by 503 is 7 with a remainder of 499.
Record the quotient 7 as the next digit in the result. 
Result so far: 43269.67
Subtract 3521 from 4020 to get 499.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4990, and continue the process.

Let's proceed to step 11:
503 can be fit into 4990 9 times, resulting in a remainder of 463.
The number 9 becomes the next digit in our result. 
Result so far: 43269.679
The remainder is 463 after subtracting 4527 from 4990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4630, and continue the process.

Advancing to step 12:
The number 503 fits into 4630 9 times, leaving a remainder of 103.
The number 9 becomes the next digit in our result. 
Result so far: 43269.6799
Subtracting 4527 from 4630 leaves us with 103.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1030, and continue the process.

Our division results in 43269.6799 with a remaining 0.00103.
