We're dividing 21528014 by 503 
Let's see how many times 503 fits into 21528014.

Let's proceed to step 1:
The number 503 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 503

Moving on to step 2:
21 divided by 503 is 0 with a remainder of 21.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Include the next digit (5) from the dividend after 21, then repeat: 215 / 503

Moving on to step 3:
When dividing 215 by 503, we get 0 with a remainder of 215.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 215, we end up with 215.
Bring next digit (2) of the dividend behind the 215 and repeat the process: 2152 / 503

On to step 4:
If we divide 2152 by 503, we get 4 and a remainder of 140.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 2012 from 2152 to get 140.
Bring next digit (8) of the dividend behind the 140 and repeat the process: 1408 / 503

Let's proceed to step 5:
The number 503 fits into 1408 2 times, leaving a remainder of 402.
Record the quotient 2 as the next digit in the result. 
Result so far: 42.0
Subtracting 1006 from 1408 leaves us with 402.
Grab the next digit (0) from the dividend, add it to 402, then carry on: 4020 / 503

Let's proceed to step 6:
4020 divided by 503 is 7 with a remainder of 499.
Put 7 as the next digit of the answer. 
Result so far: 427.0
The remainder is 499 after subtracting 3521 from 4020.
Append the next digit (1) from the dividend to 499 and continue with: 4991 / 503

Moving on to step 7:
4991 divided by 503 is 9 with a remainder of 464.
Write down 9 as next digit of the result. 
Result so far: 4279.0
Subtracting 4527 from 4991 leaves us with 464.
Include the next digit (4) from the dividend after 464, then repeat: 4644 / 503

On to step 8:
503 can be fit into 4644 9 times, resulting in a remainder of 117.
Record the quotient 9 as the next digit in the result. 
Result so far: 42799.0
The remainder is 117 after subtracting 4527 from 4644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1170, and continue the process.

Advancing to step 9:
503 goes into 1170 2 times with a remainder of 164.
Use 2 as the next digit of our solution. 
Result so far: 42799.2
If we take 1006 away from 1170, we end up with 164.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1640, and continue the process.

Moving on to step 10:
If we divide 1640 by 503, we get 3 and a remainder of 131.
Put 3 as the next digit of the answer. 
Result so far: 42799.23
If we subtract 1509 from 1640, we get 131.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 11:
The number 503 fits into 1310 2 times, leaving a remainder of 304.
Put 2 as the next digit of the answer. 
Result so far: 42799.232
If we subtract 1006 from 1310, we get 304.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

Going ahead to step 12:
If we divide 3040 by 503, we get 6 and a remainder of 22.
Use 6 as the next digit of our solution. 
Result so far: 42799.2326
Subtracting 3018 from 3040 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Step 13:
503 can be fit into 220 0 times, resulting in a remainder of 220.
Write down 0 as next digit of the result. 
Result so far: 42799.2326
Deduct 0 from 220 and we're left with 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Advancing to step 14:
When dividing 2200 by 503, we get 4 with a remainder of 188.
Put 4 as the next digit of the answer. 
Result so far: 42799.232604
The remainder is 188 after subtracting 2012 from 2200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1880, and continue the process.

Advancing to step 15:
503 goes into 1880 3 times with a remainder of 371.
Write down 3 as next digit of the result. 
Result so far: 42799.2326043
The remainder is 371 after subtracting 1509 from 1880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3710, and continue the process.

Let's proceed to step 16:
If we divide 3710 by 503, we get 7 and a remainder of 189.
Record the quotient 7 as the next digit in the result. 
Result so far: 42799.23260437
Subtracting 3521 from 3710 leaves us with 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

The final result is 42799.23260437 with a remainder of 1.89e-07.
