We're dividing 21321016 by 493 
We're looking to find how many times 493 goes into 21321016.

Step 1:
The number 493 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 493

Going ahead to step 2:
The number 493 fits into 21 0 times, leaving a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 21, we get 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 493

Step 3:
The number 493 fits into 213 0 times, leaving a remainder of 213.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 213 leaves us with 213.
Fetch the next digit (2) from the dividend, attach it to 213 and continue: 2132 / 493

Moving on to step 4:
493 can be fit into 2132 4 times, resulting in a remainder of 160.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 1972 from 2132 to get 160.
Append the next digit (1) from the dividend to 160 and continue with: 1601 / 493

Moving on to step 5:
When dividing 1601 by 493, we get 3 with a remainder of 122.
The number 3 becomes the next digit in our result. 
Result so far: 43.0
Subtracting 1479 from 1601 leaves us with 122.
Fetch the next digit (0) from the dividend, attach it to 122 and continue: 1220 / 493

Let's proceed to step 6:
When dividing 1220 by 493, we get 2 with a remainder of 234.
The next digit of our result is 2. 
Result so far: 432.0
Subtracting 986 from 1220 leaves us with 234.
Grab the next digit (1) from the dividend, add it to 234, then carry on: 2341 / 493

Advancing to step 7:
2341 divided by 493 is 4 with a remainder of 369.
The number 4 becomes the next digit in our result. 
Result so far: 4324.0
Deduct 1972 from 2341 and we're left with 369.
Grab the next digit (6) from the dividend, add it to 369, then carry on: 3696 / 493

On to step 8:
493 goes into 3696 7 times with a remainder of 245.
Put 7 as the next digit of the answer. 
Result so far: 43247.0
Subtracting 3451 from 3696 leaves us with 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

Let's proceed to step 9:
493 goes into 2450 4 times with a remainder of 478.
Record the quotient 4 as the next digit in the result. 
Result so far: 43247.4
The remainder is 478 after subtracting 1972 from 2450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4780, and continue the process.

On to step 10:
493 can be fit into 4780 9 times, resulting in a remainder of 343.
Write down 9 as next digit of the result. 
Result so far: 43247.49
If we take 4437 away from 4780, we end up with 343.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3430, and continue the process.

Going ahead to step 11:
When dividing 3430 by 493, we get 6 with a remainder of 472.
The next digit of our result is 6. 
Result so far: 43247.496
Subtract 2958 from 3430 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Step 12:
If we divide 4720 by 493, we get 9 and a remainder of 283.
The next digit of our result is 9. 
Result so far: 43247.4969
Subtract 4437 from 4720 to get 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 13:
If we divide 2830 by 493, we get 5 and a remainder of 365.
Record the quotient 5 as the next digit in the result. 
Result so far: 43247.49695
The remainder is 365 after subtracting 2465 from 2830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Moving on to step 14:
493 can be fit into 3650 7 times, resulting in a remainder of 199.
Put 7 as the next digit of the answer. 
Result so far: 43247.496957
If we take 3451 away from 3650, we end up with 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

On to step 15:
493 goes into 1990 4 times with a remainder of 18.
Write down 4 as next digit of the result. 
Result so far: 43247.4969574
Subtract 1972 from 1990 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 16:
180 divided by 493 is 0 with a remainder of 180.
The next digit of our result is 0. 
Result so far: 43247.4969574
Subtract 0 from 180 to get 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 43247.4969574 and a remainder of 1.8e-07.
