20916392 divided by 491 
Let's see how many times 491 fits into 20916392.

On to step 1:
491 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
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 / 491

Step 2:
The number 491 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 20, we get 20.
Bring next digit (9) of the dividend behind the 20 and repeat the process: 209 / 491

Step 3:
The number 491 fits into 209 0 times, leaving a remainder of 209.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 209 leaves us with 209.
Grab the next digit (1) from the dividend, add it to 209, then carry on: 2091 / 491

Advancing to step 4:
If we divide 2091 by 491, we get 4 and a remainder of 127.
Write down 4 as next digit of the result. 
Result so far: 4.0
The remainder is 127 after subtracting 1964 from 2091.
Take the next digit (6) from the dividend and append it to 127, then repeat: 1276 / 491

Step 5:
The number 491 fits into 1276 2 times, leaving a remainder of 294.
The next digit of our result is 2. 
Result so far: 42.0
If we subtract 982 from 1276, we get 294.
Grab the next digit (3) from the dividend, add it to 294, then carry on: 2943 / 491

Moving on to step 6:
491 goes into 2943 5 times with a remainder of 488.
The number 5 becomes the next digit in our result. 
Result so far: 425.0
Deduct 2455 from 2943 and we're left with 488.
Grab the next digit (9) from the dividend, add it to 488, then carry on: 4889 / 491

Going ahead to step 7:
If we divide 4889 by 491, we get 9 and a remainder of 470.
Record the quotient 9 as the next digit in the result. 
Result so far: 4259.0
If we take 4419 away from 4889, we end up with 470.
Take the next digit (2) from the dividend and append it to 470, then repeat: 4702 / 491

On to step 8:
When dividing 4702 by 491, we get 9 with a remainder of 283.
Put 9 as the next digit of the answer. 
Result so far: 42599.0
Deduct 4419 from 4702 and we're left with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Going ahead to step 9:
When dividing 2830 by 491, we get 5 with a remainder of 375.
Write down 5 as next digit of the result. 
Result so far: 42599.5
If we subtract 2455 from 2830, we get 375.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3750, and continue the process.

Moving on to step 10:
If we divide 3750 by 491, we get 7 and a remainder of 313.
The next digit of our result is 7. 
Result so far: 42599.57
The remainder is 313 after subtracting 3437 from 3750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Going ahead to step 11:
The number 491 fits into 3130 6 times, leaving a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 42599.576
If we subtract 2946 from 3130, we get 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

Let's proceed to step 12:
The number 491 fits into 1840 3 times, leaving a remainder of 367.
The next digit of our result is 3. 
Result so far: 42599.5763
Deduct 1473 from 1840 and we're left with 367.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3670, and continue the process.

On to step 13:
The number 491 fits into 3670 7 times, leaving a remainder of 233.
Use 7 as the next digit of our solution. 
Result so far: 42599.57637
Subtract 3437 from 3670 to get 233.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2330, and continue the process.

On to step 14:
491 goes into 2330 4 times with a remainder of 366.
The number 4 becomes the next digit in our result. 
Result so far: 42599.576374
Subtract 1964 from 2330 to get 366.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3660, and continue the process.

Step 15:
491 goes into 3660 7 times with a remainder of 223.
The number 7 becomes the next digit in our result. 
Result so far: 42599.5763747
The remainder is 223 after subtracting 3437 from 3660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

On to step 16:
491 goes into 2230 4 times with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 42599.57637474
Subtracting 1964 from 2230 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Our division results in 42599.57637474 with a remaining 2.66e-07.
