We're dividing 16691961 by 491 
Let's see how many times 491 fits into 16691961.

Step 1:
The number 491 fits into 1 0 times, leaving a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 491

Step 2:
491 goes into 16 0 times with a remainder of 16.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 491

Step 3:
If we divide 166 by 491, we get 0 and a remainder of 166.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 166, we end up with 166.
Take the next digit (9) from the dividend and append it to 166, then repeat: 1669 / 491

Step 4:
1669 divided by 491 is 3 with a remainder of 196.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 196 after subtracting 1473 from 1669.
Fetch the next digit (1) from the dividend, attach it to 196 and continue: 1961 / 491

Moving on to step 5:
491 can be fit into 1961 3 times, resulting in a remainder of 488.
The next digit of our result is 3. 
Result so far: 33.0
The remainder is 488 after subtracting 1473 from 1961.
Bring next digit (9) of the dividend behind the 488 and repeat the process: 4889 / 491

Moving on to step 6:
If we divide 4889 by 491, we get 9 and a remainder of 470.
Use 9 as the next digit of our solution. 
Result so far: 339.0
Subtracting 4419 from 4889 leaves us with 470.
Fetch the next digit (6) from the dividend, attach it to 470 and continue: 4706 / 491

On to step 7:
If we divide 4706 by 491, we get 9 and a remainder of 287.
The number 9 becomes the next digit in our result. 
Result so far: 3399.0
If we take 4419 away from 4706, we end up with 287.
Grab the next digit (1) from the dividend, add it to 287, then carry on: 2871 / 491

Step 8:
2871 divided by 491 is 5 with a remainder of 416.
Write down 5 as next digit of the result. 
Result so far: 33995.0
Deduct 2455 from 2871 and we're left with 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

Moving on to step 9:
491 can be fit into 4160 8 times, resulting in a remainder of 232.
The next digit of our result is 8. 
Result so far: 33995.8
Subtract 3928 from 4160 to get 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Advancing to step 10:
491 can be fit into 2320 4 times, resulting in a remainder of 356.
Record the quotient 4 as the next digit in the result. 
Result so far: 33995.84
Deduct 1964 from 2320 and we're left with 356.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

Step 11:
3560 divided by 491 is 7 with a remainder of 123.
Use 7 as the next digit of our solution. 
Result so far: 33995.847
The remainder is 123 after subtracting 3437 from 3560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1230, and continue the process.

Advancing to step 12:
1230 divided by 491 is 2 with a remainder of 248.
The number 2 becomes the next digit in our result. 
Result so far: 33995.8472
The remainder is 248 after subtracting 982 from 1230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 13:
491 can be fit into 2480 5 times, resulting in a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 33995.84725
Deduct 2455 from 2480 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 14:
If we divide 250 by 491, we get 0 and a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 33995.84725
Subtract 0 from 250 to get 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Moving on to step 15:
The number 491 fits into 2500 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 33995.8472505
Subtract 2455 from 2500 to get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 16:
491 goes into 450 0 times with a remainder of 450.
Record the quotient 0 as the next digit in the result. 
Result so far: 33995.8472505
If we take 0 away from 450, we end up with 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4500, and continue the process.

After the division, we end up with 33995.8472505 and a remainder of 4.5e-07.
