491965 ÷ 28 
We want to figure out the number of times 491965 can be divided by 28.

Advancing to step 1:
When dividing 4 by 28, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 28

Moving on to step 2:
28 goes into 49 1 times with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 28 from 49, we get 21.
Append the next digit (1) from the dividend to 21 and continue with: 211 / 28

Advancing to step 3:
28 goes into 211 7 times with a remainder of 15.
Use 7 as the next digit of our solution. 
Result so far: 17.0
Subtract 196 from 211 to get 15.
Bring next digit (9) of the dividend behind the 15 and repeat the process: 159 / 28

Step 4:
28 goes into 159 5 times with a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 175.0
Subtracting 140 from 159 leaves us with 19.
Bring next digit (6) of the dividend behind the 19 and repeat the process: 196 / 28

Advancing to step 5:
28 goes into 196 7 times with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 1757.0
If we subtract 196 from 196, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 28

Going ahead to step 6:
When dividing 5 by 28, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 17570.0
If we subtract 0 from 5, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 7:
28 goes into 50 1 times with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 17570.1
Subtract 28 from 50 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
220 divided by 28 is 7 with a remainder of 24.
Use 7 as the next digit of our solution. 
Result so far: 17570.17
The remainder is 24 after subtracting 196 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Step 9:
240 divided by 28 is 8 with a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 17570.178
Subtracting 224 from 240 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 17570.1785
Deduct 140 from 160 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
28 goes into 200 7 times with a remainder of 4.
The next digit of our result is 7. 
Result so far: 17570.17857
The remainder is 4 after subtracting 196 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
28 goes into 40 1 times with a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 17570.178571
If we subtract 28 from 40, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 13:
The number 28 fits into 120 4 times, leaving a remainder of 8.
Use 4 as the next digit of our solution. 
Result so far: 17570.1785714
Deduct 112 from 120 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 14:
When dividing 80 by 28, we get 2 with a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 17570.17857142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 17570.17857142, with a leftover of 2.4e-08.
