491338 ÷ 72 
We want to figure out the number of times 491338 can be divided by 72.

Step 1:
72 goes into 4 0 times with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 72

Advancing to step 2:
When dividing 49 by 72, we get 0 with a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 49 after subtracting 0 from 49.
Append the next digit (1) from the dividend to 49 and continue with: 491 / 72

Advancing to step 3:
If we divide 491 by 72, we get 6 and a remainder of 59.
The next digit of our result is 6. 
Result so far: 6.0
Subtract 432 from 491 to get 59.
Bring next digit (3) of the dividend behind the 59 and repeat the process: 593 / 72

Step 4:
72 can be fit into 593 8 times, resulting in a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 68.0
If we subtract 576 from 593, we get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 72

On to step 5:
72 can be fit into 173 2 times, resulting in a remainder of 29.
Record the quotient 2 as the next digit in the result. 
Result so far: 682.0
If we take 144 away from 173, we end up with 29.
Append the next digit (8) from the dividend to 29 and continue with: 298 / 72

Going ahead to step 6:
The number 72 fits into 298 4 times, leaving a remainder of 10.
The next digit of our result is 4. 
Result so far: 6824.0
Deduct 288 from 298 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
72 goes into 100 1 times with a remainder of 28.
Record the quotient 1 as the next digit in the result. 
Result so far: 6824.1
If we subtract 72 from 100, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 8:
280 divided by 72 is 3 with a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 6824.13
The remainder is 64 after subtracting 216 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Moving on to step 9:
If we divide 640 by 72, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 6824.138
Deduct 576 from 640 and we're left with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 10:
72 can be fit into 640 8 times, resulting in a remainder of 64.
The next digit of our result is 8. 
Result so far: 6824.1388
The remainder is 64 after subtracting 576 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

The final result is 6824.1388 with a remainder of 0.00064.
