We divide 78511176 by 491
We want to figure out the number of times 78511176 can be divided by 491.

On to step 1:
The number 491 fits into 7 0 times, leaving a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 491

Advancing to step 2:
When dividing 78 by 491, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 78 to get 78.
Append the next digit (5) from the dividend to 78 and continue with: 785 / 491

Going ahead to step 3:
491 goes into 785 1 times with a remainder of 294.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 491 from 785 and we're left with 294.
Bring next digit (1) of the dividend behind the 294 and repeat the process: 2941 / 491

Step 4:
491 can be fit into 2941 5 times, resulting in a remainder of 486.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
Subtracting 2455 from 2941 leaves us with 486.
Include the next digit (1) from the dividend after 486, then repeat: 4861 / 491

Let's proceed to step 5:
4861 divided by 491 is 9 with a remainder of 442.
Use 9 as the next digit of our solution. 
Result so far: 159.0
Subtracting 4419 from 4861 leaves us with 442.
Bring next digit (1) of the dividend behind the 442 and repeat the process: 4421 / 491

Step 6:
When dividing 4421 by 491, we get 9 with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1599.0
Subtracting 4419 from 4421 leaves us with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 491

Step 7:
When dividing 27 by 491, we get 0 with a remainder of 27.
The number 0 becomes the next digit in our result. 
Result so far: 15990.0
Deduct 0 from 27 and we're left with 27.
Take the next digit (6) from the dividend and append it to 27, then repeat: 276 / 491

Let's proceed to step 8:
When dividing 276 by 491, we get 0 with a remainder of 276.
Record the quotient 0 as the next digit in the result. 
Result so far: 159900.0
If we take 0 away from 276, we end up with 276.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2760, and continue the process.

On to step 9:
When dividing 2760 by 491, we get 5 with a remainder of 305.
Put 5 as the next digit of the answer. 
Result so far: 159900.5
Deduct 2455 from 2760 and we're left with 305.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3050, and continue the process.

Step 10:
If we divide 3050 by 491, we get 6 and a remainder of 104.
The next digit of our result is 6. 
Result so far: 159900.56
The remainder is 104 after subtracting 2946 from 3050.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Advancing to step 11:
491 goes into 1040 2 times with a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 159900.562
Deduct 982 from 1040 and we're left with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 12:
580 divided by 491 is 1 with a remainder of 89.
The number 1 becomes the next digit in our result. 
Result so far: 159900.5621
Subtract 491 from 580 to get 89.
Since there are no more digits in the dividend, we add a zero to the remainder making it 890, and continue the process.

On to step 13:
The number 491 fits into 890 1 times, leaving a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 159900.56211
If we subtract 491 from 890, we get 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3990, and continue the process.

Our division results in 159900.56211 with a remaining 0.000399.
