80458060 divided by 491 
We want to divide 80458060 by 491.

On to step 1:
491 can be fit into 8 0 times, resulting in a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 491

Advancing to step 2:
When dividing 80 by 491, we get 0 with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Bring next digit (4) of the dividend behind the 80 and repeat the process: 804 / 491

Let's proceed to step 3:
If we divide 804 by 491, we get 1 and a remainder of 313.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 491 from 804 to get 313.
Include the next digit (5) from the dividend after 313, then repeat: 3135 / 491

Advancing to step 4:
491 can be fit into 3135 6 times, resulting in a remainder of 189.
Put 6 as the next digit of the answer. 
Result so far: 16.0
Deduct 2946 from 3135 and we're left with 189.
Take the next digit (8) from the dividend and append it to 189, then repeat: 1898 / 491

Step 5:
The number 491 fits into 1898 3 times, leaving a remainder of 425.
Put 3 as the next digit of the answer. 
Result so far: 163.0
If we take 1473 away from 1898, we end up with 425.
Grab the next digit (0) from the dividend, add it to 425, then carry on: 4250 / 491

Moving on to step 6:
If we divide 4250 by 491, we get 8 and a remainder of 322.
Use 8 as the next digit of our solution. 
Result so far: 1638.0
Subtract 3928 from 4250 to get 322.
Bring next digit (6) of the dividend behind the 322 and repeat the process: 3226 / 491

Going ahead to step 7:
491 can be fit into 3226 6 times, resulting in a remainder of 280.
The next digit of our result is 6. 
Result so far: 16386.0
The remainder is 280 after subtracting 2946 from 3226.
Append the next digit (0) from the dividend to 280 and continue with: 2800 / 491

Advancing to step 8:
2800 divided by 491 is 5 with a remainder of 345.
The next digit of our result is 5. 
Result so far: 163865.0
Subtract 2455 from 2800 to get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

Moving on to step 9:
The number 491 fits into 3450 7 times, leaving a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 163865.7
Subtracting 3437 from 3450 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 10:
491 goes into 130 0 times with a remainder of 130.
Write down 0 as next digit of the result. 
Result so far: 163865.7
If we subtract 0 from 130, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
491 goes into 1300 2 times with a remainder of 318.
The next digit of our result is 2. 
Result so far: 163865.702
If we take 982 away from 1300, we end up with 318.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3180, and continue the process.

On to step 12:
When dividing 3180 by 491, we get 6 with a remainder of 234.
Put 6 as the next digit of the answer. 
Result so far: 163865.7026
If we take 2946 away from 3180, we end up with 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2340, and continue the process.

On to step 13:
2340 divided by 491 is 4 with a remainder of 376.
The next digit of our result is 4. 
Result so far: 163865.70264
Subtracting 1964 from 2340 leaves us with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Advancing to step 14:
The number 491 fits into 3760 7 times, leaving a remainder of 323.
Record the quotient 7 as the next digit in the result. 
Result so far: 163865.702647
The remainder is 323 after subtracting 3437 from 3760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3230, and continue the process.

Let's proceed to step 15:
491 goes into 3230 6 times with a remainder of 284.
Put 6 as the next digit of the answer. 
Result so far: 163865.7026476
Subtract 2946 from 3230 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Going ahead to step 16:
2840 divided by 491 is 5 with a remainder of 385.
Write down 5 as next digit of the result. 
Result so far: 163865.70264765
The remainder is 385 after subtracting 2455 from 2840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

Our division results in 163865.70264765 with a remaining 3.85e-07.
