80346326 divided by 491 
We want to divide 80346326 by 491.

Going ahead to step 1:
When dividing 8 by 491, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 491

On to step 2:
The number 491 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 491

Step 3:
491 goes into 803 1 times with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 491 from 803 to get 312.
Grab the next digit (4) from the dividend, add it to 312, then carry on: 3124 / 491

Moving on to step 4:
When dividing 3124 by 491, we get 6 with a remainder of 178.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 2946 from 3124, we get 178.
Bring next digit (6) of the dividend behind the 178 and repeat the process: 1786 / 491

Moving on to step 5:
If we divide 1786 by 491, we get 3 and a remainder of 313.
Put 3 as the next digit of the answer. 
Result so far: 163.0
Deduct 1473 from 1786 and we're left with 313.
Include the next digit (3) from the dividend after 313, then repeat: 3133 / 491

On to step 6:
3133 divided by 491 is 6 with a remainder of 187.
Record the quotient 6 as the next digit in the result. 
Result so far: 1636.0
Deduct 2946 from 3133 and we're left with 187.
Grab the next digit (2) from the dividend, add it to 187, then carry on: 1872 / 491

Let's proceed to step 7:
491 goes into 1872 3 times with a remainder of 399.
Put 3 as the next digit of the answer. 
Result so far: 16363.0
The remainder is 399 after subtracting 1473 from 1872.
Append the next digit (6) from the dividend to 399 and continue with: 3996 / 491

Step 8:
When dividing 3996 by 491, we get 8 with a remainder of 68.
The number 8 becomes the next digit in our result. 
Result so far: 163638.0
Subtracting 3928 from 3996 leaves us with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Going ahead to step 9:
491 can be fit into 680 1 times, resulting in a remainder of 189.
Record the quotient 1 as the next digit in the result. 
Result so far: 163638.1
If we subtract 491 from 680, we get 189.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1890, and continue the process.

On to step 10:
491 can be fit into 1890 3 times, resulting in a remainder of 417.
The next digit of our result is 3. 
Result so far: 163638.13
Subtracting 1473 from 1890 leaves us with 417.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4170, and continue the process.

Advancing to step 11:
491 can be fit into 4170 8 times, resulting in a remainder of 242.
The number 8 becomes the next digit in our result. 
Result so far: 163638.138
Subtract 3928 from 4170 to get 242.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2420, and continue the process.

Step 12:
491 goes into 2420 4 times with a remainder of 456.
Put 4 as the next digit of the answer. 
Result so far: 163638.1384
Subtract 1964 from 2420 to get 456.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4560, and continue the process.

On to step 13:
491 can be fit into 4560 9 times, resulting in a remainder of 141.
Use 9 as the next digit of our solution. 
Result so far: 163638.13849
If we subtract 4419 from 4560, we get 141.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1410, and continue the process.

Moving on to step 14:
491 can be fit into 1410 2 times, resulting in a remainder of 428.
Record the quotient 2 as the next digit in the result. 
Result so far: 163638.138492
If we subtract 982 from 1410, we get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 15:
491 goes into 4280 8 times with a remainder of 352.
Write down 8 as next digit of the result. 
Result so far: 163638.1384928
Deduct 3928 from 4280 and we're left with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 16:
3520 divided by 491 is 7 with a remainder of 83.
Record the quotient 7 as the next digit in the result. 
Result so far: 163638.13849287
Subtracting 3437 from 3520 leaves us with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

Our division results in 163638.13849287 with a remaining 8.3e-08.
