89012839 divided by 491 
We want to divide 89012839 by 491.

Step 1:
491 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 491

On to step 2:
When dividing 89 by 491, we get 0 with a remainder of 89.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Include the next digit (0) from the dividend after 89, then repeat: 890 / 491

On to step 3:
When dividing 890 by 491, we get 1 with a remainder of 399.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 399 after subtracting 491 from 890.
Take the next digit (1) from the dividend and append it to 399, then repeat: 3991 / 491

Step 4:
If we divide 3991 by 491, we get 8 and a remainder of 63.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Deduct 3928 from 3991 and we're left with 63.
Bring next digit (2) of the dividend behind the 63 and repeat the process: 632 / 491

Going ahead to step 5:
If we divide 632 by 491, we get 1 and a remainder of 141.
Put 1 as the next digit of the answer. 
Result so far: 181.0
If we subtract 491 from 632, we get 141.
Include the next digit (8) from the dividend after 141, then repeat: 1418 / 491

Let's proceed to step 6:
1418 divided by 491 is 2 with a remainder of 436.
Use 2 as the next digit of our solution. 
Result so far: 1812.0
Subtract 982 from 1418 to get 436.
Bring next digit (3) of the dividend behind the 436 and repeat the process: 4363 / 491

On to step 7:
The number 491 fits into 4363 8 times, leaving a remainder of 435.
Record the quotient 8 as the next digit in the result. 
Result so far: 18128.0
Subtract 3928 from 4363 to get 435.
Append the next digit (9) from the dividend to 435 and continue with: 4359 / 491

Moving on to step 8:
491 goes into 4359 8 times with a remainder of 431.
Record the quotient 8 as the next digit in the result. 
Result so far: 181288.0
Subtracting 3928 from 4359 leaves us with 431.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4310, and continue the process.

On to step 9:
491 goes into 4310 8 times with a remainder of 382.
Put 8 as the next digit of the answer. 
Result so far: 181288.8
Subtracting 3928 from 4310 leaves us with 382.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3820, and continue the process.

Let's proceed to step 10:
491 can be fit into 3820 7 times, resulting in a remainder of 383.
Put 7 as the next digit of the answer. 
Result so far: 181288.87
Deduct 3437 from 3820 and we're left with 383.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3830, and continue the process.

Going ahead to step 11:
491 goes into 3830 7 times with a remainder of 393.
The next digit of our result is 7. 
Result so far: 181288.877
Deduct 3437 from 3830 and we're left with 393.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3930, and continue the process.

The final outcome is 181288.877, with a leftover of 0.0393.
