64161563 divided by 491 
We want to divide 64161563 by 491.

Moving on to step 1:
491 goes into 6 0 times with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (4) from the dividend after 6, then repeat: 64 / 491

Going ahead to step 2:
491 goes into 64 0 times with a remainder of 64.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Take the next digit (1) from the dividend and append it to 64, then repeat: 641 / 491

Advancing to step 3:
If we divide 641 by 491, we get 1 and a remainder of 150.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 491 from 641 and we're left with 150.
Grab the next digit (6) from the dividend, add it to 150, then carry on: 1506 / 491

Moving on to step 4:
491 goes into 1506 3 times with a remainder of 33.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtracting 1473 from 1506 leaves us with 33.
Bring next digit (1) of the dividend behind the 33 and repeat the process: 331 / 491

Moving on to step 5:
331 divided by 491 is 0 with a remainder of 331.
Use 0 as the next digit of our solution. 
Result so far: 130.0
The remainder is 331 after subtracting 0 from 331.
Take the next digit (5) from the dividend and append it to 331, then repeat: 3315 / 491

Going ahead to step 6:
491 can be fit into 3315 6 times, resulting in a remainder of 369.
Write down 6 as next digit of the result. 
Result so far: 1306.0
Subtract 2946 from 3315 to get 369.
Grab the next digit (6) from the dividend, add it to 369, then carry on: 3696 / 491

Going ahead to step 7:
3696 divided by 491 is 7 with a remainder of 259.
Put 7 as the next digit of the answer. 
Result so far: 13067.0
If we subtract 3437 from 3696, we get 259.
Include the next digit (3) from the dividend after 259, then repeat: 2593 / 491

Step 8:
When dividing 2593 by 491, we get 5 with a remainder of 138.
Record the quotient 5 as the next digit in the result. 
Result so far: 130675.0
Subtract 2455 from 2593 to get 138.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1380, and continue the process.

Let's proceed to step 9:
1380 divided by 491 is 2 with a remainder of 398.
Put 2 as the next digit of the answer. 
Result so far: 130675.2
Subtracting 982 from 1380 leaves us with 398.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3980, and continue the process.

Advancing to step 10:
The number 491 fits into 3980 8 times, leaving a remainder of 52.
The next digit of our result is 8. 
Result so far: 130675.28
Subtracting 3928 from 3980 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 11:
520 divided by 491 is 1 with a remainder of 29.
Use 1 as the next digit of our solution. 
Result so far: 130675.281
Subtract 491 from 520 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 12:
When dividing 290 by 491, we get 0 with a remainder of 290.
Record the quotient 0 as the next digit in the result. 
Result so far: 130675.281
Subtract 0 from 290 to get 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Step 13:
When dividing 2900 by 491, we get 5 with a remainder of 445.
The next digit of our result is 5. 
Result so far: 130675.28105
Deduct 2455 from 2900 and we're left with 445.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4450, and continue the process.

Let's proceed to step 14:
491 can be fit into 4450 9 times, resulting in a remainder of 31.
Write down 9 as next digit of the result. 
Result so far: 130675.281059
The remainder is 31 after subtracting 4419 from 4450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 15:
491 goes into 310 0 times with a remainder of 310.
Use 0 as the next digit of our solution. 
Result so far: 130675.281059
The remainder is 310 after subtracting 0 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Moving on to step 16:
491 goes into 3100 6 times with a remainder of 154.
Put 6 as the next digit of the answer. 
Result so far: 130675.28105906
If we take 2946 away from 3100, we end up with 154.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1540, and continue the process.

The final outcome is 130675.28105906, with a leftover of 1.54e-07.
