64381578 ÷ 494 
Let's see how many times 494 fits into 64381578.

Step 1:
When dividing 6 by 494, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 494

Step 2:
When dividing 64 by 494, we get 0 with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 64 after subtracting 0 from 64.
Bring next digit (3) of the dividend behind the 64 and repeat the process: 643 / 494

On to step 3:
When dividing 643 by 494, we get 1 with a remainder of 149.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 494 away from 643, we end up with 149.
Fetch the next digit (8) from the dividend, attach it to 149 and continue: 1498 / 494

Advancing to step 4:
494 goes into 1498 3 times with a remainder of 16.
The next digit of our result is 3. 
Result so far: 13.0
Deduct 1482 from 1498 and we're left with 16.
Bring next digit (1) of the dividend behind the 16 and repeat the process: 161 / 494

On to step 5:
If we divide 161 by 494, we get 0 and a remainder of 161.
Put 0 as the next digit of the answer. 
Result so far: 130.0
Subtract 0 from 161 to get 161.
Append the next digit (5) from the dividend to 161 and continue with: 1615 / 494

On to step 6:
494 goes into 1615 3 times with a remainder of 133.
The number 3 becomes the next digit in our result. 
Result so far: 1303.0
Subtracting 1482 from 1615 leaves us with 133.
Append the next digit (7) from the dividend to 133 and continue with: 1337 / 494

Step 7:
1337 divided by 494 is 2 with a remainder of 349.
The next digit of our result is 2. 
Result so far: 13032.0
Subtract 988 from 1337 to get 349.
Bring next digit (8) of the dividend behind the 349 and repeat the process: 3498 / 494

Step 8:
If we divide 3498 by 494, we get 7 and a remainder of 40.
The number 7 becomes the next digit in our result. 
Result so far: 130327.0
Subtract 3458 from 3498 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 9:
494 can be fit into 400 0 times, resulting in a remainder of 400.
The next digit of our result is 0. 
Result so far: 130327.0
The remainder is 400 after subtracting 0 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Step 10:
494 goes into 4000 8 times with a remainder of 48.
Put 8 as the next digit of the answer. 
Result so far: 130327.08
Subtracting 3952 from 4000 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 11:
The number 494 fits into 480 0 times, leaving a remainder of 480.
Write down 0 as next digit of the result. 
Result so far: 130327.08
Deduct 0 from 480 and we're left with 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4800, and continue the process.

Step 12:
When dividing 4800 by 494, we get 9 with a remainder of 354.
Record the quotient 9 as the next digit in the result. 
Result so far: 130327.0809
If we subtract 4446 from 4800, we get 354.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3540, and continue the process.

Let's proceed to step 13:
3540 divided by 494 is 7 with a remainder of 82.
Use 7 as the next digit of our solution. 
Result so far: 130327.08097
Subtracting 3458 from 3540 leaves us with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

On to step 14:
When dividing 820 by 494, we get 1 with a remainder of 326.
Put 1 as the next digit of the answer. 
Result so far: 130327.080971
Subtracting 494 from 820 leaves us with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

Step 15:
494 can be fit into 3260 6 times, resulting in a remainder of 296.
The number 6 becomes the next digit in our result. 
Result so far: 130327.0809716
Deduct 2964 from 3260 and we're left with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Let's proceed to step 16:
The number 494 fits into 2960 5 times, leaving a remainder of 490.
Write down 5 as next digit of the result. 
Result so far: 130327.08097165
Subtract 2470 from 2960 to get 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4900, and continue the process.

The final outcome is 130327.08097165, with a leftover of 4.9e-07.
