81264939 divided by 494 
We want to figure out the number of times 81264939 can be divided by 494.

Advancing to step 1:
If we divide 8 by 494, we get 0 and a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 494

Advancing to step 2:
The number 494 fits into 81 0 times, leaving a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 81 leaves us with 81.
Include the next digit (2) from the dividend after 81, then repeat: 812 / 494

Going ahead to step 3:
The number 494 fits into 812 1 times, leaving a remainder of 318.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 494 from 812 and we're left with 318.
Grab the next digit (6) from the dividend, add it to 318, then carry on: 3186 / 494

On to step 4:
494 can be fit into 3186 6 times, resulting in a remainder of 222.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
If we subtract 2964 from 3186, we get 222.
Include the next digit (4) from the dividend after 222, then repeat: 2224 / 494

Step 5:
The number 494 fits into 2224 4 times, leaving a remainder of 248.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
If we subtract 1976 from 2224, we get 248.
Bring next digit (9) of the dividend behind the 248 and repeat the process: 2489 / 494

Going ahead to step 6:
If we divide 2489 by 494, we get 5 and a remainder of 19.
Put 5 as the next digit of the answer. 
Result so far: 1645.0
If we take 2470 away from 2489, we end up with 19.
Grab the next digit (3) from the dividend, add it to 19, then carry on: 193 / 494

Step 7:
494 can be fit into 193 0 times, resulting in a remainder of 193.
Write down 0 as next digit of the result. 
Result so far: 16450.0
If we take 0 away from 193, we end up with 193.
Take the next digit (9) from the dividend and append it to 193, then repeat: 1939 / 494

On to step 8:
1939 divided by 494 is 3 with a remainder of 457.
Record the quotient 3 as the next digit in the result. 
Result so far: 164503.0
If we subtract 1482 from 1939, we get 457.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4570, and continue the process.

On to step 9:
494 can be fit into 4570 9 times, resulting in a remainder of 124.
Use 9 as the next digit of our solution. 
Result so far: 164503.9
Subtracting 4446 from 4570 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 10:
The number 494 fits into 1240 2 times, leaving a remainder of 252.
The next digit of our result is 2. 
Result so far: 164503.92
The remainder is 252 after subtracting 988 from 1240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2520, and continue the process.

Moving on to step 11:
If we divide 2520 by 494, we get 5 and a remainder of 50.
The number 5 becomes the next digit in our result. 
Result so far: 164503.925
If we subtract 2470 from 2520, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

On to step 12:
When dividing 500 by 494, we get 1 with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 164503.9251
If we subtract 494 from 500, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
When dividing 60 by 494, we get 0 with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 164503.9251
Subtract 0 from 60 to get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

On to step 14:
494 goes into 600 1 times with a remainder of 106.
Record the quotient 1 as the next digit in the result. 
Result so far: 164503.925101
Subtracting 494 from 600 leaves us with 106.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1060, and continue the process.

Advancing to step 15:
If we divide 1060 by 494, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 164503.9251012
Subtracting 988 from 1060 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 16:
If we divide 720 by 494, we get 1 and a remainder of 226.
Write down 1 as next digit of the result. 
Result so far: 164503.92510121
Deduct 494 from 720 and we're left with 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

The final outcome is 164503.92510121, with a leftover of 2.26e-07.
