We divide 86491004 by 313
We want to figure out the number of times 86491004 can be divided by 313.

Step 1:
313 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 313

Going ahead to step 2:
The number 313 fits into 86 0 times, leaving a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Fetch the next digit (4) from the dividend, attach it to 86 and continue: 864 / 313

Let's proceed to step 3:
313 can be fit into 864 2 times, resulting in a remainder of 238.
Write down 2 as next digit of the result. 
Result so far: 2.0
Subtract 626 from 864 to get 238.
Bring next digit (9) of the dividend behind the 238 and repeat the process: 2389 / 313

Going ahead to step 4:
If we divide 2389 by 313, we get 7 and a remainder of 198.
The next digit of our result is 7. 
Result so far: 27.0
Subtract 2191 from 2389 to get 198.
Include the next digit (1) from the dividend after 198, then repeat: 1981 / 313

Step 5:
313 can be fit into 1981 6 times, resulting in a remainder of 103.
The next digit of our result is 6. 
Result so far: 276.0
The remainder is 103 after subtracting 1878 from 1981.
Bring next digit (0) of the dividend behind the 103 and repeat the process: 1030 / 313

Advancing to step 6:
When dividing 1030 by 313, we get 3 with a remainder of 91.
The next digit of our result is 3. 
Result so far: 2763.0
The remainder is 91 after subtracting 939 from 1030.
Include the next digit (0) from the dividend after 91, then repeat: 910 / 313

On to step 7:
910 divided by 313 is 2 with a remainder of 284.
Use 2 as the next digit of our solution. 
Result so far: 27632.0
The remainder is 284 after subtracting 626 from 910.
Grab the next digit (4) from the dividend, add it to 284, then carry on: 2844 / 313

Advancing to step 8:
If we divide 2844 by 313, we get 9 and a remainder of 27.
Put 9 as the next digit of the answer. 
Result so far: 276329.0
The remainder is 27 after subtracting 2817 from 2844.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 9:
270 divided by 313 is 0 with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 276329.0
Subtracting 0 from 270 leaves us with 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

On to step 10:
313 goes into 2700 8 times with a remainder of 196.
Record the quotient 8 as the next digit in the result. 
Result so far: 276329.08
The remainder is 196 after subtracting 2504 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Going ahead to step 11:
If we divide 1960 by 313, we get 6 and a remainder of 82.
Put 6 as the next digit of the answer. 
Result so far: 276329.086
Subtracting 1878 from 1960 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.

Going ahead to step 12:
If we divide 820 by 313, we get 2 and a remainder of 194.
Use 2 as the next digit of our solution. 
Result so far: 276329.0862
Deduct 626 from 820 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Step 13:
The number 313 fits into 1940 6 times, leaving a remainder of 62.
The next digit of our result is 6. 
Result so far: 276329.08626
If we subtract 1878 from 1940, we get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

On to step 14:
313 goes into 620 1 times with a remainder of 307.
Put 1 as the next digit of the answer. 
Result so far: 276329.086261
Subtracting 313 from 620 leaves us with 307.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3070, and continue the process.

Advancing to step 15:
If we divide 3070 by 313, we get 9 and a remainder of 253.
The next digit of our result is 9. 
Result so far: 276329.0862619
Subtracting 2817 from 3070 leaves us with 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Advancing to step 16:
If we divide 2530 by 313, we get 8 and a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 276329.08626198
Deduct 2504 from 2530 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 276329.08626198, with a leftover of 2.6e-08.
