90878306 ÷ 318 
Let's see how many times 318 fits into 90878306.

Step 1:
318 can be fit into 9 0 times, resulting in a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 318

Let's proceed to step 2:
If we divide 90 by 318, we get 0 and a remainder of 90.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 90 to get 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 318

Step 3:
318 can be fit into 908 2 times, resulting in a remainder of 272.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 636 from 908 to get 272.
Fetch the next digit (7) from the dividend, attach it to 272 and continue: 2727 / 318

Let's proceed to step 4:
When dividing 2727 by 318, we get 8 with a remainder of 183.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
If we subtract 2544 from 2727, we get 183.
Fetch the next digit (8) from the dividend, attach it to 183 and continue: 1838 / 318

Advancing to step 5:
The number 318 fits into 1838 5 times, leaving a remainder of 248.
Write down 5 as next digit of the result. 
Result so far: 285.0
Subtracting 1590 from 1838 leaves us with 248.
Fetch the next digit (3) from the dividend, attach it to 248 and continue: 2483 / 318

Advancing to step 6:
318 goes into 2483 7 times with a remainder of 257.
Write down 7 as next digit of the result. 
Result so far: 2857.0
If we take 2226 away from 2483, we end up with 257.
Grab the next digit (0) from the dividend, add it to 257, then carry on: 2570 / 318

Step 7:
The number 318 fits into 2570 8 times, leaving a remainder of 26.
The next digit of our result is 8. 
Result so far: 28578.0
Deduct 2544 from 2570 and we're left with 26.
Bring next digit (6) of the dividend behind the 26 and repeat the process: 266 / 318

On to step 8:
When dividing 266 by 318, we get 0 with a remainder of 266.
The number 0 becomes the next digit in our result. 
Result so far: 285780.0
Subtract 0 from 266 to get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 9:
If we divide 2660 by 318, we get 8 and a remainder of 116.
Use 8 as the next digit of our solution. 
Result so far: 285780.8
Subtract 2544 from 2660 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Let's proceed to step 10:
When dividing 1160 by 318, we get 3 with a remainder of 206.
The next digit of our result is 3. 
Result so far: 285780.83
If we take 954 away from 1160, we end up with 206.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2060, and continue the process.

Advancing to step 11:
318 goes into 2060 6 times with a remainder of 152.
The next digit of our result is 6. 
Result so far: 285780.836
If we take 1908 away from 2060, we end up with 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

On to step 12:
318 goes into 1520 4 times with a remainder of 248.
Record the quotient 4 as the next digit in the result. 
Result so far: 285780.8364
If we subtract 1272 from 1520, we get 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Moving on to step 13:
2480 divided by 318 is 7 with a remainder of 254.
The next digit of our result is 7. 
Result so far: 285780.83647
Subtract 2226 from 2480 to get 254.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2540, and continue the process.

Advancing to step 14:
The number 318 fits into 2540 7 times, leaving a remainder of 314.
Write down 7 as next digit of the result. 
Result so far: 285780.836477
Subtract 2226 from 2540 to get 314.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3140, and continue the process.

The final outcome is 285780.836477, with a leftover of 3.14e-05.
