We're dividing 90966253 by 317 
We want to figure out the number of times 90966253 can be divided by 317.

Step 1:
When dividing 9 by 317, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 317

Let's proceed to step 2:
90 divided by 317 is 0 with a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 90 after subtracting 0 from 90.
Grab the next digit (9) from the dividend, add it to 90, then carry on: 909 / 317

Moving on to step 3:
When dividing 909 by 317, we get 2 with a remainder of 275.
The next digit of our result is 2. 
Result so far: 2.0
If we take 634 away from 909, we end up with 275.
Bring next digit (6) of the dividend behind the 275 and repeat the process: 2756 / 317

On to step 4:
The number 317 fits into 2756 8 times, leaving a remainder of 220.
Write down 8 as next digit of the result. 
Result so far: 28.0
If we take 2536 away from 2756, we end up with 220.
Append the next digit (6) from the dividend to 220 and continue with: 2206 / 317

Advancing to step 5:
When dividing 2206 by 317, we get 6 with a remainder of 304.
The next digit of our result is 6. 
Result so far: 286.0
If we take 1902 away from 2206, we end up with 304.
Include the next digit (2) from the dividend after 304, then repeat: 3042 / 317

Let's proceed to step 6:
317 can be fit into 3042 9 times, resulting in a remainder of 189.
Write down 9 as next digit of the result. 
Result so far: 2869.0
Subtracting 2853 from 3042 leaves us with 189.
Bring next digit (5) of the dividend behind the 189 and repeat the process: 1895 / 317

Let's proceed to step 7:
317 can be fit into 1895 5 times, resulting in a remainder of 310.
Use 5 as the next digit of our solution. 
Result so far: 28695.0
The remainder is 310 after subtracting 1585 from 1895.
Fetch the next digit (3) from the dividend, attach it to 310 and continue: 3103 / 317

Step 8:
3103 divided by 317 is 9 with a remainder of 250.
Write down 9 as next digit of the result. 
Result so far: 286959.0
Subtracting 2853 from 3103 leaves us with 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2500, and continue the process.

Let's proceed to step 9:
When dividing 2500 by 317, we get 7 with a remainder of 281.
Put 7 as the next digit of the answer. 
Result so far: 286959.7
Deduct 2219 from 2500 and we're left with 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2810, and continue the process.

Step 10:
The number 317 fits into 2810 8 times, leaving a remainder of 274.
The number 8 becomes the next digit in our result. 
Result so far: 286959.78
If we take 2536 away from 2810, we end up with 274.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2740, and continue the process.

Step 11:
If we divide 2740 by 317, we get 8 and a remainder of 204.
The next digit of our result is 8. 
Result so far: 286959.788
Subtract 2536 from 2740 to get 204.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

The final outcome is 286959.788, with a leftover of 0.0204.
