91173714 ÷ 512 
We want to figure out the number of times 91173714 can be divided by 512.

Let's proceed to step 1:
If we divide 9 by 512, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 512

Let's proceed to step 2:
512 can be fit into 91 0 times, resulting in a remainder of 91.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 91 leaves us with 91.
Include the next digit (1) from the dividend after 91, then repeat: 911 / 512

Step 3:
512 can be fit into 911 1 times, resulting in a remainder of 399.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 399 after subtracting 512 from 911.
Take the next digit (7) from the dividend and append it to 399, then repeat: 3997 / 512

On to step 4:
512 goes into 3997 7 times with a remainder of 413.
The next digit of our result is 7. 
Result so far: 17.0
Subtracting 3584 from 3997 leaves us with 413.
Take the next digit (3) from the dividend and append it to 413, then repeat: 4133 / 512

Let's proceed to step 5:
If we divide 4133 by 512, we get 8 and a remainder of 37.
The next digit of our result is 8. 
Result so far: 178.0
Subtracting 4096 from 4133 leaves us with 37.
Take the next digit (7) from the dividend and append it to 37, then repeat: 377 / 512

Advancing to step 6:
512 goes into 377 0 times with a remainder of 377.
The next digit of our result is 0. 
Result so far: 1780.0
The remainder is 377 after subtracting 0 from 377.
Append the next digit (1) from the dividend to 377 and continue with: 3771 / 512

Moving on to step 7:
When dividing 3771 by 512, we get 7 with a remainder of 187.
Write down 7 as next digit of the result. 
Result so far: 17807.0
Deduct 3584 from 3771 and we're left with 187.
Grab the next digit (4) from the dividend, add it to 187, then carry on: 1874 / 512

Advancing to step 8:
512 can be fit into 1874 3 times, resulting in a remainder of 338.
The next digit of our result is 3. 
Result so far: 178073.0
If we subtract 1536 from 1874, we get 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

On to step 9:
The number 512 fits into 3380 6 times, leaving a remainder of 308.
Use 6 as the next digit of our solution. 
Result so far: 178073.6
If we take 3072 away from 3380, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 10:
When dividing 3080 by 512, we get 6 with a remainder of 8.
The next digit of our result is 6. 
Result so far: 178073.66
The remainder is 8 after subtracting 3072 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 178073.66, and the remainder is 0.008.
