We divide 91090514 by 522
We want to figure out the number of times 91090514 can be divided by 522.

On to step 1:
If we divide 9 by 522, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 522

Moving on to step 2:
When dividing 91 by 522, we get 0 with a remainder of 91.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 91, we end up with 91.
Grab the next digit (0) from the dividend, add it to 91, then carry on: 910 / 522

Advancing to step 3:
When dividing 910 by 522, we get 1 with a remainder of 388.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 522 from 910 and we're left with 388.
Take the next digit (9) from the dividend and append it to 388, then repeat: 3889 / 522

Going ahead to step 4:
522 can be fit into 3889 7 times, resulting in a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
Subtracting 3654 from 3889 leaves us with 235.
Grab the next digit (0) from the dividend, add it to 235, then carry on: 2350 / 522

Let's proceed to step 5:
522 goes into 2350 4 times with a remainder of 262.
Write down 4 as next digit of the result. 
Result so far: 174.0
If we subtract 2088 from 2350, we get 262.
Append the next digit (5) from the dividend to 262 and continue with: 2625 / 522

Step 6:
The number 522 fits into 2625 5 times, leaving a remainder of 15.
The next digit of our result is 5. 
Result so far: 1745.0
Subtracting 2610 from 2625 leaves us with 15.
Take the next digit (1) from the dividend and append it to 15, then repeat: 151 / 522

Going ahead to step 7:
522 goes into 151 0 times with a remainder of 151.
Put 0 as the next digit of the answer. 
Result so far: 17450.0
Subtract 0 from 151 to get 151.
Include the next digit (4) from the dividend after 151, then repeat: 1514 / 522

Advancing to step 8:
522 can be fit into 1514 2 times, resulting in a remainder of 470.
Use 2 as the next digit of our solution. 
Result so far: 174502.0
Deduct 1044 from 1514 and we're left with 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4700, and continue the process.

Step 9:
When dividing 4700 by 522, we get 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 174502.9
Subtract 4698 from 4700 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
522 goes into 20 0 times with a remainder of 20.
The next digit of our result is 0. 
Result so far: 174502.9
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
If we divide 200 by 522, we get 0 and a remainder of 200.
Write down 0 as next digit of the result. 
Result so far: 174502.9
Subtracting 0 from 200 leaves us with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 174502.9 with a remaining 0.02.
