91809995 ÷ 495 
The aim is to understand the frequency of 495 in 91809995.

On to step 1:
When dividing 9 by 495, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 495

Let's proceed to step 2:
The number 495 fits into 91 0 times, leaving a remainder of 91.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 91 and we're left with 91.
Bring next digit (8) of the dividend behind the 91 and repeat the process: 918 / 495

Moving on to step 3:
The number 495 fits into 918 1 times, leaving a remainder of 423.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 495 from 918, we get 423.
Fetch the next digit (0) from the dividend, attach it to 423 and continue: 4230 / 495

Let's proceed to step 4:
When dividing 4230 by 495, we get 8 with a remainder of 270.
Put 8 as the next digit of the answer. 
Result so far: 18.0
The remainder is 270 after subtracting 3960 from 4230.
Fetch the next digit (9) from the dividend, attach it to 270 and continue: 2709 / 495

Advancing to step 5:
The number 495 fits into 2709 5 times, leaving a remainder of 234.
Put 5 as the next digit of the answer. 
Result so far: 185.0
If we subtract 2475 from 2709, we get 234.
Take the next digit (9) from the dividend and append it to 234, then repeat: 2349 / 495

Step 6:
2349 divided by 495 is 4 with a remainder of 369.
Write down 4 as next digit of the result. 
Result so far: 1854.0
The remainder is 369 after subtracting 1980 from 2349.
Take the next digit (9) from the dividend and append it to 369, then repeat: 3699 / 495

Going ahead to step 7:
The number 495 fits into 3699 7 times, leaving a remainder of 234.
The next digit of our result is 7. 
Result so far: 18547.0
Subtracting 3465 from 3699 leaves us with 234.
Append the next digit (5) from the dividend to 234 and continue with: 2345 / 495

Let's proceed to step 8:
2345 divided by 495 is 4 with a remainder of 365.
Write down 4 as next digit of the result. 
Result so far: 185474.0
If we take 1980 away from 2345, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Let's proceed to step 9:
3650 divided by 495 is 7 with a remainder of 185.
Use 7 as the next digit of our solution. 
Result so far: 185474.7
Subtracting 3465 from 3650 leaves us with 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Moving on to step 10:
495 goes into 1850 3 times with a remainder of 365.
The next digit of our result is 3. 
Result so far: 185474.73
If we take 1485 away from 1850, we end up with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 11:
If we divide 3650 by 495, we get 7 and a remainder of 185.
The number 7 becomes the next digit in our result. 
Result so far: 185474.737
Subtract 3465 from 3650 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Let's proceed to step 12:
The number 495 fits into 1850 3 times, leaving a remainder of 365.
Use 3 as the next digit of our solution. 
Result so far: 185474.7373
If we subtract 1485 from 1850, we get 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 13:
The number 495 fits into 3650 7 times, leaving a remainder of 185.
The next digit of our result is 7. 
Result so far: 185474.73737
Subtract 3465 from 3650 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 14:
1850 divided by 495 is 3 with a remainder of 365.
Write down 3 as next digit of the result. 
Result so far: 185474.737373
Subtracting 1485 from 1850 leaves us with 365.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

On to step 15:
495 goes into 3650 7 times with a remainder of 185.
Record the quotient 7 as the next digit in the result. 
Result so far: 185474.7373737
Subtract 3465 from 3650 to get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Advancing to step 16:
1850 divided by 495 is 3 with a remainder of 365.
Put 3 as the next digit of the answer. 
Result so far: 185474.73737373
The remainder is 365 after subtracting 1485 from 1850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3650, and continue the process.

Our division results in 185474.73737373 with a remaining 3.65e-07.
