90519994 ÷ 495 
The aim is to understand the frequency of 495 in 90519994.

Step 1:
495 goes into 9 0 times with 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.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 495

Going ahead to step 2:
If we divide 90 by 495, we get 0 and a remainder of 90.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 90 and we're left with 90.
Include the next digit (5) from the dividend after 90, then repeat: 905 / 495

Going ahead to step 3:
If we divide 905 by 495, we get 1 and a remainder of 410.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 495 from 905 leaves us with 410.
Fetch the next digit (1) from the dividend, attach it to 410 and continue: 4101 / 495

On to step 4:
4101 divided by 495 is 8 with a remainder of 141.
Write down 8 as next digit of the result. 
Result so far: 18.0
Subtracting 3960 from 4101 leaves us with 141.
Append the next digit (9) from the dividend to 141 and continue with: 1419 / 495

Moving on to step 5:
When dividing 1419 by 495, we get 2 with a remainder of 429.
The number 2 becomes the next digit in our result. 
Result so far: 182.0
If we subtract 990 from 1419, we get 429.
Include the next digit (9) from the dividend after 429, then repeat: 4299 / 495

Advancing to step 6:
495 goes into 4299 8 times with a remainder of 339.
Put 8 as the next digit of the answer. 
Result so far: 1828.0
Deduct 3960 from 4299 and we're left with 339.
Take the next digit (9) from the dividend and append it to 339, then repeat: 3399 / 495

Going ahead to step 7:
495 can be fit into 3399 6 times, resulting in a remainder of 429.
Use 6 as the next digit of our solution. 
Result so far: 18286.0
Deduct 2970 from 3399 and we're left with 429.
Fetch the next digit (4) from the dividend, attach it to 429 and continue: 4294 / 495

Going ahead to step 8:
4294 divided by 495 is 8 with a remainder of 334.
Use 8 as the next digit of our solution. 
Result so far: 182868.0
If we subtract 3960 from 4294, we get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Let's proceed to step 9:
3340 divided by 495 is 6 with a remainder of 370.
Record the quotient 6 as the next digit in the result. 
Result so far: 182868.6
The remainder is 370 after subtracting 2970 from 3340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Going ahead to step 10:
If we divide 3700 by 495, we get 7 and a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 182868.67
If we take 3465 away from 3700, we end up with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Going ahead to step 11:
495 goes into 2350 4 times with a remainder of 370.
Write down 4 as next digit of the result. 
Result so far: 182868.674
Subtracting 1980 from 2350 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 12:
When dividing 3700 by 495, we get 7 with a remainder of 235.
Record the quotient 7 as the next digit in the result. 
Result so far: 182868.6747
Subtracting 3465 from 3700 leaves us with 235.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Advancing to step 13:
The number 495 fits into 2350 4 times, leaving a remainder of 370.
Put 4 as the next digit of the answer. 
Result so far: 182868.67474
Subtracting 1980 from 2350 leaves us with 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Advancing to step 14:
When dividing 3700 by 495, we get 7 with a remainder of 235.
Use 7 as the next digit of our solution. 
Result so far: 182868.674747
The remainder is 235 after subtracting 3465 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

Moving on to step 15:
The number 495 fits into 2350 4 times, leaving a remainder of 370.
Write down 4 as next digit of the result. 
Result so far: 182868.6747474
If we subtract 1980 from 2350, we get 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3700, and continue the process.

Let's proceed to step 16:
When dividing 3700 by 495, we get 7 with a remainder of 235.
The number 7 becomes the next digit in our result. 
Result so far: 182868.67474747
The remainder is 235 after subtracting 3465 from 3700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2350, and continue the process.

The final outcome is 182868.67474747, with a leftover of 2.35e-07.
