We look at the division of 15789135 by 495 
The aim is to understand the frequency of 495 in 15789135.

Let's proceed to step 1:
495 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 495

Let's proceed to step 2:
If we divide 15 by 495, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 15 to get 15.
Bring next digit (7) of the dividend behind the 15 and repeat the process: 157 / 495

On to step 3:
495 can be fit into 157 0 times, resulting in a remainder of 157.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 157 and we're left with 157.
Append the next digit (8) from the dividend to 157 and continue with: 1578 / 495

On to step 4:
495 can be fit into 1578 3 times, resulting in a remainder of 93.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 93 after subtracting 1485 from 1578.
Fetch the next digit (9) from the dividend, attach it to 93 and continue: 939 / 495

On to step 5:
495 goes into 939 1 times with a remainder of 444.
The next digit of our result is 1. 
Result so far: 31.0
Deduct 495 from 939 and we're left with 444.
Grab the next digit (1) from the dividend, add it to 444, then carry on: 4441 / 495

On to step 6:
The number 495 fits into 4441 8 times, leaving a remainder of 481.
The next digit of our result is 8. 
Result so far: 318.0
Deduct 3960 from 4441 and we're left with 481.
Fetch the next digit (3) from the dividend, attach it to 481 and continue: 4813 / 495

Step 7:
495 goes into 4813 9 times with a remainder of 358.
Put 9 as the next digit of the answer. 
Result so far: 3189.0
Deduct 4455 from 4813 and we're left with 358.
Take the next digit (5) from the dividend and append it to 358, then repeat: 3585 / 495

Step 8:
The number 495 fits into 3585 7 times, leaving a remainder of 120.
Record the quotient 7 as the next digit in the result. 
Result so far: 31897.0
Subtracting 3465 from 3585 leaves us with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 9:
495 can be fit into 1200 2 times, resulting in a remainder of 210.
Write down 2 as next digit of the result. 
Result so far: 31897.2
If we subtract 990 from 1200, we get 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 10:
If we divide 2100 by 495, we get 4 and a remainder of 120.
The next digit of our result is 4. 
Result so far: 31897.24
Subtract 1980 from 2100 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Moving on to step 11:
The number 495 fits into 1200 2 times, leaving a remainder of 210.
The number 2 becomes the next digit in our result. 
Result so far: 31897.242
Deduct 990 from 1200 and we're left with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

Going ahead to step 12:
495 goes into 2100 4 times with a remainder of 120.
Record the quotient 4 as the next digit in the result. 
Result so far: 31897.2424
If we subtract 1980 from 2100, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 13:
495 can be fit into 1200 2 times, resulting in a remainder of 210.
Record the quotient 2 as the next digit in the result. 
Result so far: 31897.24242
If we take 990 away from 1200, we end up with 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 14:
If we divide 2100 by 495, we get 4 and a remainder of 120.
The next digit of our result is 4. 
Result so far: 31897.242424
If we take 1980 away from 2100, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Step 15:
When dividing 1200 by 495, we get 2 with a remainder of 210.
The next digit of our result is 2. 
Result so far: 31897.2424242
The remainder is 210 after subtracting 990 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2100, and continue the process.

On to step 16:
The number 495 fits into 2100 4 times, leaving a remainder of 120.
Put 4 as the next digit of the answer. 
Result so far: 31897.24242424
Subtract 1980 from 2100 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

After the division, we end up with 31897.24242424 and a remainder of 1.2e-07.
