We look at the division of 13040496 by 285 
The aim is to understand the frequency of 285 in 13040496.

Let's proceed to step 1:
285 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Include the next digit (3) from the dividend after 1, then repeat: 13 / 285

Moving on to step 2:
13 divided by 285 is 0 with a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 13, we get 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 285

Advancing to step 3:
When dividing 130 by 285, we get 0 with a remainder of 130.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 130 to get 130.
Fetch the next digit (4) from the dividend, attach it to 130 and continue: 1304 / 285

On to step 4:
285 goes into 1304 4 times with a remainder of 164.
The next digit of our result is 4. 
Result so far: 4.0
If we subtract 1140 from 1304, we get 164.
Fetch the next digit (0) from the dividend, attach it to 164 and continue: 1640 / 285

Let's proceed to step 5:
If we divide 1640 by 285, we get 5 and a remainder of 215.
Use 5 as the next digit of our solution. 
Result so far: 45.0
The remainder is 215 after subtracting 1425 from 1640.
Grab the next digit (4) from the dividend, add it to 215, then carry on: 2154 / 285

Let's proceed to step 6:
The number 285 fits into 2154 7 times, leaving a remainder of 159.
Put 7 as the next digit of the answer. 
Result so far: 457.0
Subtracting 1995 from 2154 leaves us with 159.
Append the next digit (9) from the dividend to 159 and continue with: 1599 / 285

Going ahead to step 7:
285 can be fit into 1599 5 times, resulting in a remainder of 174.
Use 5 as the next digit of our solution. 
Result so far: 4575.0
Subtracting 1425 from 1599 leaves us with 174.
Bring next digit (6) of the dividend behind the 174 and repeat the process: 1746 / 285

Let's proceed to step 8:
285 goes into 1746 6 times with a remainder of 36.
Write down 6 as next digit of the result. 
Result so far: 45756.0
Subtracting 1710 from 1746 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 9:
If we divide 360 by 285, we get 1 and a remainder of 75.
The number 1 becomes the next digit in our result. 
Result so far: 45756.1
If we take 285 away from 360, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 10:
When dividing 750 by 285, we get 2 with a remainder of 180.
Write down 2 as next digit of the result. 
Result so far: 45756.12
The remainder is 180 after subtracting 570 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

Advancing to step 11:
The number 285 fits into 1800 6 times, leaving a remainder of 90.
The next digit of our result is 6. 
Result so far: 45756.126
If we subtract 1710 from 1800, we get 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Going ahead to step 12:
285 goes into 900 3 times with a remainder of 45.
The next digit of our result is 3. 
Result so far: 45756.1263
If we subtract 855 from 900, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
285 can be fit into 450 1 times, resulting in a remainder of 165.
The next digit of our result is 1. 
Result so far: 45756.12631
Subtracting 285 from 450 leaves us with 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

On to step 14:
285 goes into 1650 5 times with a remainder of 225.
The next digit of our result is 5. 
Result so far: 45756.126315
Subtracting 1425 from 1650 leaves us with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

Advancing to step 15:
2250 divided by 285 is 7 with a remainder of 255.
Record the quotient 7 as the next digit in the result. 
Result so far: 45756.1263157
If we take 1995 away from 2250, we end up with 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Going ahead to step 16:
If we divide 2550 by 285, we get 8 and a remainder of 270.
Use 8 as the next digit of our solution. 
Result so far: 45756.12631578
The remainder is 270 after subtracting 2280 from 2550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2700, and continue the process.

Our division results in 45756.12631578 with a remaining 2.7e-07.
