We look at the division of 64548611 by 285 
The aim is to understand the frequency of 285 in 64548611.

Moving on to step 1:
285 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (4) from the dividend to 6 and continue with: 64 / 285

Moving on to step 2:
285 goes into 64 0 times with a remainder of 64.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 64 and we're left with 64.
Bring next digit (5) of the dividend behind the 64 and repeat the process: 645 / 285

Advancing to step 3:
645 divided by 285 is 2 with a remainder of 75.
The next digit of our result is 2. 
Result so far: 2.0
Subtract 570 from 645 to get 75.
Fetch the next digit (4) from the dividend, attach it to 75 and continue: 754 / 285

Step 4:
When dividing 754 by 285, we get 2 with a remainder of 184.
The number 2 becomes the next digit in our result. 
Result so far: 22.0
Subtract 570 from 754 to get 184.
Take the next digit (8) from the dividend and append it to 184, then repeat: 1848 / 285

Step 5:
1848 divided by 285 is 6 with a remainder of 138.
Record the quotient 6 as the next digit in the result. 
Result so far: 226.0
Deduct 1710 from 1848 and we're left with 138.
Take the next digit (6) from the dividend and append it to 138, then repeat: 1386 / 285

Moving on to step 6:
If we divide 1386 by 285, we get 4 and a remainder of 246.
The number 4 becomes the next digit in our result. 
Result so far: 2264.0
Deduct 1140 from 1386 and we're left with 246.
Fetch the next digit (1) from the dividend, attach it to 246 and continue: 2461 / 285

On to step 7:
When dividing 2461 by 285, we get 8 with a remainder of 181.
Record the quotient 8 as the next digit in the result. 
Result so far: 22648.0
Subtracting 2280 from 2461 leaves us with 181.
Include the next digit (1) from the dividend after 181, then repeat: 1811 / 285

Advancing to step 8:
285 goes into 1811 6 times with a remainder of 101.
Write down 6 as next digit of the result. 
Result so far: 226486.0
The remainder is 101 after subtracting 1710 from 1811.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Going ahead to step 9:
If we divide 1010 by 285, we get 3 and a remainder of 155.
The number 3 becomes the next digit in our result. 
Result so far: 226486.3
If we subtract 855 from 1010, we get 155.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1550, and continue the process.

Let's proceed to step 10:
285 goes into 1550 5 times with a remainder of 125.
The next digit of our result is 5. 
Result so far: 226486.35
Subtract 1425 from 1550 to get 125.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1250, and continue the process.

Let's proceed to step 11:
285 can be fit into 1250 4 times, resulting in a remainder of 110.
Record the quotient 4 as the next digit in the result. 
Result so far: 226486.354
The remainder is 110 after subtracting 1140 from 1250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1100, and continue the process.

On to step 12:
If we divide 1100 by 285, we get 3 and a remainder of 245.
Record the quotient 3 as the next digit in the result. 
Result so far: 226486.3543
If we subtract 855 from 1100, we get 245.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2450, and continue the process.

On to step 13:
285 can be fit into 2450 8 times, resulting in a remainder of 170.
The number 8 becomes the next digit in our result. 
Result so far: 226486.35438
Subtracting 2280 from 2450 leaves us with 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1700, and continue the process.

On to step 14:
The number 285 fits into 1700 5 times, leaving a remainder of 275.
The next digit of our result is 5. 
Result so far: 226486.354385
Subtracting 1425 from 1700 leaves us with 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

Moving on to step 15:
2750 divided by 285 is 9 with a remainder of 185.
The next digit of our result is 9. 
Result so far: 226486.3543859
Subtracting 2565 from 2750 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.

Step 16:
285 goes into 1850 6 times with a remainder of 140.
Record the quotient 6 as the next digit in the result. 
Result so far: 226486.35438596
Deduct 1710 from 1850 and we're left with 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1400, and continue the process.

The final result is 226486.35438596 with a remainder of 1.4e-07.
