Let's divide 97944543 by 285
The aim is to understand the frequency of 285 in 97944543.

Moving on to step 1:
If we divide 9 by 285, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 285

Advancing to step 2:
285 can be fit into 97 0 times, resulting in a remainder of 97.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 97 leaves us with 97.
Grab the next digit (9) from the dividend, add it to 97, then carry on: 979 / 285

Going ahead to step 3:
979 divided by 285 is 3 with a remainder of 124.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we take 855 away from 979, we end up with 124.
Include the next digit (4) from the dividend after 124, then repeat: 1244 / 285

Step 4:
If we divide 1244 by 285, we get 4 and a remainder of 104.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 1140 from 1244, we get 104.
Include the next digit (4) from the dividend after 104, then repeat: 1044 / 285

Advancing to step 5:
When dividing 1044 by 285, we get 3 with a remainder of 189.
Put 3 as the next digit of the answer. 
Result so far: 343.0
Subtracting 855 from 1044 leaves us with 189.
Take the next digit (5) from the dividend and append it to 189, then repeat: 1895 / 285

Advancing to step 6:
1895 divided by 285 is 6 with a remainder of 185.
Use 6 as the next digit of our solution. 
Result so far: 3436.0
If we subtract 1710 from 1895, we get 185.
Bring next digit (4) of the dividend behind the 185 and repeat the process: 1854 / 285

Let's proceed to step 7:
285 can be fit into 1854 6 times, resulting in a remainder of 144.
The number 6 becomes the next digit in our result. 
Result so far: 34366.0
Subtract 1710 from 1854 to get 144.
Fetch the next digit (3) from the dividend, attach it to 144 and continue: 1443 / 285

Advancing to step 8:
When dividing 1443 by 285, we get 5 with a remainder of 18.
Use 5 as the next digit of our solution. 
Result so far: 343665.0
Deduct 1425 from 1443 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 9:
If we divide 180 by 285, we get 0 and a remainder of 180.
The next digit of our result is 0. 
Result so far: 343665.0
The remainder is 180 after subtracting 0 from 180.
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 10:
When dividing 1800 by 285, we get 6 with a remainder of 90.
Use 6 as the next digit of our solution. 
Result so far: 343665.06
The remainder is 90 after subtracting 1710 from 1800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

On to step 11:
900 divided by 285 is 3 with a remainder of 45.
The next digit of our result is 3. 
Result so far: 343665.063
If we take 855 away from 900, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 12:
The number 285 fits into 450 1 times, leaving a remainder of 165.
Record the quotient 1 as the next digit in the result. 
Result so far: 343665.0631
Subtract 285 from 450 to get 165.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Advancing to step 13:
When dividing 1650 by 285, we get 5 with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 343665.06315
Deduct 1425 from 1650 and we're left 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.

Let's proceed to step 14:
285 can be fit into 2250 7 times, resulting in a remainder of 255.
The next digit of our result is 7. 
Result so far: 343665.063157
Subtract 1995 from 2250 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 15:
The number 285 fits into 2550 8 times, leaving a remainder of 270.
The next digit of our result is 8. 
Result so far: 343665.0631578
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.

Moving on to step 16:
285 goes into 2700 9 times with a remainder of 135.
Use 9 as the next digit of our solution. 
Result so far: 343665.06315789
The remainder is 135 after subtracting 2565 from 2700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1350, and continue the process.

After the division, we end up with 343665.06315789 and a remainder of 1.35e-07.
