We look at the division of 97785031 by 576 
The aim is to understand the frequency of 576 in 97785031.

On to step 1:
If we divide 9 by 576, we get 0 and a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 576

Advancing to step 2:
97 divided by 576 is 0 with 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.
Bring next digit (7) of the dividend behind the 97 and repeat the process: 977 / 576

Going ahead to step 3:
The number 576 fits into 977 1 times, leaving a remainder of 401.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Deduct 576 from 977 and we're left with 401.
Include the next digit (8) from the dividend after 401, then repeat: 4018 / 576

Going ahead to step 4:
If we divide 4018 by 576, we get 6 and a remainder of 562.
The next digit of our result is 6. 
Result so far: 16.0
If we subtract 3456 from 4018, we get 562.
Append the next digit (5) from the dividend to 562 and continue with: 5625 / 576

On to step 5:
576 can be fit into 5625 9 times, resulting in a remainder of 441.
Record the quotient 9 as the next digit in the result. 
Result so far: 169.0
Subtracting 5184 from 5625 leaves us with 441.
Take the next digit (0) from the dividend and append it to 441, then repeat: 4410 / 576

Let's proceed to step 6:
The number 576 fits into 4410 7 times, leaving a remainder of 378.
Use 7 as the next digit of our solution. 
Result so far: 1697.0
The remainder is 378 after subtracting 4032 from 4410.
Fetch the next digit (3) from the dividend, attach it to 378 and continue: 3783 / 576

Advancing to step 7:
3783 divided by 576 is 6 with a remainder of 327.
Use 6 as the next digit of our solution. 
Result so far: 16976.0
The remainder is 327 after subtracting 3456 from 3783.
Bring next digit (1) of the dividend behind the 327 and repeat the process: 3271 / 576

Moving on to step 8:
If we divide 3271 by 576, we get 5 and a remainder of 391.
The number 5 becomes the next digit in our result. 
Result so far: 169765.0
Subtract 2880 from 3271 to get 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3910, and continue the process.

Let's proceed to step 9:
If we divide 3910 by 576, we get 6 and a remainder of 454.
The number 6 becomes the next digit in our result. 
Result so far: 169765.6
If we subtract 3456 from 3910, we get 454.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 10:
576 can be fit into 4540 7 times, resulting in a remainder of 508.
Write down 7 as next digit of the result. 
Result so far: 169765.67
Deduct 4032 from 4540 and we're left with 508.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5080, and continue the process.

Going ahead to step 11:
If we divide 5080 by 576, we get 8 and a remainder of 472.
Record the quotient 8 as the next digit in the result. 
Result so far: 169765.678
If we subtract 4608 from 5080, we get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

On to step 12:
When dividing 4720 by 576, we get 8 with a remainder of 112.
The number 8 becomes the next digit in our result. 
Result so far: 169765.6788
Subtract 4608 from 4720 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

The final outcome is 169765.6788, with a leftover of 0.00112.
