573036 divided by 57 
The aim is to understand the frequency of 57 in 573036.

On to step 1:
If we divide 5 by 57, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 57

Moving on to step 2:
If we divide 57 by 57, we get 1 and a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 57 from 57 to get 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 57

Step 3:
If we divide 3 by 57, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 57

Advancing to step 4:
When dividing 30 by 57, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 100.0
Deduct 0 from 30 and we're left with 30.
Bring next digit (3) of the dividend behind the 30 and repeat the process: 303 / 57

Step 5:
If we divide 303 by 57, we get 5 and a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 1005.0
Deduct 285 from 303 and we're left with 18.
Include the next digit (6) from the dividend after 18, then repeat: 186 / 57

On to step 6:
186 divided by 57 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 10053.0
Subtract 171 from 186 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 7:
When dividing 150 by 57, we get 2 with a remainder of 36.
Use 2 as the next digit of our solution. 
Result so far: 10053.2
Subtracting 114 from 150 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.

Let's proceed to step 8:
If we divide 360 by 57, we get 6 and a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 10053.26
If we subtract 342 from 360, we get 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:
The number 57 fits into 180 3 times, leaving a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 10053.263
If we subtract 171 from 180, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 10:
57 can be fit into 90 1 times, resulting in a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 10053.2631
The remainder is 33 after subtracting 57 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 11:
57 can be fit into 330 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 10053.26315
The remainder is 45 after subtracting 285 from 330.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
450 divided by 57 is 7 with a remainder of 51.
The next digit of our result is 7. 
Result so far: 10053.263157
The remainder is 51 after subtracting 399 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 13:
57 goes into 510 8 times with a remainder of 54.
The next digit of our result is 8. 
Result so far: 10053.2631578
Subtract 456 from 510 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 14:
If we divide 540 by 57, we get 9 and a remainder of 27.
Write down 9 as next digit of the result. 
Result so far: 10053.26315789
If we subtract 513 from 540, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

In conclusion, the division gives 10053.26315789 with a balance of 2.7e-08.
