We're dividing 185970 by 57 
The aim is to understand the frequency of 57 in 185970.

Step 1:
57 goes into 1 0 times with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 57

Going ahead to step 2:
The number 57 fits into 18 0 times, leaving a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 57

Moving on to step 3:
57 goes into 185 3 times with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 171 from 185 to get 14.
Include the next digit (9) from the dividend after 14, then repeat: 149 / 57

Going ahead to step 4:
57 can be fit into 149 2 times, resulting in a remainder of 35.
The next digit of our result is 2. 
Result so far: 32.0
Deduct 114 from 149 and we're left with 35.
Include the next digit (7) from the dividend after 35, then repeat: 357 / 57

Step 5:
When dividing 357 by 57, we get 6 with a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 326.0
If we subtract 342 from 357, we get 15.
Include the next digit (0) from the dividend after 15, then repeat: 150 / 57

Let's proceed to step 6:
The number 57 fits into 150 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 3262.0
The remainder is 36 after subtracting 114 from 150.
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 7:
The number 57 fits into 360 6 times, leaving a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 3262.6
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.

Step 8:
180 divided by 57 is 3 with a remainder of 9.
Use 3 as the next digit of our solution. 
Result so far: 3262.63
The remainder is 9 after subtracting 171 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 9:
57 can be fit into 90 1 times, resulting in a remainder of 33.
The number 1 becomes the next digit in our result. 
Result so far: 3262.631
Subtract 57 from 90 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 10:
57 can be fit into 330 5 times, resulting in a remainder of 45.
The next digit of our result is 5. 
Result so far: 3262.6315
If we subtract 285 from 330, 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.

Going ahead to step 11:
If we divide 450 by 57, we get 7 and a remainder of 51.
The number 7 becomes the next digit in our result. 
Result so far: 3262.63157
Subtracting 399 from 450 leaves us with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

On to step 12:
57 goes into 510 8 times with a remainder of 54.
The number 8 becomes the next digit in our result. 
Result so far: 3262.631578
If we subtract 456 from 510, we 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 13:
540 divided by 57 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 3262.6315789
Subtract 513 from 540 to 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.

Step 14:
When dividing 270 by 57, we get 4 with a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 3262.63157894
Subtract 228 from 270 to get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final outcome is 3262.63157894, with a leftover of 4.2e-08.
