358323 divided by 57 
The aim is to understand the frequency of 57 in 358323.

Step 1:
3 divided by 57 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 57

Let's proceed to step 2:
When dividing 35 by 57, we get 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Take the next digit (8) from the dividend and append it to 35, then repeat: 358 / 57

Step 3:
57 goes into 358 6 times with a remainder of 16.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we take 342 away from 358, we end up with 16.
Include the next digit (3) from the dividend after 16, then repeat: 163 / 57

Moving on to step 4:
When dividing 163 by 57, we get 2 with a remainder of 49.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtracting 114 from 163 leaves us with 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 57

Advancing to step 5:
The number 57 fits into 492 8 times, leaving a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 628.0
If we subtract 456 from 492, we get 36.
Append the next digit (3) from the dividend to 36 and continue with: 363 / 57

Going ahead to step 6:
57 can be fit into 363 6 times, resulting in a remainder of 21.
The next digit of our result is 6. 
Result so far: 6286.0
Subtracting 342 from 363 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 7:
The number 57 fits into 210 3 times, leaving a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 6286.3
If we take 171 away from 210, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
If we divide 390 by 57, we get 6 and a remainder of 48.
Record the quotient 6 as the next digit in the result. 
Result so far: 6286.36
Subtracting 342 from 390 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Moving on to step 9:
When dividing 480 by 57, we get 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 6286.368
Subtracting 456 from 480 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 10:
57 goes into 240 4 times with a remainder of 12.
The next digit of our result is 4. 
Result so far: 6286.3684
Subtract 228 from 240 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
If we divide 120 by 57, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 6286.36842
Subtracting 114 from 120 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 12:
If we divide 60 by 57, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 6286.368421
If we subtract 57 from 60, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 13:
The number 57 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 6286.368421
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
The number 57 fits into 300 5 times, leaving a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 6286.36842105
Subtracting 285 from 300 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 6286.36842105 with a remainder of 1.5e-08.
