We're dividing 590230 by 57 
The aim is to understand the frequency of 57 in 590230.

Step 1:
57 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (9) from the dividend, attach it to 5 and continue: 59 / 57

Step 2:
The number 57 fits into 59 1 times, leaving a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 57 from 59 and we're left with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 57

Step 3:
When dividing 20 by 57, we get 0 with a remainder of 20.
The next digit of our result is 0. 
Result so far: 10.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (2) from the dividend and append it to 20, then repeat: 202 / 57

Moving on to step 4:
57 can be fit into 202 3 times, resulting in a remainder of 31.
Record the quotient 3 as the next digit in the result. 
Result so far: 103.0
Deduct 171 from 202 and we're left with 31.
Include the next digit (3) from the dividend after 31, then repeat: 313 / 57

Moving on to step 5:
The number 57 fits into 313 5 times, leaving a remainder of 28.
The next digit of our result is 5. 
Result so far: 1035.0
If we subtract 285 from 313, we get 28.
Take the next digit (0) from the dividend and append it to 28, then repeat: 280 / 57

Going ahead to step 6:
The number 57 fits into 280 4 times, leaving a remainder of 52.
Record the quotient 4 as the next digit in the result. 
Result so far: 10354.0
If we take 228 away from 280, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Advancing to step 7:
If we divide 520 by 57, we get 9 and a remainder of 7.
The number 9 becomes the next digit in our result. 
Result so far: 10354.9
Subtracting 513 from 520 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 8:
When dividing 70 by 57, we get 1 with a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 10354.91
Subtract 57 from 70 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 9:
If we divide 130 by 57, we get 2 and a remainder of 16.
The next digit of our result is 2. 
Result so far: 10354.912
Subtracting 114 from 130 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
If we divide 160 by 57, we get 2 and a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 10354.9122
If we take 114 away from 160, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Our division results in 10354.9122 with a remaining 0.00046.
