We look at the division of 557430 by 58 
The aim is to understand the frequency of 58 in 557430.

Moving on to step 1:
When dividing 5 by 58, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 58

On to step 2:
The number 58 fits into 55 0 times, leaving a remainder of 55.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (7) from the dividend and append it to 55, then repeat: 557 / 58

Moving on to step 3:
The number 58 fits into 557 9 times, leaving a remainder of 35.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 522 from 557 and we're left with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 58

Step 4:
The number 58 fits into 354 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 96.0
The remainder is 6 after subtracting 348 from 354.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 58

Advancing to step 5:
When dividing 63 by 58, we get 1 with a remainder of 5.
The next digit of our result is 1. 
Result so far: 961.0
The remainder is 5 after subtracting 58 from 63.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 58

Step 6:
58 goes into 50 0 times with a remainder of 50.
Use 0 as the next digit of our solution. 
Result so far: 9610.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 7:
500 divided by 58 is 8 with a remainder of 36.
Use 8 as the next digit of our solution. 
Result so far: 9610.8
Subtract 464 from 500 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 8:
If we divide 360 by 58, we get 6 and a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 9610.86
If we take 348 away from 360, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 9:
120 divided by 58 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 9610.862
Subtract 116 from 120 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 10:
The number 58 fits into 40 0 times, leaving a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9610.862
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 11:
58 goes into 400 6 times with a remainder of 52.
Put 6 as the next digit of the answer. 
Result so far: 9610.86206
If we take 348 away from 400, 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.

On to step 12:
When dividing 520 by 58, we get 8 with a remainder of 56.
Write down 8 as next digit of the result. 
Result so far: 9610.862068
Subtract 464 from 520 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 13:
When dividing 560 by 58, we get 9 with a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 9610.8620689
If we subtract 522 from 560, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 14:
When dividing 380 by 58, we get 6 with a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 9610.86206896
Subtracting 348 from 380 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The final outcome is 9610.86206896, with a leftover of 3.2e-08.
