We're dividing 742310 by 58 
The aim is to understand the frequency of 58 in 742310.

Step 1:
If we divide 7 by 58, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (4) from the dividend after 7, then repeat: 74 / 58

Advancing to step 2:
58 goes into 74 1 times with a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 58 from 74 to get 16.
Fetch the next digit (2) from the dividend, attach it to 16 and continue: 162 / 58

Going ahead to step 3:
The number 58 fits into 162 2 times, leaving a remainder of 46.
The next digit of our result is 2. 
Result so far: 12.0
If we take 116 away from 162, we end up with 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 58

Let's proceed to step 4:
463 divided by 58 is 7 with a remainder of 57.
The next digit of our result is 7. 
Result so far: 127.0
Subtract 406 from 463 to get 57.
Take the next digit (1) from the dividend and append it to 57, then repeat: 571 / 58

Moving on to step 5:
When dividing 571 by 58, we get 9 with a remainder of 49.
The number 9 becomes the next digit in our result. 
Result so far: 1279.0
If we subtract 522 from 571, we get 49.
Fetch the next digit (0) from the dividend, attach it to 49 and continue: 490 / 58

Step 6:
When dividing 490 by 58, we get 8 with a remainder of 26.
Write down 8 as next digit of the result. 
Result so far: 12798.0
If we take 464 away from 490, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 7:
The number 58 fits into 260 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 12798.4
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 8:
58 can be fit into 280 4 times, resulting in a remainder of 48.
Put 4 as the next digit of the answer. 
Result so far: 12798.44
Subtracting 232 from 280 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.

The final result is 12798.44 with a remainder of 0.048.
