Let's divide 145486 by 58
The aim is to understand the frequency of 58 in 145486.

Step 1:
The number 58 fits into 1 0 times, leaving a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 58

Advancing to step 2:
14 divided by 58 is 0 with a remainder of 14.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 14 and we're left with 14.
Take the next digit (5) from the dividend and append it to 14, then repeat: 145 / 58

Let's proceed to step 3:
58 can be fit into 145 2 times, resulting in a remainder of 29.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 116 from 145, we get 29.
Append the next digit (4) from the dividend to 29 and continue with: 294 / 58

Moving on to step 4:
When dividing 294 by 58, we get 5 with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 25.0
If we subtract 290 from 294, we get 4.
Include the next digit (8) from the dividend after 4, then repeat: 48 / 58

Let's proceed to step 5:
If we divide 48 by 58, we get 0 and a remainder of 48.
The next digit of our result is 0. 
Result so far: 250.0
Deduct 0 from 48 and we're left with 48.
Bring next digit (6) of the dividend behind the 48 and repeat the process: 486 / 58

Step 6:
The number 58 fits into 486 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 2508.0
If we subtract 464 from 486, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 7:
If we divide 220 by 58, we get 3 and a remainder of 46.
Put 3 as the next digit of the answer. 
Result so far: 2508.3
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
460 divided by 58 is 7 with a remainder of 54.
Put 7 as the next digit of the answer. 
Result so far: 2508.37
The remainder is 54 after subtracting 406 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 9:
540 divided by 58 is 9 with a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 2508.379
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 10:
The number 58 fits into 180 3 times, leaving a remainder of 6.
Put 3 as the next digit of the answer. 
Result so far: 2508.3793
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 11:
If we divide 60 by 58, we get 1 and a remainder of 2.
The next digit of our result is 1. 
Result so far: 2508.37931
If we subtract 58 from 60, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 12:
58 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 2508.37931
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 13:
58 goes into 200 3 times with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 2508.3793103
Deduct 174 from 200 and we're left 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.

Step 14:
When dividing 260 by 58, we get 4 with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 2508.37931034
Subtracting 232 from 260 leaves us 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.

The final result is 2508.37931034 with a remainder of 2.8e-08.
