We look at the division of 729608 by 58 
The aim is to understand the frequency of 58 in 729608.

Let's proceed to step 1:
When dividing 7 by 58, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 58

Advancing to step 2:
When dividing 72 by 58, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 14 after subtracting 58 from 72.
Bring next digit (9) of the dividend behind the 14 and repeat the process: 149 / 58

Advancing to step 3:
If we divide 149 by 58, we get 2 and a remainder of 33.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 116 from 149 leaves us with 33.
Append the next digit (6) from the dividend to 33 and continue with: 336 / 58

Advancing to step 4:
The number 58 fits into 336 5 times, leaving a remainder of 46.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
If we subtract 290 from 336, we get 46.
Bring next digit (0) of the dividend behind the 46 and repeat the process: 460 / 58

On to step 5:
When dividing 460 by 58, we get 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 1257.0
If we take 406 away from 460, we end up with 54.
Include the next digit (8) from the dividend after 54, then repeat: 548 / 58

Advancing to step 6:
58 goes into 548 9 times with a remainder of 26.
Record the quotient 9 as the next digit in the result. 
Result so far: 12579.0
If we take 522 away from 548, 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.

On to step 7:
When dividing 260 by 58, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 12579.4
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.

Advancing to step 8:
When dividing 280 by 58, we get 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 12579.44
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 quotient of the division is 12579.44, and the remainder is 0.048.
