290393 ÷ 58 
The aim is to understand the frequency of 58 in 290393.

Going ahead to step 1:
The number 58 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Append the next digit (9) from the dividend to 2 and continue with: 29 / 58

Advancing to step 2:
29 divided by 58 is 0 with a remainder of 29.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 29 leaves us with 29.
Bring next digit (0) of the dividend behind the 29 and repeat the process: 290 / 58

Moving on to step 3:
If we divide 290 by 58, we get 5 and a remainder of 0.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 290 from 290, we get 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 58

On to step 4:
58 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
Subtract 0 from 3 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 58

Let's proceed to step 5:
When dividing 39 by 58, we get 0 with a remainder of 39.
The next digit of our result is 0. 
Result so far: 500.0
If we subtract 0 from 39, we get 39.
Append the next digit (3) from the dividend to 39 and continue with: 393 / 58

Moving on to step 6:
When dividing 393 by 58, we get 6 with a remainder of 45.
The number 6 becomes the next digit in our result. 
Result so far: 5006.0
Subtracting 348 from 393 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

On to step 7:
58 goes into 450 7 times with a remainder of 44.
The next digit of our result is 7. 
Result so far: 5006.7
If we take 406 away from 450, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 58 fits into 440 7 times, leaving a remainder of 34.
Put 7 as the next digit of the answer. 
Result so far: 5006.77
Subtracting 406 from 440 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

The final result is 5006.77 with a remainder of 0.034.
