We look at the division of 819340 by 58 
The aim is to understand the frequency of 58 in 819340.

On to step 1:
58 can be fit into 8 0 times, resulting in a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 58

Going ahead to step 2:
81 divided by 58 is 1 with a remainder of 23.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 58 from 81, we get 23.
Append the next digit (9) from the dividend to 23 and continue with: 239 / 58

Going ahead to step 3:
If we divide 239 by 58, we get 4 and a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we take 232 away from 239, we end up with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 58

On to step 4:
The number 58 fits into 73 1 times, leaving a remainder of 15.
Use 1 as the next digit of our solution. 
Result so far: 141.0
If we take 58 away from 73, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 58

Moving on to step 5:
58 goes into 154 2 times with a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 1412.0
If we take 116 away from 154, we end up with 38.
Include the next digit (0) from the dividend after 38, then repeat: 380 / 58

Let's proceed to step 6:
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: 14126.0
If we take 348 away from 380, we end up 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.

On to step 7:
58 goes into 320 5 times with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 14126.5
The remainder is 30 after subtracting 290 from 320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
300 divided by 58 is 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 14126.55
If we take 290 away from 300, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 14126.55 and a remainder of 0.01.
