We look at the division of 389545 by 58 
The aim is to understand the frequency of 58 in 389545.

Step 1:
When dividing 3 by 58, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 58

Advancing to step 2:
If we divide 38 by 58, we get 0 and a remainder of 38.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 38 leaves us with 38.
Fetch the next digit (9) from the dividend, attach it to 38 and continue: 389 / 58

Going ahead to step 3:
389 divided by 58 is 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 348 from 389, we get 41.
Take the next digit (5) from the dividend and append it to 41, then repeat: 415 / 58

Going ahead to step 4:
58 goes into 415 7 times with a remainder of 9.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Subtract 406 from 415 to get 9.
Grab the next digit (4) from the dividend, add it to 9, then carry on: 94 / 58

On to step 5:
58 goes into 94 1 times with a remainder of 36.
The next digit of our result is 1. 
Result so far: 671.0
Subtracting 58 from 94 leaves us with 36.
Include the next digit (5) from the dividend after 36, then repeat: 365 / 58

Let's proceed to step 6:
58 can be fit into 365 6 times, resulting in a remainder of 17.
Use 6 as the next digit of our solution. 
Result so far: 6716.0
Subtracting 348 from 365 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
When dividing 170 by 58, we get 2 with a remainder of 54.
Put 2 as the next digit of the answer. 
Result so far: 6716.2
Subtract 116 from 170 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Going ahead to step 8:
58 goes into 540 9 times with a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 6716.29
If we subtract 522 from 540, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 58 is 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 6716.293
If we subtract 174 from 180, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 10:
58 goes into 60 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 6716.2931
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.

Moving on to step 11:
58 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 6716.2931
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 12:
58 can be fit into 200 3 times, resulting in a remainder of 26.
The next digit of our result is 3. 
Result so far: 6716.293103
If we take 174 away from 200, 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 13:
58 goes into 260 4 times with a remainder of 28.
Put 4 as the next digit of the answer. 
Result so far: 6716.2931034
If we subtract 232 from 260, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

On to step 14:
When dividing 280 by 58, we get 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 6716.29310344
If we take 232 away from 280, we end up 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 outcome is 6716.29310344, with a leftover of 4.8e-08.
