We look at the division of 345907 by 58 
The aim is to understand the frequency of 58 in 345907.

Moving on to step 1:
If we divide 3 by 58, we get 0 and a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 58

Going ahead to step 2:
When dividing 34 by 58, we get 0 with a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (5) of the dividend behind the 34 and repeat the process: 345 / 58

Advancing to step 3:
If we divide 345 by 58, we get 5 and a remainder of 55.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 290 from 345 to get 55.
Include the next digit (9) from the dividend after 55, then repeat: 559 / 58

Step 4:
58 can be fit into 559 9 times, resulting in a remainder of 37.
The next digit of our result is 9. 
Result so far: 59.0
Subtract 522 from 559 to get 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 58

Step 5:
The number 58 fits into 370 6 times, leaving a remainder of 22.
Record the quotient 6 as the next digit in the result. 
Result so far: 596.0
If we take 348 away from 370, we end up with 22.
Append the next digit (7) from the dividend to 22 and continue with: 227 / 58

On to step 6:
When dividing 227 by 58, we get 3 with a remainder of 53.
The number 3 becomes the next digit in our result. 
Result so far: 5963.0
If we subtract 174 from 227, we get 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 7:
58 goes into 530 9 times with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 5963.9
If we subtract 522 from 530, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 8:
58 goes into 80 1 times with a remainder of 22.
Put 1 as the next digit of the answer. 
Result so far: 5963.91
Subtract 58 from 80 to 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.

Step 9:
If we divide 220 by 58, we get 3 and a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 5963.913
Subtract 174 from 220 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Moving on to step 10:
If we divide 460 by 58, we get 7 and a remainder of 54.
Use 7 as the next digit of our solution. 
Result so far: 5963.9137
Deduct 406 from 460 and we're left with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Advancing to step 11:
540 divided by 58 is 9 with a remainder of 18.
The next digit of our result is 9. 
Result so far: 5963.91379
Subtracting 522 from 540 leaves us with 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 12:
The number 58 fits into 180 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 5963.913793
Subtract 174 from 180 to 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 13:
58 goes into 60 1 times with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 5963.9137931
The remainder is 2 after subtracting 58 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 14:
The number 58 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 5963.9137931
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.

The final outcome is 5963.9137931, with a leftover of 2e-08.
