We look at the division of 406579 by 58 
The aim is to understand the frequency of 58 in 406579.

On to step 1:
When dividing 4 by 58, we get 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 58

Step 2:
58 can be fit into 40 0 times, resulting in a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 40, we get 40.
Include the next digit (6) from the dividend after 40, then repeat: 406 / 58

Moving on to step 3:
406 divided by 58 is 7 with a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtract 406 from 406 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 58

Moving on to step 4:
5 divided by 58 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Deduct 0 from 5 and we're left with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 58

Going ahead to step 5:
57 divided by 58 is 0 with a remainder of 57.
Use 0 as the next digit of our solution. 
Result so far: 700.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (9) of the dividend behind the 57 and repeat the process: 579 / 58

Advancing to step 6:
58 can be fit into 579 9 times, resulting in a remainder of 57.
The next digit of our result is 9. 
Result so far: 7009.0
Deduct 522 from 579 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Going ahead to step 7:
58 goes into 570 9 times with a remainder of 48.
The next digit of our result is 9. 
Result so far: 7009.9
Deduct 522 from 570 and we're left 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.

Let's proceed to step 8:
If we divide 480 by 58, we get 8 and a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 7009.98
The remainder is 16 after subtracting 464 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 9:
When dividing 160 by 58, we get 2 with a remainder of 44.
Use 2 as the next digit of our solution. 
Result so far: 7009.982
If we take 116 away from 160, 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.

Moving on to step 10:
58 can be fit into 440 7 times, resulting in a remainder of 34.
Write down 7 as next digit of the result. 
Result so far: 7009.9827
Subtract 406 from 440 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 11:
340 divided by 58 is 5 with a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 7009.98275
If we take 290 away from 340, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 12:
If we divide 500 by 58, we get 8 and a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 7009.982758
If we take 464 away from 500, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 13:
58 can be fit into 360 6 times, resulting in a remainder of 12.
Write down 6 as next digit of the result. 
Result so far: 7009.9827586
Subtract 348 from 360 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 14:
58 goes into 120 2 times with a remainder of 4.
The next digit of our result is 2. 
Result so far: 7009.98275862
If we take 116 away from 120, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 7009.98275862 with a balance of 4e-09.
