We look at the division of 865711 by 58 
The aim is to understand the frequency of 58 in 865711.

On to step 1:
The number 58 fits into 8 0 times, leaving a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 58

Going ahead to step 2:
If we divide 86 by 58, we get 1 and a remainder of 28.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 58 from 86, we get 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 58

On to step 3:
If we divide 285 by 58, we get 4 and a remainder of 53.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 53 after subtracting 232 from 285.
Append the next digit (7) from the dividend to 53 and continue with: 537 / 58

Going ahead to step 4:
The number 58 fits into 537 9 times, leaving a remainder of 15.
Use 9 as the next digit of our solution. 
Result so far: 149.0
If we take 522 away from 537, we end up with 15.
Grab the next digit (1) from the dividend, add it to 15, then carry on: 151 / 58

On to step 5:
151 divided by 58 is 2 with a remainder of 35.
Record the quotient 2 as the next digit in the result. 
Result so far: 1492.0
Deduct 116 from 151 and we're left with 35.
Fetch the next digit (1) from the dividend, attach it to 35 and continue: 351 / 58

Going ahead to step 6:
If we divide 351 by 58, we get 6 and a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 14926.0
If we subtract 348 from 351, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 7:
30 divided by 58 is 0 with a remainder of 30.
The number 0 becomes the next digit in our result. 
Result so far: 14926.0
If we subtract 0 from 30, we get 30.
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.
Use 5 as the next digit of our solution. 
Result so far: 14926.05
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.

Step 9:
58 can be fit into 100 1 times, resulting in a remainder of 42.
The next digit of our result is 1. 
Result so far: 14926.051
The remainder is 42 after subtracting 58 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
58 can be fit into 420 7 times, resulting in a remainder of 14.
The next digit of our result is 7. 
Result so far: 14926.0517
Subtracting 406 from 420 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 11:
58 goes into 140 2 times with a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 14926.05172
If we subtract 116 from 140, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 12:
58 can be fit into 240 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 14926.051724
If we take 232 away from 240, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 13:
When dividing 80 by 58, we get 1 with a remainder of 22.
Record the quotient 1 as the next digit in the result. 
Result so far: 14926.0517241
If we subtract 58 from 80, we 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 14:
58 can be fit into 220 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 14926.05172413
The remainder is 46 after subtracting 174 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The final outcome is 14926.05172413, with a leftover of 4.6e-08.
