We look at the division of 723515 by 58 
The aim is to understand the frequency of 58 in 723515.

Going ahead to step 1:
The number 58 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 58

On to step 2:
The number 58 fits into 72 1 times, leaving a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 58 from 72 to get 14.
Fetch the next digit (3) from the dividend, attach it to 14 and continue: 143 / 58

On to step 3:
If we divide 143 by 58, we get 2 and a remainder of 27.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 116 from 143 leaves us with 27.
Bring next digit (5) of the dividend behind the 27 and repeat the process: 275 / 58

Step 4:
When dividing 275 by 58, we get 4 with a remainder of 43.
Write down 4 as next digit of the result. 
Result so far: 124.0
If we take 232 away from 275, we end up with 43.
Take the next digit (1) from the dividend and append it to 43, then repeat: 431 / 58

Going ahead to step 5:
58 can be fit into 431 7 times, resulting in a remainder of 25.
Record the quotient 7 as the next digit in the result. 
Result so far: 1247.0
The remainder is 25 after subtracting 406 from 431.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 58

Going ahead to step 6:
58 goes into 255 4 times with a remainder of 23.
Put 4 as the next digit of the answer. 
Result so far: 12474.0
Deduct 232 from 255 and we're left with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 7:
If we divide 230 by 58, we get 3 and a remainder of 56.
The next digit of our result is 3. 
Result so far: 12474.3
Subtract 174 from 230 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
58 goes into 560 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 12474.39
Subtracting 522 from 560 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Step 9:
58 can be fit into 380 6 times, resulting in a remainder of 32.
Put 6 as the next digit of the answer. 
Result so far: 12474.396
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 10:
If we divide 320 by 58, we get 5 and a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 12474.3965
If we subtract 290 from 320, 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.

Going ahead to step 11:
58 goes into 300 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 12474.39655
If we subtract 290 from 300, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 12474.39655 with a balance of 1e-05.
