We look at the division of 572872 by 58 
The aim is to understand the frequency of 58 in 572872.

Step 1:
If we divide 5 by 58, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 58

Moving on to step 2:
57 divided by 58 is 0 with a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Bring next digit (2) of the dividend behind the 57 and repeat the process: 572 / 58

Going ahead to step 3:
58 can be fit into 572 9 times, resulting in a remainder of 50.
The next digit of our result is 9. 
Result so far: 9.0
The remainder is 50 after subtracting 522 from 572.
Grab the next digit (8) from the dividend, add it to 50, then carry on: 508 / 58

Step 4:
58 can be fit into 508 8 times, resulting in a remainder of 44.
Record the quotient 8 as the next digit in the result. 
Result so far: 98.0
If we subtract 464 from 508, we get 44.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 58

Advancing to step 5:
58 can be fit into 447 7 times, resulting in a remainder of 41.
The next digit of our result is 7. 
Result so far: 987.0
Deduct 406 from 447 and we're left with 41.
Include the next digit (2) from the dividend after 41, then repeat: 412 / 58

Step 6:
The number 58 fits into 412 7 times, leaving a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 9877.0
If we subtract 406 from 412, 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 7:
60 divided by 58 is 1 with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 9877.1
If we take 58 away from 60, we end up with 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 8:
The number 58 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 9877.1
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.

Let's proceed to step 9:
58 can be fit into 200 3 times, resulting in a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 9877.103
The remainder is 26 after subtracting 174 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
The number 58 fits into 260 4 times, leaving a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 9877.1034
Deduct 232 from 260 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 11:
58 goes into 280 4 times with a remainder of 48.
Use 4 as the next digit of our solution. 
Result so far: 9877.10344
Subtracting 232 from 280 leaves us 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 result is 9877.10344 with a remainder of 4.8e-05.
