579906 divided by 58 
The aim is to understand the frequency of 58 in 579906.

Step 1:
58 goes into 5 0 times with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Fetch the next digit (7) from the dividend, attach it to 5 and continue: 57 / 58

Going ahead to step 2:
58 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Grab the next digit (9) from the dividend, add it to 57, then carry on: 579 / 58

On to step 3:
58 goes into 579 9 times with a remainder of 57.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 522 from 579, we get 57.
Include the next digit (9) from the dividend after 57, then repeat: 579 / 58

Going ahead to step 4:
If we divide 579 by 58, we get 9 and a remainder of 57.
Put 9 as the next digit of the answer. 
Result so far: 99.0
If we subtract 522 from 579, we get 57.
Fetch the next digit (0) from the dividend, attach it to 57 and continue: 570 / 58

Going ahead to step 5:
If we divide 570 by 58, we get 9 and a remainder of 48.
Record the quotient 9 as the next digit in the result. 
Result so far: 999.0
Deduct 522 from 570 and we're left with 48.
Take the next digit (6) from the dividend and append it to 48, then repeat: 486 / 58

Step 6:
If we divide 486 by 58, we get 8 and a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 9998.0
Subtract 464 from 486 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.

Going ahead to step 7:
When dividing 220 by 58, we get 3 with a remainder of 46.
Record the quotient 3 as the next digit in the result. 
Result so far: 9998.3
Deduct 174 from 220 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
If we divide 460 by 58, we get 7 and a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 9998.37
The remainder is 54 after subtracting 406 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
The number 58 fits into 540 9 times, leaving a remainder of 18.
Put 9 as the next digit of the answer. 
Result so far: 9998.379
The remainder is 18 after subtracting 522 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Moving on to step 10:
180 divided by 58 is 3 with a remainder of 6.
Write down 3 as next digit of the result. 
Result so far: 9998.3793
The remainder is 6 after subtracting 174 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 11:
If we divide 60 by 58, we get 1 and a remainder of 2.
The number 1 becomes the next digit in our result. 
Result so far: 9998.37931
Subtracting 58 from 60 leaves us 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.

On to step 12:
58 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 9998.37931
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 13:
58 goes into 200 3 times with a remainder of 26.
Put 3 as the next digit of the answer. 
Result so far: 9998.3793103
If we subtract 174 from 200, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 14:
58 can be fit into 260 4 times, resulting in a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 9998.37931034
Subtracting 232 from 260 leaves us 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.

After the division, we end up with 9998.37931034 and a remainder of 2.8e-08.
