Let's divide 943970 by 58
The aim is to understand the frequency of 58 in 943970.

Step 1:
If we divide 9 by 58, we get 0 and a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Include the next digit (4) from the dividend after 9, then repeat: 94 / 58

Let's proceed to step 2:
When dividing 94 by 58, we get 1 with a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 58 away from 94, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 58

Moving on to step 3:
If we divide 363 by 58, we get 6 and a remainder of 15.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 348 from 363 leaves us with 15.
Fetch the next digit (9) from the dividend, attach it to 15 and continue: 159 / 58

Moving on to step 4:
The number 58 fits into 159 2 times, leaving a remainder of 43.
Put 2 as the next digit of the answer. 
Result so far: 162.0
The remainder is 43 after subtracting 116 from 159.
Bring next digit (7) of the dividend behind the 43 and repeat the process: 437 / 58

Moving on to step 5:
437 divided by 58 is 7 with a remainder of 31.
Record the quotient 7 as the next digit in the result. 
Result so far: 1627.0
Deduct 406 from 437 and we're left with 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 58

Let's proceed to step 6:
58 goes into 310 5 times with a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 16275.0
If we subtract 290 from 310, 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.

Going ahead to step 7:
When dividing 200 by 58, we get 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 16275.3
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.

Advancing to step 8:
When dividing 260 by 58, we get 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 16275.34
Subtract 232 from 260 to get 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 9:
280 divided by 58 is 4 with a remainder of 48.
The next digit of our result is 4. 
Result so far: 16275.344
The remainder is 48 after subtracting 232 from 280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

After the division, we end up with 16275.344 and a remainder of 0.0048.
