We're dividing 435943 by 58 
The aim is to understand the frequency of 58 in 435943.

Going ahead to step 1:
The number 58 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 58

Let's proceed to step 2:
58 can be fit into 43 0 times, resulting in a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 43 leaves us with 43.
Append the next digit (5) from the dividend to 43 and continue with: 435 / 58

Moving on to step 3:
58 goes into 435 7 times with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 7.0
The remainder is 29 after subtracting 406 from 435.
Append the next digit (9) from the dividend to 29 and continue with: 299 / 58

Let's proceed to step 4:
The number 58 fits into 299 5 times, leaving a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 75.0
If we subtract 290 from 299, we get 9.
Append the next digit (4) from the dividend to 9 and continue with: 94 / 58

Moving on to step 5:
58 can be fit into 94 1 times, resulting in a remainder of 36.
The number 1 becomes the next digit in our result. 
Result so far: 751.0
Deduct 58 from 94 and we're left with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 58

On to step 6:
If we divide 363 by 58, we get 6 and a remainder of 15.
The number 6 becomes the next digit in our result. 
Result so far: 7516.0
Subtracting 348 from 363 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 58, we get 2 with a remainder of 34.
Put 2 as the next digit of the answer. 
Result so far: 7516.2
If we take 116 away from 150, we end up with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
340 divided by 58 is 5 with a remainder of 50.
The next digit of our result is 5. 
Result so far: 7516.25
If we take 290 away from 340, we end up with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 9:
58 goes into 500 8 times with a remainder of 36.
Put 8 as the next digit of the answer. 
Result so far: 7516.258
The remainder is 36 after subtracting 464 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 10:
The number 58 fits into 360 6 times, leaving a remainder of 12.
Record the quotient 6 as the next digit in the result. 
Result so far: 7516.2586
If we subtract 348 from 360, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
If we divide 120 by 58, we get 2 and a remainder of 4.
The next digit of our result is 2. 
Result so far: 7516.25862
Subtracting 116 from 120 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 12:
40 divided by 58 is 0 with a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 7516.25862
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 13:
If we divide 400 by 58, we get 6 and a remainder of 52.
Write down 6 as next digit of the result. 
Result so far: 7516.2586206
Subtracting 348 from 400 leaves us with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 14:
The number 58 fits into 520 8 times, leaving a remainder of 56.
Put 8 as the next digit of the answer. 
Result so far: 7516.25862068
The remainder is 56 after subtracting 464 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

In conclusion, the division gives 7516.25862068 with a balance of 5.6e-08.
