258004 divided by 43 
The aim is to understand the frequency of 43 in 258004.

On to step 1:
If we divide 2 by 43, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 43

On to step 2:
When dividing 25 by 43, we get 0 with a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 43

Step 3:
The number 43 fits into 258 6 times, leaving a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we subtract 258 from 258, we get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 43

Let's proceed to step 4:
43 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 60.0
If we take 0 away from 0, we end up with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 43

Going ahead to step 5:
43 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 600.0
The remainder is 0 after subtracting 0 from 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 43

Going ahead to step 6:
43 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 6000.0
Subtracting 0 from 4 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.

On to step 7:
The number 43 fits into 40 0 times, leaving a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 6000.0
If we take 0 away from 40, we end up 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.

Going ahead to step 8:
The number 43 fits into 400 9 times, leaving a remainder of 13.
Write down 9 as next digit of the result. 
Result so far: 6000.09
Deduct 387 from 400 and we're left with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 9:
The number 43 fits into 130 3 times, leaving a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 6000.093
Subtract 129 from 130 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
43 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 6000.093
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 11:
43 can be fit into 100 2 times, resulting in a remainder of 14.
Record the quotient 2 as the next digit in the result. 
Result so far: 6000.09302
Deduct 86 from 100 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 12:
43 can be fit into 140 3 times, resulting in a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 6000.093023
If we subtract 129 from 140, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 13:
110 divided by 43 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 6000.0930232
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 14:
43 can be fit into 240 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 6000.09302325
Subtracting 215 from 240 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Our division results in 6000.09302325 with a remaining 2.5e-08.
