We're dividing 528001 by 43 
The aim is to understand the frequency of 43 in 528001.

Moving on to step 1:
43 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 43

On to step 2:
The number 43 fits into 52 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 43 from 52, we get 9.
Grab the next digit (8) from the dividend, add it to 9, then carry on: 98 / 43

Advancing to step 3:
98 divided by 43 is 2 with a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Subtract 86 from 98 to get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 43

On to step 4:
The number 43 fits into 120 2 times, leaving a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 122.0
If we subtract 86 from 120, we get 34.
Grab the next digit (0) from the dividend, add it to 34, then carry on: 340 / 43

Advancing to step 5:
If we divide 340 by 43, we get 7 and a remainder of 39.
The number 7 becomes the next digit in our result. 
Result so far: 1227.0
Subtracting 301 from 340 leaves us with 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 43

Step 6:
If we divide 391 by 43, we get 9 and a remainder of 4.
Write down 9 as next digit of the result. 
Result so far: 12279.0
The remainder is 4 after subtracting 387 from 391.
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:
43 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12279.0
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.

Let's proceed to step 8:
When dividing 400 by 43, we get 9 with a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 12279.09
Subtracting 387 from 400 leaves us 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.

Step 9:
43 can be fit into 130 3 times, resulting in a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 12279.093
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 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12279.093
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.

Let's proceed to step 11:
If we divide 100 by 43, we get 2 and a remainder of 14.
The next digit of our result is 2. 
Result so far: 12279.09302
The remainder is 14 after subtracting 86 from 100.
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 next digit of our result is 3. 
Result so far: 12279.093023
Deduct 129 from 140 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 13:
The number 43 fits into 110 2 times, leaving a remainder of 24.
The next digit of our result is 2. 
Result so far: 12279.0930232
If we take 86 away from 110, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 14:
240 divided by 43 is 5 with a remainder of 25.
The next digit of our result is 5. 
Result so far: 12279.09302325
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 12279.09302325 with a remaining 2.5e-08.
