506001 ÷ 43 
The aim is to understand the frequency of 43 in 506001.

Advancing to step 1:
The number 43 fits into 5 0 times, leaving a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (0) from the dividend and append it to 5, then repeat: 50 / 43

Moving on to step 2:
The number 43 fits into 50 1 times, leaving a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 50 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 43

Going ahead to step 3:
If we divide 76 by 43, we get 1 and a remainder of 33.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 43 from 76 to get 33.
Grab the next digit (0) from the dividend, add it to 33, then carry on: 330 / 43

Going ahead to step 4:
43 can be fit into 330 7 times, resulting in a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 117.0
If we take 301 away from 330, we end up with 29.
Grab the next digit (0) from the dividend, add it to 29, then carry on: 290 / 43

Moving on to step 5:
When dividing 290 by 43, we get 6 with a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1176.0
The remainder is 32 after subtracting 258 from 290.
Grab the next digit (1) from the dividend, add it to 32, then carry on: 321 / 43

Let's proceed to step 6:
43 goes into 321 7 times with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 11767.0
Deduct 301 from 321 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 7:
200 divided by 43 is 4 with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 11767.4
Subtracting 172 from 200 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.

On to step 8:
43 can be fit into 280 6 times, resulting in a remainder of 22.
The number 6 becomes the next digit in our result. 
Result so far: 11767.46
The remainder is 22 after subtracting 258 from 280.
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 9:
When dividing 220 by 43, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 11767.465
The remainder is 5 after subtracting 215 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 10:
When dividing 50 by 43, we get 1 with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 11767.4651
If we take 43 away from 50, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 11:
The number 43 fits into 70 1 times, leaving a remainder of 27.
The number 1 becomes the next digit in our result. 
Result so far: 11767.46511
If we subtract 43 from 70, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

The final outcome is 11767.46511, with a leftover of 2.7e-05.
