Let's divide 405550 by 43
The aim is to understand the frequency of 43 in 405550.

Advancing to step 1:
When dividing 4 by 43, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 43

On to step 2:
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: 0.0
If we take 0 away from 40, we end up with 40.
Grab the next digit (5) from the dividend, add it to 40, then carry on: 405 / 43

Let's proceed to step 3:
405 divided by 43 is 9 with a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
If we subtract 387 from 405, we get 18.
Bring next digit (5) of the dividend behind the 18 and repeat the process: 185 / 43

Step 4:
If we divide 185 by 43, we get 4 and a remainder of 13.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
Subtracting 172 from 185 leaves us with 13.
Grab the next digit (5) from the dividend, add it to 13, then carry on: 135 / 43

Let's proceed to step 5:
When dividing 135 by 43, we get 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 943.0
Deduct 129 from 135 and we're left with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 43

Moving on to step 6:
If we divide 60 by 43, we get 1 and a remainder of 17.
The number 1 becomes the next digit in our result. 
Result so far: 9431.0
Subtract 43 from 60 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
If we divide 170 by 43, we get 3 and a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 9431.3
Subtract 129 from 170 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Step 8:
When dividing 410 by 43, we get 9 with a remainder of 23.
Use 9 as the next digit of our solution. 
Result so far: 9431.39
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
When dividing 230 by 43, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 9431.395
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 10:
The number 43 fits into 150 3 times, leaving a remainder of 21.
Record the quotient 3 as the next digit in the result. 
Result so far: 9431.3953
If we take 129 away from 150, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 11:
When dividing 210 by 43, we get 4 with a remainder of 38.
The number 4 becomes the next digit in our result. 
Result so far: 9431.39534
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 12:
43 goes into 380 8 times with a remainder of 36.
Record the quotient 8 as the next digit in the result. 
Result so far: 9431.395348
If we take 344 away from 380, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
43 can be fit into 360 8 times, resulting in a remainder of 16.
Put 8 as the next digit of the answer. 
Result so far: 9431.3953488
Deduct 344 from 360 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 9431.3953488, with a leftover of 1.6e-07.
