405226 ÷ 43 
The aim is to understand the frequency of 43 in 405226.

Step 1:
The number 43 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 43

Moving on to step 2:
43 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 40 after subtracting 0 from 40.
Fetch the next digit (5) from the dividend, attach it to 40 and continue: 405 / 43

Step 3:
43 can be fit into 405 9 times, resulting in a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 387 from 405 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 43

Step 4:
43 goes into 182 4 times with a remainder of 10.
The next digit of our result is 4. 
Result so far: 94.0
Deduct 172 from 182 and we're left with 10.
Include the next digit (2) from the dividend after 10, then repeat: 102 / 43

Step 5:
When dividing 102 by 43, we get 2 with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 942.0
Subtract 86 from 102 to get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 43

Going ahead to step 6:
If we divide 166 by 43, we get 3 and a remainder of 37.
Record the quotient 3 as the next digit in the result. 
Result so far: 9423.0
If we take 129 away from 166, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

On to step 7:
43 goes into 370 8 times with a remainder of 26.
Record the quotient 8 as the next digit in the result. 
Result so far: 9423.8
Deduct 344 from 370 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Going ahead to step 8:
If we divide 260 by 43, we get 6 and a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 9423.86
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 9:
If we divide 20 by 43, we get 0 and a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9423.86
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
If we divide 200 by 43, we get 4 and a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 9423.8604
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.

Going ahead to step 11:
When dividing 280 by 43, we get 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 9423.86046
Deduct 258 from 280 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 12:
43 goes into 220 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 9423.860465
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 13:
When dividing 50 by 43, we get 1 with a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 9423.8604651
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.

Let's proceed to step 14:
The number 43 fits into 70 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 9423.86046511
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 result is 9423.86046511 with a remainder of 2.7e-08.
