524559 ÷ 43 
The aim is to understand the frequency of 43 in 524559.

Step 1:
43 can be fit into 5 0 times, resulting in a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 43

Moving on to step 2:
When dividing 52 by 43, we get 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 43 from 52 leaves us with 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 43

On to step 3:
94 divided by 43 is 2 with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 12.0
Deduct 86 from 94 and we're left with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 43

Advancing to step 4:
When dividing 85 by 43, we get 1 with a remainder of 42.
Use 1 as the next digit of our solution. 
Result so far: 121.0
Subtracting 43 from 85 leaves us with 42.
Bring next digit (5) of the dividend behind the 42 and repeat the process: 425 / 43

On to step 5:
The number 43 fits into 425 9 times, leaving a remainder of 38.
Use 9 as the next digit of our solution. 
Result so far: 1219.0
If we take 387 away from 425, we end up with 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 43

Let's proceed to step 6:
If we divide 389 by 43, we get 9 and a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 12199.0
Subtracting 387 from 389 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
If we divide 20 by 43, we get 0 and a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 12199.0
Deduct 0 from 20 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 8:
200 divided by 43 is 4 with a remainder of 28.
The number 4 becomes the next digit in our result. 
Result so far: 12199.04
Subtract 172 from 200 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 9:
280 divided by 43 is 6 with a remainder of 22.
The next digit of our result is 6. 
Result so far: 12199.046
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 10:
43 can be fit into 220 5 times, resulting in a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12199.0465
Subtract 215 from 220 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 11:
The number 43 fits into 50 1 times, leaving a remainder of 7.
The next digit of our result is 1. 
Result so far: 12199.04651
Deduct 43 from 50 and we're left 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.

Going ahead to step 12:
43 goes into 70 1 times with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 12199.046511
Subtracting 43 from 70 leaves us with 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 quotient of the division is 12199.046511, and the remainder is 2.7e-06.
