457909 ÷ 43 
The aim is to understand the frequency of 43 in 457909.

Going ahead to step 1:
43 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 43

Going ahead to step 2:
43 goes into 45 1 times with a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 43 from 45 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 43

Advancing to step 3:
27 divided by 43 is 0 with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtract 0 from 27 to get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 43

Moving on to step 4:
When dividing 279 by 43, we get 6 with a remainder of 21.
Write down 6 as next digit of the result. 
Result so far: 106.0
If we take 258 away from 279, we end up with 21.
Bring next digit (0) of the dividend behind the 21 and repeat the process: 210 / 43

Moving on to step 5:
If we divide 210 by 43, we get 4 and a remainder of 38.
The next digit of our result is 4. 
Result so far: 1064.0
Subtract 172 from 210 to get 38.
Append the next digit (9) from the dividend to 38 and continue with: 389 / 43

Step 6:
389 divided by 43 is 9 with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 10649.0
The remainder is 2 after subtracting 387 from 389.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
The number 43 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 10649.0
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.

Going ahead to step 8:
43 goes into 200 4 times with a remainder of 28.
Record the quotient 4 as the next digit in the result. 
Result so far: 10649.04
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.

Step 9:
If we divide 280 by 43, we get 6 and a remainder of 22.
The next digit of our result is 6. 
Result so far: 10649.046
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.

Step 10:
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: 10649.0465
Deduct 215 from 220 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 11:
50 divided by 43 is 1 with a remainder of 7.
Use 1 as the next digit of our solution. 
Result so far: 10649.04651
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.

Going ahead to step 12:
The number 43 fits into 70 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 10649.046511
Subtract 43 from 70 to 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 quotient of the division is 10649.046511, and the remainder is 2.7e-06.
