We divide 579715 by 43
The aim is to understand the frequency of 43 in 579715.

Moving on to step 1:
5 divided by 43 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 43

Advancing to step 2:
If we divide 57 by 43, we get 1 and a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 43 from 57 to get 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 43

Let's proceed to step 3:
43 can be fit into 149 3 times, resulting in a remainder of 20.
Write down 3 as next digit of the result. 
Result so far: 13.0
If we subtract 129 from 149, we get 20.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 43

Going ahead to step 4:
The number 43 fits into 207 4 times, leaving a remainder of 35.
Put 4 as the next digit of the answer. 
Result so far: 134.0
Deduct 172 from 207 and we're left with 35.
Take the next digit (1) from the dividend and append it to 35, then repeat: 351 / 43

Let's proceed to step 5:
351 divided by 43 is 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 1348.0
Subtracting 344 from 351 leaves us with 7.
Fetch the next digit (5) from the dividend, attach it to 7 and continue: 75 / 43

Step 6:
75 divided by 43 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 13481.0
Subtracting 43 from 75 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Advancing to step 7:
The number 43 fits into 320 7 times, leaving a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 13481.7
Subtract 301 from 320 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 8:
43 can be fit into 190 4 times, resulting in a remainder of 18.
Record the quotient 4 as the next digit in the result. 
Result so far: 13481.74
Subtracting 172 from 190 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 43 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 13481.744
If we subtract 172 from 180, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 13481.744, and the remainder is 0.0008.
