730412 divided by 43 
The aim is to understand the frequency of 43 in 730412.

Going ahead to step 1:
When dividing 7 by 43, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 43

Advancing to step 2:
43 goes into 73 1 times with a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 43 away from 73, we end up with 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 43

Moving on to step 3:
43 can be fit into 300 6 times, resulting in a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 16.0
Subtracting 258 from 300 leaves us with 42.
Bring next digit (4) of the dividend behind the 42 and repeat the process: 424 / 43

Advancing to step 4:
If we divide 424 by 43, we get 9 and a remainder of 37.
Use 9 as the next digit of our solution. 
Result so far: 169.0
Subtracting 387 from 424 leaves us with 37.
Fetch the next digit (1) from the dividend, attach it to 37 and continue: 371 / 43

Advancing to step 5:
The number 43 fits into 371 8 times, leaving a remainder of 27.
Record the quotient 8 as the next digit in the result. 
Result so far: 1698.0
The remainder is 27 after subtracting 344 from 371.
Grab the next digit (2) from the dividend, add it to 27, then carry on: 272 / 43

On to step 6:
The number 43 fits into 272 6 times, leaving a remainder of 14.
The next digit of our result is 6. 
Result so far: 16986.0
If we take 258 away from 272, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 7:
If we divide 140 by 43, we get 3 and a remainder of 11.
The number 3 becomes the next digit in our result. 
Result so far: 16986.3
If we take 129 away from 140, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 8:
43 can be fit into 110 2 times, resulting in a remainder of 24.
Record the quotient 2 as the next digit in the result. 
Result so far: 16986.32
If we subtract 86 from 110, we get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
43 can be fit into 240 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 16986.325
If we subtract 215 from 240, we get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

On to step 10:
If we divide 250 by 43, we get 5 and a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 16986.3255
Subtract 215 from 250 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The quotient of the division is 16986.3255, and the remainder is 0.00035.
