We look at the division of 647829 by 43 
The aim is to understand the frequency of 43 in 647829.

On to step 1:
When dividing 6 by 43, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 43

Step 2:
64 divided by 43 is 1 with a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 43 from 64, we get 21.
Include the next digit (7) from the dividend after 21, then repeat: 217 / 43

Going ahead to step 3:
If we divide 217 by 43, we get 5 and a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 15.0
If we subtract 215 from 217, we get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 43

Going ahead to step 4:
The number 43 fits into 28 0 times, leaving a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 150.0
Subtracting 0 from 28 leaves us with 28.
Take the next digit (2) from the dividend and append it to 28, then repeat: 282 / 43

Let's proceed to step 5:
43 can be fit into 282 6 times, resulting in a remainder of 24.
The next digit of our result is 6. 
Result so far: 1506.0
The remainder is 24 after subtracting 258 from 282.
Bring next digit (9) of the dividend behind the 24 and repeat the process: 249 / 43

On to step 6:
249 divided by 43 is 5 with a remainder of 34.
The number 5 becomes the next digit in our result. 
Result so far: 15065.0
Deduct 215 from 249 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 7:
If we divide 340 by 43, we get 7 and a remainder of 39.
The next digit of our result is 7. 
Result so far: 15065.7
If we take 301 away from 340, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 8:
43 goes into 390 9 times with a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 15065.79
If we take 387 away from 390, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 9:
When dividing 30 by 43, we get 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 15065.79
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 10:
When dividing 300 by 43, we get 6 with a remainder of 42.
The number 6 becomes the next digit in our result. 
Result so far: 15065.7906
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
43 goes into 420 9 times with a remainder of 33.
Write down 9 as next digit of the result. 
Result so far: 15065.79069
Subtracting 387 from 420 leaves us with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 12:
330 divided by 43 is 7 with a remainder of 29.
The next digit of our result is 7. 
Result so far: 15065.790697
Subtract 301 from 330 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 13:
43 goes into 290 6 times with a remainder of 32.
The next digit of our result is 6. 
Result so far: 15065.7906976
Subtracting 258 from 290 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.

Moving on to step 14:
When dividing 320 by 43, we get 7 with a remainder of 19.
Write down 7 as next digit of the result. 
Result so far: 15065.79069767
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.

The quotient of the division is 15065.79069767, and the remainder is 1.9e-08.
