320969 divided by 43 
The aim is to understand the frequency of 43 in 320969.

On to step 1:
3 divided by 43 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (2) from the dividend to 3 and continue with: 32 / 43

Advancing to step 2:
If we divide 32 by 43, we get 0 and a remainder of 32.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 32 to get 32.
Append the next digit (0) from the dividend to 32 and continue with: 320 / 43

On to step 3:
When dividing 320 by 43, we get 7 with a remainder of 19.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 301 from 320 and we're left with 19.
Take the next digit (9) from the dividend and append it to 19, then repeat: 199 / 43

Going ahead to step 4:
43 goes into 199 4 times with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 74.0
If we subtract 172 from 199, we get 27.
Grab the next digit (6) from the dividend, add it to 27, then carry on: 276 / 43

Step 5:
When dividing 276 by 43, we get 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 746.0
Subtracting 258 from 276 leaves us with 18.
Take the next digit (9) from the dividend and append it to 18, then repeat: 189 / 43

Step 6:
If we divide 189 by 43, we get 4 and a remainder of 17.
Write down 4 as next digit of the result. 
Result so far: 7464.0
If we subtract 172 from 189, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 7:
43 goes into 170 3 times with a remainder of 41.
Write down 3 as next digit of the result. 
Result so far: 7464.3
Subtracting 129 from 170 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
410 divided by 43 is 9 with a remainder of 23.
Record the quotient 9 as the next digit in the result. 
Result so far: 7464.39
Subtracting 387 from 410 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 9:
230 divided by 43 is 5 with a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 7464.395
The remainder is 15 after subtracting 215 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 10:
150 divided by 43 is 3 with a remainder of 21.
Write down 3 as next digit of the result. 
Result so far: 7464.3953
If we subtract 129 from 150, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 11:
When dividing 210 by 43, we get 4 with a remainder of 38.
The next digit of our result is 4. 
Result so far: 7464.39534
Deduct 172 from 210 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
The number 43 fits into 380 8 times, leaving a remainder of 36.
Write down 8 as next digit of the result. 
Result so far: 7464.395348
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 13:
360 divided by 43 is 8 with a remainder of 16.
Write down 8 as next digit of the result. 
Result so far: 7464.3953488
Subtracting 344 from 360 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

After the division, we end up with 7464.3953488 and a remainder of 1.6e-07.
