We divide 289987 by 43
The aim is to understand the frequency of 43 in 289987.

On to step 1:
When dividing 2 by 43, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 43

Step 2:
28 divided by 43 is 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 28 leaves us with 28.
Append the next digit (9) from the dividend to 28 and continue with: 289 / 43

Moving on to step 3:
289 divided by 43 is 6 with a remainder of 31.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Deduct 258 from 289 and we're left with 31.
Grab the next digit (9) from the dividend, add it to 31, then carry on: 319 / 43

Advancing to step 4:
319 divided by 43 is 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 67.0
Deduct 301 from 319 and we're left with 18.
Append the next digit (8) from the dividend to 18 and continue with: 188 / 43

Let's proceed to step 5:
43 can be fit into 188 4 times, resulting in a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 674.0
Deduct 172 from 188 and we're left with 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 43

Advancing to step 6:
When dividing 167 by 43, we get 3 with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 6743.0
Subtracting 129 from 167 leaves us 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.

Going ahead to step 7:
43 goes into 380 8 times with a remainder of 36.
The number 8 becomes the next digit in our result. 
Result so far: 6743.8
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 8:
43 goes into 360 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 6743.88
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final outcome is 6743.88, with a leftover of 0.016.
