We divide 859440 by 43
The aim is to understand the frequency of 43 in 859440.

Going ahead to step 1:
The number 43 fits into 8 0 times, leaving a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (5) from the dividend, add it to 8, then carry on: 85 / 43

Moving on to step 2:
When dividing 85 by 43, we get 1 with a remainder of 42.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 43 from 85, we get 42.
Take the next digit (9) from the dividend and append it to 42, then repeat: 429 / 43

Going ahead to step 3:
43 goes into 429 9 times with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 19.0
Subtract 387 from 429 to get 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 43

Moving on to step 4:
The number 43 fits into 424 9 times, leaving a remainder of 37.
The next digit of our result is 9. 
Result so far: 199.0
The remainder is 37 after subtracting 387 from 424.
Append the next digit (4) from the dividend to 37 and continue with: 374 / 43

Moving on to step 5:
The number 43 fits into 374 8 times, leaving a remainder of 30.
The next digit of our result is 8. 
Result so far: 1998.0
If we take 344 away from 374, we end up with 30.
Grab the next digit (0) from the dividend, add it to 30, then carry on: 300 / 43

Advancing to step 6:
The number 43 fits into 300 6 times, leaving a remainder of 42.
Record the quotient 6 as the next digit in the result. 
Result so far: 19986.0
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 7:
43 can be fit into 420 9 times, resulting in a remainder of 33.
Use 9 as the next digit of our solution. 
Result so far: 19986.9
If we take 387 away from 420, we end up 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 8:
43 can be fit into 330 7 times, resulting in a remainder of 29.
Write down 7 as next digit of the result. 
Result so far: 19986.97
If we take 301 away from 330, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Advancing to step 9:
290 divided by 43 is 6 with a remainder of 32.
Write down 6 as next digit of the result. 
Result so far: 19986.976
If we take 258 away from 290, we end up 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.

Let's proceed to step 10:
The number 43 fits into 320 7 times, leaving a remainder of 19.
The next digit of our result is 7. 
Result so far: 19986.9767
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.

On to step 11:
If we divide 190 by 43, we get 4 and a remainder of 18.
The number 4 becomes the next digit in our result. 
Result so far: 19986.97674
Subtract 172 from 190 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 12:
The number 43 fits into 180 4 times, leaving a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 19986.976744
If we take 172 away from 180, we end up with 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 final outcome is 19986.976744, with a leftover of 8e-07.
