Let's divide 403439 by 89
The aim is to understand the frequency of 89 in 403439.

Moving on to step 1:
89 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 89

Advancing to step 2:
40 divided by 89 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Take the next digit (3) from the dividend and append it to 40, then repeat: 403 / 89

Step 3:
89 can be fit into 403 4 times, resulting in a remainder of 47.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 356 from 403 to get 47.
Include the next digit (4) from the dividend after 47, then repeat: 474 / 89

Let's proceed to step 4:
When dividing 474 by 89, we get 5 with a remainder of 29.
The next digit of our result is 5. 
Result so far: 45.0
Subtracting 445 from 474 leaves us with 29.
Fetch the next digit (3) from the dividend, attach it to 29 and continue: 293 / 89

Moving on to step 5:
293 divided by 89 is 3 with a remainder of 26.
The number 3 becomes the next digit in our result. 
Result so far: 453.0
Subtracting 267 from 293 leaves us with 26.
Take the next digit (9) from the dividend and append it to 26, then repeat: 269 / 89

Let's proceed to step 6:
269 divided by 89 is 3 with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 4533.0
Deduct 267 from 269 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
The number 89 fits into 20 0 times, leaving a remainder of 20.
The next digit of our result is 0. 
Result so far: 4533.0
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 8:
89 can be fit into 200 2 times, resulting in a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 4533.02
Deduct 178 from 200 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Let's proceed to step 9:
89 can be fit into 220 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 4533.022
The remainder is 42 after subtracting 178 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

The final result is 4533.022 with a remainder of 0.0042.
