We divide 300372 by 89
The aim is to understand the frequency of 89 in 300372.

Let's proceed to step 1:
3 divided by 89 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 89

Moving on to step 2:
The number 89 fits into 30 0 times, leaving a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 30, we get 30.
Take the next digit (0) from the dividend and append it to 30, then repeat: 300 / 89

Advancing to step 3:
The number 89 fits into 300 3 times, leaving a remainder of 33.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 267 from 300 leaves us with 33.
Append the next digit (3) from the dividend to 33 and continue with: 333 / 89

Going ahead to step 4:
89 can be fit into 333 3 times, resulting in a remainder of 66.
The next digit of our result is 3. 
Result so far: 33.0
If we take 267 away from 333, we end up with 66.
Include the next digit (7) from the dividend after 66, then repeat: 667 / 89

On to step 5:
667 divided by 89 is 7 with a remainder of 44.
Use 7 as the next digit of our solution. 
Result so far: 337.0
Deduct 623 from 667 and we're left with 44.
Fetch the next digit (2) from the dividend, attach it to 44 and continue: 442 / 89

Advancing to step 6:
89 can be fit into 442 4 times, resulting in a remainder of 86.
Use 4 as the next digit of our solution. 
Result so far: 3374.0
If we subtract 356 from 442, we get 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

Advancing to step 7:
89 goes into 860 9 times with a remainder of 59.
Record the quotient 9 as the next digit in the result. 
Result so far: 3374.9
If we subtract 801 from 860, we get 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Advancing to step 8:
If we divide 590 by 89, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 3374.96
Subtract 534 from 590 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 9:
If we divide 560 by 89, we get 6 and a remainder of 26.
Write down 6 as next digit of the result. 
Result so far: 3374.966
If we take 534 away from 560, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final outcome is 3374.966, with a leftover of 0.0026.
