396525 ÷ 89 
The aim is to understand the frequency of 89 in 396525.

Going ahead to step 1:
89 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 89

Moving on to step 2:
When dividing 39 by 89, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 39, we end up with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 89

Going ahead to step 3:
The number 89 fits into 396 4 times, leaving a remainder of 40.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Deduct 356 from 396 and we're left with 40.
Bring next digit (5) of the dividend behind the 40 and repeat the process: 405 / 89

Going ahead to step 4:
The number 89 fits into 405 4 times, leaving a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtract 356 from 405 to get 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 89

Going ahead to step 5:
89 goes into 492 5 times with a remainder of 47.
The next digit of our result is 5. 
Result so far: 445.0
Subtracting 445 from 492 leaves us with 47.
Fetch the next digit (5) from the dividend, attach it to 47 and continue: 475 / 89

On to step 6:
When dividing 475 by 89, we get 5 with a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 4455.0
If we take 445 away from 475, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
If we divide 300 by 89, we get 3 and a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 4455.3
If we take 267 away from 300, 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.

Going ahead to step 8:
The number 89 fits into 330 3 times, leaving a remainder of 63.
Put 3 as the next digit of the answer. 
Result so far: 4455.33
If we take 267 away from 330, we end up with 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 630, and continue the process.

The final outcome is 4455.33, with a leftover of 0.063.
