515045 ÷ 89 
The aim is to understand the frequency of 89 in 515045.

Advancing to step 1:
89 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 89

On to step 2:
When dividing 51 by 89, we get 0 with a remainder of 51.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 51 and we're left with 51.
Bring next digit (5) of the dividend behind the 51 and repeat the process: 515 / 89

Let's proceed to step 3:
The number 89 fits into 515 5 times, leaving a remainder of 70.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 445 from 515 leaves us with 70.
Bring next digit (0) of the dividend behind the 70 and repeat the process: 700 / 89

On to step 4:
89 goes into 700 7 times with a remainder of 77.
Put 7 as the next digit of the answer. 
Result so far: 57.0
Subtracting 623 from 700 leaves us with 77.
Bring next digit (4) of the dividend behind the 77 and repeat the process: 774 / 89

Moving on to step 5:
89 can be fit into 774 8 times, resulting in a remainder of 62.
The next digit of our result is 8. 
Result so far: 578.0
Subtracting 712 from 774 leaves us with 62.
Include the next digit (5) from the dividend after 62, then repeat: 625 / 89

On to step 6:
If we divide 625 by 89, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 5787.0
Deduct 623 from 625 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 number 0 becomes the next digit in our result. 
Result so far: 5787.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 8:
89 goes into 200 2 times with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 5787.02
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.

Moving on to step 9:
89 goes into 220 2 times with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 5787.022
If we subtract 178 from 220, 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.

The final result is 5787.022 with a remainder of 0.0042.
