We're dividing 720553 by 89 
The aim is to understand the frequency of 89 in 720553.

Step 1:
89 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 89

On to step 2:
89 goes into 72 0 times with a remainder of 72.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 72, we end up with 72.
Include the next digit (0) from the dividend after 72, then repeat: 720 / 89

Step 3:
89 can be fit into 720 8 times, resulting in a remainder of 8.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtracting 712 from 720 leaves us with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 89

Going ahead to step 4:
89 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 85 leaves us with 85.
Take the next digit (5) from the dividend and append it to 85, then repeat: 855 / 89

Going ahead to step 5:
If we divide 855 by 89, we get 9 and a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 809.0
Subtract 801 from 855 to get 54.
Include the next digit (3) from the dividend after 54, then repeat: 543 / 89

Step 6:
543 divided by 89 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 8096.0
If we subtract 534 from 543, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
If we divide 90 by 89, we get 1 and a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 8096.1
The remainder is 1 after subtracting 89 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 8:
10 divided by 89 is 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 8096.1
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 9:
When dividing 100 by 89, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 8096.101
If we take 89 away from 100, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 10:
When dividing 110 by 89, we get 1 with a remainder of 21.
Record the quotient 1 as the next digit in the result. 
Result so far: 8096.1011
Subtract 89 from 110 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

The final outcome is 8096.1011, with a leftover of 0.00021.
