We're dividing 809813 by 89 
The aim is to understand the frequency of 89 in 809813.

Going ahead to step 1:
8 divided by 89 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 89

Going ahead to step 2:
89 goes into 80 0 times with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 80, we end up with 80.
Fetch the next digit (9) from the dividend, attach it to 80 and continue: 809 / 89

Going ahead to step 3:
When dividing 809 by 89, we get 9 with a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 8 after subtracting 801 from 809.
Fetch the next digit (8) from the dividend, attach it to 8 and continue: 88 / 89

Let's proceed to step 4:
The number 89 fits into 88 0 times, leaving a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 90.0
If we take 0 away from 88, we end up with 88.
Fetch the next digit (1) from the dividend, attach it to 88 and continue: 881 / 89

Step 5:
The number 89 fits into 881 9 times, leaving a remainder of 80.
Record the quotient 9 as the next digit in the result. 
Result so far: 909.0
If we take 801 away from 881, we end up with 80.
Include the next digit (3) from the dividend after 80, then repeat: 803 / 89

Step 6:
If we divide 803 by 89, we get 9 and a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 9099.0
The remainder is 2 after subtracting 801 from 803.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
89 goes into 20 0 times with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 9099.0
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.

Going ahead to step 8:
When dividing 200 by 89, we get 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 9099.02
Subtract 178 from 200 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 9:
220 divided by 89 is 2 with a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 9099.022
If we take 178 away from 220, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Our division results in 9099.022 with a remaining 0.0042.
