250909 ÷ 89 
The aim is to understand the frequency of 89 in 250909.

Step 1:
89 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 89

Going ahead to step 2:
89 goes into 25 0 times with a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Grab the next digit (0) from the dividend, add it to 25, then carry on: 250 / 89

Going ahead to step 3:
When dividing 250 by 89, we get 2 with a remainder of 72.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 178 away from 250, we end up with 72.
Take the next digit (9) from the dividend and append it to 72, then repeat: 729 / 89

Going ahead to step 4:
If we divide 729 by 89, we get 8 and a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Subtract 712 from 729 to get 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 89

Going ahead to step 5:
When dividing 170 by 89, we get 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 281.0
Subtract 89 from 170 to get 81.
Bring next digit (9) of the dividend behind the 81 and repeat the process: 819 / 89

On to step 6:
819 divided by 89 is 9 with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 2819.0
The remainder is 18 after subtracting 801 from 819.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
89 goes into 180 2 times with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 2819.2
Subtracting 178 from 180 leaves us 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.

On to step 8:
20 divided by 89 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 2819.2
Subtracting 0 from 20 leaves us 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.

Advancing to step 9:
89 goes into 200 2 times with a remainder of 22.
Put 2 as the next digit of the answer. 
Result so far: 2819.202
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.

Step 10:
89 can be fit into 220 2 times, resulting in a remainder of 42.
The next digit of our result is 2. 
Result so far: 2819.2022
The remainder is 42 after subtracting 178 from 220.
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 2819.2022 with a remainder of 0.00042.
