We look at the division of 813002 by 89 
The aim is to understand the frequency of 89 in 813002.

Moving on to step 1:
89 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 89

Let's proceed to step 2:
If we divide 81 by 89, we get 0 and a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 89

Let's proceed to step 3:
If we divide 813 by 89, we get 9 and a remainder of 12.
Use 9 as the next digit of our solution. 
Result so far: 9.0
The remainder is 12 after subtracting 801 from 813.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 89

Let's proceed to step 4:
89 goes into 120 1 times with a remainder of 31.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we subtract 89 from 120, we get 31.
Grab the next digit (0) from the dividend, add it to 31, then carry on: 310 / 89

On to step 5:
89 can be fit into 310 3 times, resulting in a remainder of 43.
Put 3 as the next digit of the answer. 
Result so far: 913.0
Subtracting 267 from 310 leaves us with 43.
Fetch the next digit (2) from the dividend, attach it to 43 and continue: 432 / 89

Let's proceed to step 6:
The number 89 fits into 432 4 times, leaving a remainder of 76.
The next digit of our result is 4. 
Result so far: 9134.0
Deduct 356 from 432 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 7:
The number 89 fits into 760 8 times, leaving a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 9134.8
The remainder is 48 after subtracting 712 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 8:
If we divide 480 by 89, we get 5 and a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 9134.85
Deduct 445 from 480 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 9:
89 goes into 350 3 times with a remainder of 83.
Write down 3 as next digit of the result. 
Result so far: 9134.853
If we subtract 267 from 350, we get 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 10:
830 divided by 89 is 9 with a remainder of 29.
Use 9 as the next digit of our solution. 
Result so far: 9134.8539
If we take 801 away from 830, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 11:
89 goes into 290 3 times with a remainder of 23.
Use 3 as the next digit of our solution. 
Result so far: 9134.85393
If we take 267 away from 290, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 12:
The number 89 fits into 230 2 times, leaving a remainder of 52.
The next digit of our result is 2. 
Result so far: 9134.853932
If we subtract 178 from 230, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 13:
89 can be fit into 520 5 times, resulting in a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 9134.8539325
If we take 445 away from 520, we end up with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Moving on to step 14:
When dividing 750 by 89, we get 8 with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 9134.85393258
If we subtract 712 from 750, we get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The final outcome is 9134.85393258, with a leftover of 3.8e-08.
