We look at the division of 404816 by 89 
The aim is to understand the frequency of 89 in 404816.

Advancing to step 1:
4 divided by 89 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (0) from the dividend, attach it to 4 and continue: 40 / 89

Let's proceed to step 2:
40 divided by 89 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Take the next digit (4) from the dividend and append it to 40, then repeat: 404 / 89

Step 3:
89 can be fit into 404 4 times, resulting in a remainder of 48.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtract 356 from 404 to get 48.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 89

Step 4:
The number 89 fits into 488 5 times, leaving a remainder of 43.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Subtracting 445 from 488 leaves us with 43.
Include the next digit (1) from the dividend after 43, then repeat: 431 / 89

Moving on to step 5:
89 can be fit into 431 4 times, resulting in a remainder of 75.
The next digit of our result is 4. 
Result so far: 454.0
If we subtract 356 from 431, we get 75.
Fetch the next digit (6) from the dividend, attach it to 75 and continue: 756 / 89

Step 6:
89 goes into 756 8 times with a remainder of 44.
Put 8 as the next digit of the answer. 
Result so far: 4548.0
If we take 712 away from 756, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 7:
89 goes into 440 4 times with a remainder of 84.
Record the quotient 4 as the next digit in the result. 
Result so far: 4548.4
Deduct 356 from 440 and we're left with 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Advancing to step 8:
The number 89 fits into 840 9 times, leaving a remainder of 39.
The next digit of our result is 9. 
Result so far: 4548.49
Subtracting 801 from 840 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
If we divide 390 by 89, we get 4 and a remainder of 34.
Use 4 as the next digit of our solution. 
Result so far: 4548.494
Subtracting 356 from 390 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 10:
If we divide 340 by 89, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 4548.4943
If we subtract 267 from 340, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
89 can be fit into 730 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 4548.49438
Subtracting 712 from 730 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 89 fits into 180 2 times, leaving a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 4548.494382
Deduct 178 from 180 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.

Step 13:
20 divided by 89 is 0 with a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 4548.494382
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.

Moving on to step 14:
If we divide 200 by 89, we get 2 and a remainder of 22.
Write down 2 as next digit of the result. 
Result so far: 4548.49438202
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.

The final outcome is 4548.49438202, with a leftover of 2.2e-08.
