We look at the division of 215183 by 89 
The aim is to understand the frequency of 89 in 215183.

On to step 1:
89 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 89

Step 2:
If we divide 21 by 89, we get 0 and a remainder of 21.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Take the next digit (5) from the dividend and append it to 21, then repeat: 215 / 89

Step 3:
If we divide 215 by 89, we get 2 and a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we take 178 away from 215, we end up with 37.
Bring next digit (1) of the dividend behind the 37 and repeat the process: 371 / 89

On to step 4:
371 divided by 89 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 24.0
Subtract 356 from 371 to get 15.
Grab the next digit (8) from the dividend, add it to 15, then carry on: 158 / 89

Step 5:
158 divided by 89 is 1 with a remainder of 69.
The next digit of our result is 1. 
Result so far: 241.0
The remainder is 69 after subtracting 89 from 158.
Fetch the next digit (3) from the dividend, attach it to 69 and continue: 693 / 89

Let's proceed to step 6:
89 goes into 693 7 times with a remainder of 70.
Write down 7 as next digit of the result. 
Result so far: 2417.0
If we subtract 623 from 693, we get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Moving on to step 7:
700 divided by 89 is 7 with a remainder of 77.
The number 7 becomes the next digit in our result. 
Result so far: 2417.7
Subtract 623 from 700 to get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Moving on to step 8:
89 goes into 770 8 times with a remainder of 58.
The number 8 becomes the next digit in our result. 
Result so far: 2417.78
The remainder is 58 after subtracting 712 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Going ahead to step 9:
580 divided by 89 is 6 with a remainder of 46.
Put 6 as the next digit of the answer. 
Result so far: 2417.786
If we subtract 534 from 580, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Let's proceed to step 10:
If we divide 460 by 89, we get 5 and a remainder of 15.
The next digit of our result is 5. 
Result so far: 2417.7865
Subtracting 445 from 460 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 11:
The number 89 fits into 150 1 times, leaving a remainder of 61.
Use 1 as the next digit of our solution. 
Result so far: 2417.78651
Subtracting 89 from 150 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
The number 89 fits into 610 6 times, leaving a remainder of 76.
The number 6 becomes the next digit in our result. 
Result so far: 2417.786516
If we subtract 534 from 610, we get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 13:
760 divided by 89 is 8 with a remainder of 48.
Use 8 as the next digit of our solution. 
Result so far: 2417.7865168
If we subtract 712 from 760, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
If we divide 480 by 89, we get 5 and a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 2417.78651685
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.

Our division results in 2417.78651685 with a remaining 3.5e-08.
