We're dividing 169823 by 89 
The aim is to understand the frequency of 89 in 169823.

Going ahead to step 1:
When dividing 1 by 89, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 89

Let's proceed to step 2:
89 goes into 16 0 times with a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 16, we end up with 16.
Take the next digit (9) from the dividend and append it to 16, then repeat: 169 / 89

Advancing to step 3:
If we divide 169 by 89, we get 1 and a remainder of 80.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 89 away from 169, we end up with 80.
Grab the next digit (8) from the dividend, add it to 80, then carry on: 808 / 89

Moving on to step 4:
When dividing 808 by 89, we get 9 with a remainder of 7.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 801 from 808 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 89

On to step 5:
89 goes into 72 0 times with a remainder of 72.
The number 0 becomes the next digit in our result. 
Result so far: 190.0
Deduct 0 from 72 and we're left with 72.
Append the next digit (3) from the dividend to 72 and continue with: 723 / 89

Let's proceed to step 6:
89 can be fit into 723 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 1908.0
If we take 712 away from 723, we end up with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 7:
The number 89 fits into 110 1 times, leaving a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 1908.1
If we take 89 away from 110, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Advancing to step 8:
When dividing 210 by 89, we get 2 with a remainder of 32.
The number 2 becomes the next digit in our result. 
Result so far: 1908.12
If we subtract 178 from 210, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Step 9:
If we divide 320 by 89, we get 3 and a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 1908.123
Deduct 267 from 320 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 10:
The number 89 fits into 530 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 1908.1235
Deduct 445 from 530 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 11:
When dividing 850 by 89, we get 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 1908.12359
Subtracting 801 from 850 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 12:
490 divided by 89 is 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 1908.123595
Subtracting 445 from 490 leaves us with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Step 13:
If we divide 450 by 89, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 1908.1235955
Subtracting 445 from 450 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 1908.1235955 with a remainder of 5e-08.
