We look at the division of 235526 by 89 
The aim is to understand the frequency of 89 in 235526.

Step 1:
If we divide 2 by 89, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 89

Moving on to step 2:
The number 89 fits into 23 0 times, leaving a remainder of 23.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 23 to get 23.
Append the next digit (5) from the dividend to 23 and continue with: 235 / 89

Step 3:
When dividing 235 by 89, we get 2 with a remainder of 57.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 178 away from 235, we end up with 57.
Include the next digit (5) from the dividend after 57, then repeat: 575 / 89

Step 4:
575 divided by 89 is 6 with a remainder of 41.
Put 6 as the next digit of the answer. 
Result so far: 26.0
Deduct 534 from 575 and we're left with 41.
Append the next digit (2) from the dividend to 41 and continue with: 412 / 89

Step 5:
If we divide 412 by 89, we get 4 and a remainder of 56.
Use 4 as the next digit of our solution. 
Result so far: 264.0
Subtracting 356 from 412 leaves us with 56.
Append the next digit (6) from the dividend to 56 and continue with: 566 / 89

Going ahead to step 6:
The number 89 fits into 566 6 times, leaving a remainder of 32.
Use 6 as the next digit of our solution. 
Result so far: 2646.0
If we take 534 away from 566, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 7:
320 divided by 89 is 3 with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 2646.3
Subtracting 267 from 320 leaves us 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.

Advancing to step 8:
If we divide 530 by 89, we get 5 and a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 2646.35
The remainder is 85 after subtracting 445 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Let's proceed to step 9:
850 divided by 89 is 9 with a remainder of 49.
Record the quotient 9 as the next digit in the result. 
Result so far: 2646.359
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.

Step 10:
When dividing 490 by 89, we get 5 with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 2646.3595
Subtract 445 from 490 to get 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 11:
When dividing 450 by 89, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 2646.35955
If we take 445 away from 450, we end up 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.

Our division results in 2646.35955 with a remaining 5e-06.
