45920 divided by 89 
The aim is to understand the frequency of 89 in 45920.

Let's proceed to step 1:
When dividing 4 by 89, we get 0 with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (5) from the dividend after 4, then repeat: 45 / 89

Let's proceed to step 2:
89 can be fit into 45 0 times, resulting in a remainder of 45.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 45 after subtracting 0 from 45.
Include the next digit (9) from the dividend after 45, then repeat: 459 / 89

Let's proceed to step 3:
When dividing 459 by 89, we get 5 with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 445 away from 459, we end up with 14.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 89

Step 4:
89 goes into 142 1 times with a remainder of 53.
The number 1 becomes the next digit in our result. 
Result so far: 51.0
Subtract 89 from 142 to get 53.
Grab the next digit (0) from the dividend, add it to 53, then carry on: 530 / 89

On to step 5:
The number 89 fits into 530 5 times, leaving a remainder of 85.
Record the quotient 5 as the next digit in the result. 
Result so far: 515.0
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.

Step 6:
When dividing 850 by 89, we get 9 with a remainder of 49.
Write down 9 as next digit of the result. 
Result so far: 515.9
If we subtract 801 from 850, we get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Moving on to step 7:
If we divide 490 by 89, we get 5 and a remainder of 45.
The next digit of our result is 5. 
Result so far: 515.95
The remainder is 45 after subtracting 445 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
89 can be fit into 450 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 515.955
The remainder is 5 after subtracting 445 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 515.955 and a remainder of 0.0005.
