We're dividing 27915 by 45 
The aim is to understand the frequency of 45 in 27915.

Moving on to step 1:
2 divided by 45 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 45

Let's proceed to step 2:
When dividing 27 by 45, we get 0 with a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 27, we end up with 27.
Bring next digit (9) of the dividend behind the 27 and repeat the process: 279 / 45

Moving on to step 3:
If we divide 279 by 45, we get 6 and a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 270 from 279, we get 9.
Take the next digit (1) from the dividend and append it to 9, then repeat: 91 / 45

On to step 4:
45 can be fit into 91 2 times, resulting in a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 62.0
Deduct 90 from 91 and we're left with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 45

On to step 5:
If we divide 15 by 45, we get 0 and a remainder of 15.
Write down 0 as next digit of the result. 
Result so far: 620.0
If we take 0 away from 15, we end up 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.

On to step 6:
If we divide 150 by 45, we get 3 and a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 620.3
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 7:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Record the quotient 3 as the next digit in the result. 
Result so far: 620.33
Deduct 135 from 150 and we're left 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.

Our division results in 620.33 with a remaining 0.015.
