We're dividing 273089 by 45 
The aim is to understand the frequency of 45 in 273089.

On to step 1:
When dividing 2 by 45, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 45

Moving on to step 2:
The number 45 fits into 27 0 times, leaving a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 27 after subtracting 0 from 27.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 45

Let's proceed to step 3:
273 divided by 45 is 6 with a remainder of 3.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 270 away from 273, we end up with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 45

Going ahead to step 4:
When dividing 30 by 45, we get 0 with a remainder of 30.
The next digit of our result is 0. 
Result so far: 60.0
Subtracting 0 from 30 leaves us with 30.
Include the next digit (8) from the dividend after 30, then repeat: 308 / 45

Step 5:
308 divided by 45 is 6 with a remainder of 38.
Put 6 as the next digit of the answer. 
Result so far: 606.0
The remainder is 38 after subtracting 270 from 308.
Include the next digit (9) from the dividend after 38, then repeat: 389 / 45

Advancing to step 6:
If we divide 389 by 45, we get 8 and a remainder of 29.
The number 8 becomes the next digit in our result. 
Result so far: 6068.0
Subtract 360 from 389 to get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Moving on to step 7:
If we divide 290 by 45, we get 6 and a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 6068.6
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
Write down 4 as next digit of the result. 
Result so far: 6068.64
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
45 goes into 200 4 times with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 6068.644
The remainder is 20 after subtracting 180 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 6068.644 with a remainder of 0.002.
