154449 divided by 45 
The aim is to understand the frequency of 45 in 154449.

On to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (5) of the dividend behind the 1 and repeat the process: 15 / 45

Moving on to step 2:
45 goes into 15 0 times with a remainder of 15.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Append the next digit (4) from the dividend to 15 and continue with: 154 / 45

Advancing to step 3:
If we divide 154 by 45, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 135 from 154, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 45

On to step 4:
If we divide 194 by 45, we get 4 and a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 34.0
Subtracting 180 from 194 leaves us with 14.
Bring next digit (4) of the dividend behind the 14 and repeat the process: 144 / 45

Step 5:
144 divided by 45 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 343.0
Subtracting 135 from 144 leaves us with 9.
Grab the next digit (9) from the dividend, add it to 9, then carry on: 99 / 45

Moving on to step 6:
99 divided by 45 is 2 with a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 3432.0
Subtract 90 from 99 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 7:
If we divide 90 by 45, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3432.2
If we subtract 90 from 90, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
When dividing 0 by 45, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3432.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
45 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3432.2
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 3432.2 with a remainder of 0.0.
