494161 divided by 45 
The aim is to understand the frequency of 45 in 494161.

Let's proceed to step 1:
45 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 45

Moving on to step 2:
45 can be fit into 49 1 times, resulting in a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 45 from 49 leaves us with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 45

Advancing to step 3:
45 can be fit into 44 0 times, resulting in a remainder of 44.
Put 0 as the next digit of the answer. 
Result so far: 10.0
Subtract 0 from 44 to get 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 45

Going ahead to step 4:
441 divided by 45 is 9 with a remainder of 36.
Put 9 as the next digit of the answer. 
Result so far: 109.0
Deduct 405 from 441 and we're left with 36.
Include the next digit (6) from the dividend after 36, then repeat: 366 / 45

Advancing to step 5:
If we divide 366 by 45, we get 8 and a remainder of 6.
Use 8 as the next digit of our solution. 
Result so far: 1098.0
Deduct 360 from 366 and we're left with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 45

On to step 6:
When dividing 61 by 45, we get 1 with a remainder of 16.
Record the quotient 1 as the next digit in the result. 
Result so far: 10981.0
Deduct 45 from 61 and we're left with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
160 divided by 45 is 3 with a remainder of 25.
The next digit of our result is 3. 
Result so far: 10981.3
The remainder is 25 after subtracting 135 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Let's proceed to step 8:
The number 45 fits into 250 5 times, leaving a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 10981.35
The remainder is 25 after subtracting 225 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Step 9:
45 can be fit into 250 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 10981.355
If we take 225 away from 250, we end up with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

After the division, we end up with 10981.355 and a remainder of 0.0025.
