Let's divide 313854 by 45
The aim is to understand the frequency of 45 in 313854.

Advancing to step 1:
When dividing 3 by 45, we get 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 45

Going ahead to step 2:
45 goes into 31 0 times with a remainder of 31.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 31 to get 31.
Fetch the next digit (3) from the dividend, attach it to 31 and continue: 313 / 45

Step 3:
The number 45 fits into 313 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtract 270 from 313 to get 43.
Fetch the next digit (8) from the dividend, attach it to 43 and continue: 438 / 45

Moving on to step 4:
45 can be fit into 438 9 times, resulting in a remainder of 33.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we take 405 away from 438, we end up with 33.
Bring next digit (5) of the dividend behind the 33 and repeat the process: 335 / 45

Going ahead to step 5:
When dividing 335 by 45, we get 7 with a remainder of 20.
Put 7 as the next digit of the answer. 
Result so far: 697.0
If we subtract 315 from 335, we get 20.
Fetch the next digit (4) from the dividend, attach it to 20 and continue: 204 / 45

Let's proceed to step 6:
If we divide 204 by 45, we get 4 and a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 6974.0
Deduct 180 from 204 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 7:
45 can be fit into 240 5 times, resulting in a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 6974.5
Deduct 225 from 240 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.

On to step 8:
45 goes into 150 3 times with a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 6974.53
Subtracting 135 from 150 leaves us 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.

Let's proceed to step 9:
150 divided by 45 is 3 with a remainder of 15.
The next digit of our result is 3. 
Result so far: 6974.533
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.

In conclusion, the division gives 6974.533 with a balance of 0.0015.
