We look at the division of 178673 by 45 
The aim is to understand the frequency of 45 in 178673.

Moving on to step 1:
45 can be fit into 1 0 times, resulting in a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 45

Going ahead to step 2:
17 divided by 45 is 0 with a remainder of 17.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 17 after subtracting 0 from 17.
Take the next digit (8) from the dividend and append it to 17, then repeat: 178 / 45

Moving on to step 3:
When dividing 178 by 45, we get 3 with a remainder of 43.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 43 after subtracting 135 from 178.
Append the next digit (6) from the dividend to 43 and continue with: 436 / 45

On to step 4:
If we divide 436 by 45, we get 9 and a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 39.0
The remainder is 31 after subtracting 405 from 436.
Grab the next digit (7) from the dividend, add it to 31, then carry on: 317 / 45

On to step 5:
45 can be fit into 317 7 times, resulting in a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 397.0
Subtract 315 from 317 to get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 45

Let's proceed to step 6:
When dividing 23 by 45, we get 0 with a remainder of 23.
Put 0 as the next digit of the answer. 
Result so far: 3970.0
If we subtract 0 from 23, we get 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 7:
45 can be fit into 230 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 3970.5
Subtract 225 from 230 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
50 divided by 45 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3970.51
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
If we divide 50 by 45, we get 1 and a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 3970.511
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 3970.511 with a balance of 0.0005.
