Let's divide 188993 by 45
The aim is to understand the frequency of 45 in 188993.

Moving 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
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 45

On to step 2:
If we divide 18 by 45, we get 0 and a remainder of 18.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 18 and we're left with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 45

Going ahead to step 3:
If we divide 188 by 45, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 180 from 188, we get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 45

Let's proceed to step 4:
If we divide 89 by 45, we get 1 and a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 41.0
If we subtract 45 from 89, we get 44.
Bring next digit (9) of the dividend behind the 44 and repeat the process: 449 / 45

On to step 5:
The number 45 fits into 449 9 times, leaving a remainder of 44.
Record the quotient 9 as the next digit in the result. 
Result so far: 419.0
If we take 405 away from 449, we end up with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 45

Moving on to step 6:
45 can be fit into 443 9 times, resulting in a remainder of 38.
The number 9 becomes the next digit in our result. 
Result so far: 4199.0
If we take 405 away from 443, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 7:
45 goes into 380 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 4199.8
The remainder is 20 after subtracting 360 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 8:
200 divided by 45 is 4 with a remainder of 20.
The next digit of our result is 4. 
Result so far: 4199.84
Deduct 180 from 200 and we're left 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.

Moving on to step 9:
45 goes into 200 4 times with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 4199.844
Deduct 180 from 200 and we're left 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.

The quotient of the division is 4199.844, and the remainder is 0.002.
