42751 ÷ 45 
The aim is to understand the frequency of 45 in 42751.

Moving on 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.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 45

Step 2:
42 divided by 45 is 0 with a remainder of 42.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Fetch the next digit (7) from the dividend, attach it to 42 and continue: 427 / 45

Going ahead to step 3:
When dividing 427 by 45, we get 9 with a remainder of 22.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Deduct 405 from 427 and we're left with 22.
Take the next digit (5) from the dividend and append it to 22, then repeat: 225 / 45

Advancing to step 4:
When dividing 225 by 45, we get 5 with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 95.0
Subtract 225 from 225 to get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 45

Going ahead to step 5:
45 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 950.0
Subtracting 0 from 1 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 6:
If we divide 10 by 45, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 950.0
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 7:
45 can be fit into 100 2 times, resulting in a remainder of 10.
The next digit of our result is 2. 
Result so far: 950.02
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 45, we get 2 and a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 950.022
Subtracting 90 from 100 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

In conclusion, the division gives 950.022 with a balance of 0.001.
