752074 ÷ 45 
The aim is to understand the frequency of 45 in 752074.

Moving on to step 1:
45 goes into 7 0 times with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Append the next digit (5) from the dividend to 7 and continue with: 75 / 45

Advancing to step 2:
75 divided by 45 is 1 with a remainder of 30.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 45 from 75 to get 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 45

Moving on to step 3:
45 can be fit into 302 6 times, resulting in a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 16.0
Subtract 270 from 302 to get 32.
Include the next digit (0) from the dividend after 32, then repeat: 320 / 45

Going ahead to step 4:
45 can be fit into 320 7 times, resulting in a remainder of 5.
The next digit of our result is 7. 
Result so far: 167.0
If we take 315 away from 320, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 45

Advancing to step 5:
45 can be fit into 57 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1671.0
If we take 45 away from 57, we end up with 12.
Bring next digit (4) of the dividend behind the 12 and repeat the process: 124 / 45

Let's proceed to step 6:
124 divided by 45 is 2 with a remainder of 34.
The number 2 becomes the next digit in our result. 
Result so far: 16712.0
The remainder is 34 after subtracting 90 from 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 7:
45 goes into 340 7 times with a remainder of 25.
The next digit of our result is 7. 
Result so far: 16712.7
Deduct 315 from 340 and we're left 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.

Let's proceed to step 8:
If we divide 250 by 45, we get 5 and a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16712.75
Subtract 225 from 250 to get 25.
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 9:
250 divided by 45 is 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 16712.755
Subtract 225 from 250 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

In conclusion, the division gives 16712.755 with a balance of 0.0025.
