772346 ÷ 45 
The aim is to understand the frequency of 45 in 772346.

Advancing to step 1:
45 goes into 7 0 times with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 45

Step 2:
When dividing 77 by 45, we get 1 with a remainder of 32.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 77 to get 32.
Include the next digit (2) from the dividend after 32, then repeat: 322 / 45

Going ahead to step 3:
45 goes into 322 7 times with a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 17.0
The remainder is 7 after subtracting 315 from 322.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 45

Step 4:
45 goes into 73 1 times with a remainder of 28.
The next digit of our result is 1. 
Result so far: 171.0
The remainder is 28 after subtracting 45 from 73.
Append the next digit (4) from the dividend to 28 and continue with: 284 / 45

Going ahead to step 5:
When dividing 284 by 45, we get 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 1716.0
Subtracting 270 from 284 leaves us with 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 45

Step 6:
45 can be fit into 146 3 times, resulting in a remainder of 11.
Put 3 as the next digit of the answer. 
Result so far: 17163.0
Deduct 135 from 146 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 7:
When dividing 110 by 45, we get 2 with a remainder of 20.
Write down 2 as next digit of the result. 
Result so far: 17163.2
Subtracting 90 from 110 leaves us 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.

Advancing to step 8:
When dividing 200 by 45, we get 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17163.24
Subtract 180 from 200 to get 20.
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 9:
200 divided by 45 is 4 with a remainder of 20.
Put 4 as the next digit of the answer. 
Result so far: 17163.244
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 17163.244 and a remainder of 0.002.
