We look at the division of 772294 by 45 
The aim is to understand the frequency of 45 in 772294.

On to step 1:
7 divided by 45 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (7) from the dividend and append it to 7, then repeat: 77 / 45

Moving on to step 2:
45 can be fit into 77 1 times, resulting in a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 45 away from 77, we end up with 32.
Bring next digit (2) of the dividend behind the 32 and repeat the process: 322 / 45

Moving on to step 3:
If we divide 322 by 45, we get 7 and 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.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 45

Going ahead to step 4:
The number 45 fits into 72 1 times, leaving a remainder of 27.
The next digit of our result is 1. 
Result so far: 171.0
If we subtract 45 from 72, we get 27.
Append the next digit (9) from the dividend to 27 and continue with: 279 / 45

On to step 5:
The number 45 fits into 279 6 times, leaving a remainder of 9.
Use 6 as the next digit of our solution. 
Result so far: 1716.0
The remainder is 9 after subtracting 270 from 279.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 45

Moving on to step 6:
If we divide 94 by 45, we get 2 and a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 17162.0
Subtracting 90 from 94 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
40 divided by 45 is 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 17162.0
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 8:
When dividing 400 by 45, we get 8 with a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 17162.08
Subtracting 360 from 400 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 9:
When dividing 400 by 45, we get 8 with a remainder of 40.
The next digit of our result is 8. 
Result so far: 17162.088
If we take 360 away from 400, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The quotient of the division is 17162.088, and the remainder is 0.004.
