We look at the division of 738205 by 45 
The aim is to understand the frequency of 45 in 738205.

Going ahead to step 1:
If we divide 7 by 45, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 45

Going ahead to step 2:
If we divide 73 by 45, we get 1 and a remainder of 28.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 28 after subtracting 45 from 73.
Take the next digit (8) from the dividend and append it to 28, then repeat: 288 / 45

Moving on to step 3:
The number 45 fits into 288 6 times, leaving a remainder of 18.
Put 6 as the next digit of the answer. 
Result so far: 16.0
If we take 270 away from 288, we end up with 18.
Bring next digit (2) of the dividend behind the 18 and repeat the process: 182 / 45

Let's proceed to step 4:
182 divided by 45 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 164.0
Subtracting 180 from 182 leaves us with 2.
Take the next digit (0) from the dividend and append it to 2, then repeat: 20 / 45

Going ahead to step 5:
When dividing 20 by 45, we get 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 1640.0
The remainder is 20 after subtracting 0 from 20.
Grab the next digit (5) from the dividend, add it to 20, then carry on: 205 / 45

Let's proceed to step 6:
If we divide 205 by 45, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 16404.0
Subtract 180 from 205 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 7:
When dividing 250 by 45, we get 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 16404.5
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.

Advancing to step 8:
When dividing 250 by 45, we get 5 with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 16404.55
Subtracting 225 from 250 leaves us 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.

Our division results in 16404.55 with a remaining 0.025.
