597270 ÷ 45 
The aim is to understand the frequency of 45 in 597270.

Going ahead to step 1:
When dividing 5 by 45, we get 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Append the next digit (9) from the dividend to 5 and continue with: 59 / 45

On to step 2:
If we divide 59 by 45, we get 1 and a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 14 after subtracting 45 from 59.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 45

Going ahead to step 3:
147 divided by 45 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 13.0
Deduct 135 from 147 and we're left with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 45

Going ahead to step 4:
45 goes into 122 2 times with a remainder of 32.
Write down 2 as next digit of the result. 
Result so far: 132.0
Subtracting 90 from 122 leaves us with 32.
Take the next digit (7) from the dividend and append it to 32, then repeat: 327 / 45

Step 5:
45 can be fit into 327 7 times, resulting in a remainder of 12.
Put 7 as the next digit of the answer. 
Result so far: 1327.0
Subtract 315 from 327 to get 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 45

On to step 6:
When dividing 120 by 45, we get 2 with a remainder of 30.
The next digit of our result is 2. 
Result so far: 13272.0
Subtract 90 from 120 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 7:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 13272.6
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 13272.66
If we subtract 270 from 300, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final outcome is 13272.66, with a leftover of 0.03.
