We divide 571700 by 45
The aim is to understand the frequency of 45 in 571700.

Advancing to step 1:
45 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 45

On to step 2:
If we divide 57 by 45, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 45 from 57, we get 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 45

Advancing to step 3:
121 divided by 45 is 2 with a remainder of 31.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 90 from 121 to get 31.
Take the next digit (7) from the dividend and append it to 31, then repeat: 317 / 45

Advancing to step 4:
317 divided by 45 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we take 315 away from 317, we end up with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 45

Step 5:
The number 45 fits into 20 0 times, leaving a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 1270.0
Deduct 0 from 20 and we're left with 20.
Take the next digit (0) from the dividend and append it to 20, then repeat: 200 / 45

Let's proceed to step 6:
45 can be fit into 200 4 times, resulting in a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 12704.0
Deduct 180 from 200 and we're left 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.

Step 7:
200 divided by 45 is 4 with a remainder of 20.
Record the quotient 4 as the next digit in the result. 
Result so far: 12704.4
Subtracting 180 from 200 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.

Let's proceed to step 8:
If we divide 200 by 45, we get 4 and a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 12704.44
Subtracting 180 from 200 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.

Our division results in 12704.44 with a remaining 0.02.
