We're dividing 537225 by 57 
The aim is to understand the frequency of 57 in 537225.

On to step 1:
If we divide 5 by 57, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 57

Advancing to step 2:
If we divide 53 by 57, we get 0 and a remainder of 53.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (7) from the dividend and append it to 53, then repeat: 537 / 57

Step 3:
537 divided by 57 is 9 with a remainder of 24.
Write down 9 as next digit of the result. 
Result so far: 9.0
Subtracting 513 from 537 leaves us with 24.
Fetch the next digit (2) from the dividend, attach it to 24 and continue: 242 / 57

Moving on to step 4:
57 can be fit into 242 4 times, resulting in a remainder of 14.
Record the quotient 4 as the next digit in the result. 
Result so far: 94.0
If we take 228 away from 242, we end up with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 57

Advancing to step 5:
142 divided by 57 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 942.0
If we take 114 away from 142, we end up with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 57

Going ahead to step 6:
The number 57 fits into 285 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 9425.0
Subtracting 285 from 285 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
When dividing 0 by 57, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9425.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
The number 57 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 9425.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 9425.0, and the remainder is 0.0.
