We look at the division of 125533 by 57 
The aim is to understand the frequency of 57 in 125533.

Let's proceed to step 1:
When dividing 1 by 57, we get 0 with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 57

On to step 2:
12 divided by 57 is 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Grab the next digit (5) from the dividend, add it to 12, then carry on: 125 / 57

Step 3:
57 goes into 125 2 times with a remainder of 11.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 114 from 125 and we're left with 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 57

Let's proceed to step 4:
57 goes into 115 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 114 away from 115, we end up with 1.
Bring next digit (3) of the dividend behind the 1 and repeat the process: 13 / 57

Let's proceed to step 5:
The number 57 fits into 13 0 times, leaving a remainder of 13.
Record the quotient 0 as the next digit in the result. 
Result so far: 220.0
Subtracting 0 from 13 leaves us with 13.
Take the next digit (3) from the dividend and append it to 13, then repeat: 133 / 57

On to step 6:
If we divide 133 by 57, we get 2 and a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2202.0
If we take 114 away from 133, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Let's proceed to step 7:
190 divided by 57 is 3 with a remainder of 19.
The next digit of our result is 3. 
Result so far: 2202.3
Subtract 171 from 190 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 8:
If we divide 190 by 57, we get 3 and a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 2202.33
Deduct 171 from 190 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

After the division, we end up with 2202.33 and a remainder of 0.019.
