We look at the division of 55007755 by 57 
The aim is to understand the frequency of 57 in 55007755.

Let's proceed to step 1:
When dividing 5 by 57, we get 0 with 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.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 57

Step 2:
57 goes into 55 0 times with a remainder of 55.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 55 after subtracting 0 from 55.
Take the next digit (0) from the dividend and append it to 55, then repeat: 550 / 57

Step 3:
57 can be fit into 550 9 times, resulting in a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 513 away from 550, we end up with 37.
Append the next digit (0) from the dividend to 37 and continue with: 370 / 57

Moving on to step 4:
57 goes into 370 6 times with a remainder of 28.
The next digit of our result is 6. 
Result so far: 96.0
The remainder is 28 after subtracting 342 from 370.
Include the next digit (7) from the dividend after 28, then repeat: 287 / 57

Moving on to step 5:
57 goes into 287 5 times with a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 965.0
Subtract 285 from 287 to get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 57

Going ahead to step 6:
57 goes into 27 0 times with a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 9650.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (5) from the dividend after 27, then repeat: 275 / 57

Advancing to step 7:
275 divided by 57 is 4 with a remainder of 47.
The number 4 becomes the next digit in our result. 
Result so far: 96504.0
Deduct 228 from 275 and we're left with 47.
Include the next digit (5) from the dividend after 47, then repeat: 475 / 57

Advancing to step 8:
If we divide 475 by 57, we get 8 and a remainder of 19.
Put 8 as the next digit of the answer. 
Result so far: 965048.0
Subtracting 456 from 475 leaves us 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.

Moving on to step 9:
190 divided by 57 is 3 with a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 965048.3
If we take 171 away from 190, 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.

Going ahead to step 10:
57 goes into 190 3 times with a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 965048.33
If we take 171 away from 190, 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.

After the division, we end up with 965048.33 and a remainder of 0.019.
