We look at the division of 61522 by 57 
The aim is to understand the frequency of 57 in 61522.

Advancing to step 1:
57 can be fit into 6 0 times, resulting in a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 57

Let's proceed to step 2:
61 divided by 57 is 1 with a remainder of 4.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 57 from 61, we get 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 57

On to step 3:
57 can be fit into 45 0 times, resulting in a remainder of 45.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 45 after subtracting 0 from 45.
Grab the next digit (2) from the dividend, add it to 45, then carry on: 452 / 57

Moving on to step 4:
57 can be fit into 452 7 times, resulting in a remainder of 53.
The next digit of our result is 7. 
Result so far: 107.0
Subtracting 399 from 452 leaves us with 53.
Include the next digit (2) from the dividend after 53, then repeat: 532 / 57

Moving on to step 5:
When dividing 532 by 57, we get 9 with a remainder of 19.
The next digit of our result is 9. 
Result so far: 1079.0
If we subtract 513 from 532, we 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 6:
57 goes into 190 3 times with a remainder of 19.
The next digit of our result is 3. 
Result so far: 1079.3
Subtracting 171 from 190 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 7:
The number 57 fits into 190 3 times, leaving a remainder of 19.
Use 3 as the next digit of our solution. 
Result so far: 1079.33
Subtracting 171 from 190 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.

The final result is 1079.33 with a remainder of 0.019.
