671188 ÷ 57 
The aim is to understand the frequency of 57 in 671188.

On to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 57

On to step 2:
When dividing 67 by 57, we get 1 with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 57 from 67 leaves us with 10.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 57

Advancing to step 3:
When dividing 101 by 57, we get 1 with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Subtracting 57 from 101 leaves us with 44.
Include the next digit (1) from the dividend after 44, then repeat: 441 / 57

Let's proceed to step 4:
57 goes into 441 7 times with a remainder of 42.
The next digit of our result is 7. 
Result so far: 117.0
If we subtract 399 from 441, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 57

On to step 5:
The number 57 fits into 428 7 times, leaving a remainder of 29.
The number 7 becomes the next digit in our result. 
Result so far: 1177.0
Deduct 399 from 428 and we're left with 29.
Fetch the next digit (8) from the dividend, attach it to 29 and continue: 298 / 57

Advancing to step 6:
57 goes into 298 5 times with a remainder of 13.
Record the quotient 5 as the next digit in the result. 
Result so far: 11775.0
Subtract 285 from 298 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

On to step 7:
57 goes into 130 2 times with a remainder of 16.
Put 2 as the next digit of the answer. 
Result so far: 11775.2
If we subtract 114 from 130, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 8:
57 goes into 160 2 times with a remainder of 46.
The next digit of our result is 2. 
Result so far: 11775.22
Subtract 114 from 160 to get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

After the division, we end up with 11775.22 and a remainder of 0.046.
