673216 divided by 57 
The aim is to understand the frequency of 57 in 673216.

Going ahead to step 1:
If we divide 6 by 57, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 57

Moving on to step 2:
57 goes into 67 1 times with a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 57 from 67, we get 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 57

Let's proceed to step 3:
When dividing 103 by 57, we get 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 57 from 103, we get 46.
Take the next digit (2) from the dividend and append it to 46, then repeat: 462 / 57

Going ahead to step 4:
462 divided by 57 is 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 118.0
If we subtract 456 from 462, we get 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 57

Going ahead to step 5:
61 divided by 57 is 1 with a remainder of 4.
Use 1 as the next digit of our solution. 
Result so far: 1181.0
Deduct 57 from 61 and we're left with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 57

Let's proceed to step 6:
46 divided by 57 is 0 with a remainder of 46.
Write down 0 as next digit of the result. 
Result so far: 11810.0
The remainder is 46 after subtracting 0 from 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
460 divided by 57 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 11810.8
The remainder is 4 after subtracting 456 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 8:
When dividing 40 by 57, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11810.8
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 9:
When dividing 400 by 57, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11810.807
If we take 399 away from 400, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 10:
If we divide 10 by 57, we get 0 and a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 11810.807
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 57 fits into 100 1 times, leaving a remainder of 43.
The next digit of our result is 1. 
Result so far: 11810.80701
The remainder is 43 after subtracting 57 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 12:
The number 57 fits into 430 7 times, leaving a remainder of 31.
The next digit of our result is 7. 
Result so far: 11810.807017
Deduct 399 from 430 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
57 goes into 310 5 times with a remainder of 25.
Write down 5 as next digit of the result. 
Result so far: 11810.8070175
The remainder is 25 after subtracting 285 from 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 14:
57 goes into 250 4 times with a remainder of 22.
Use 4 as the next digit of our solution. 
Result so far: 11810.80701754
If we take 228 away from 250, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

The final result is 11810.80701754 with a remainder of 2.2e-08.
