447868 ÷ 57 
The aim is to understand the frequency of 57 in 447868.

Step 1:
57 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 57

Going ahead to step 2:
When dividing 44 by 57, we get 0 with a remainder of 44.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 44, we end up with 44.
Take the next digit (7) from the dividend and append it to 44, then repeat: 447 / 57

Moving on to step 3:
If we divide 447 by 57, we get 7 and a remainder of 48.
Put 7 as the next digit of the answer. 
Result so far: 7.0
The remainder is 48 after subtracting 399 from 447.
Bring next digit (8) of the dividend behind the 48 and repeat the process: 488 / 57

Step 4:
When dividing 488 by 57, we get 8 with a remainder of 32.
The next digit of our result is 8. 
Result so far: 78.0
Deduct 456 from 488 and we're left with 32.
Bring next digit (6) of the dividend behind the 32 and repeat the process: 326 / 57

Moving on to step 5:
If we divide 326 by 57, we get 5 and a remainder of 41.
Record the quotient 5 as the next digit in the result. 
Result so far: 785.0
If we subtract 285 from 326, we get 41.
Append the next digit (8) from the dividend to 41 and continue with: 418 / 57

Moving on to step 6:
57 can be fit into 418 7 times, resulting in a remainder of 19.
Record the quotient 7 as the next digit in the result. 
Result so far: 7857.0
The remainder is 19 after subtracting 399 from 418.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Advancing to step 7:
The number 57 fits into 190 3 times, leaving a remainder of 19.
Write down 3 as next digit of the result. 
Result so far: 7857.3
If we subtract 171 from 190, 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.

Going ahead to step 8:
If we divide 190 by 57, we get 3 and a remainder of 19.
Record the quotient 3 as the next digit in the result. 
Result so far: 7857.33
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 7857.33 and a remainder of 0.019.
