291200 ÷ 57 
The aim is to understand the frequency of 57 in 291200.

On to step 1:
The number 57 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 57

Moving on to step 2:
57 goes into 29 0 times with a remainder of 29.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 29 to get 29.
Bring next digit (1) of the dividend behind the 29 and repeat the process: 291 / 57

Let's proceed to step 3:
291 divided by 57 is 5 with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 285 from 291 leaves us with 6.
Grab the next digit (2) from the dividend, add it to 6, then carry on: 62 / 57

On to step 4:
62 divided by 57 is 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 51.0
If we take 57 away from 62, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 57

Advancing to step 5:
When dividing 50 by 57, we get 0 with a remainder of 50.
Put 0 as the next digit of the answer. 
Result so far: 510.0
Deduct 0 from 50 and we're left with 50.
Append the next digit (0) from the dividend to 50 and continue with: 500 / 57

Going ahead to step 6:
57 goes into 500 8 times with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 5108.0
The remainder is 44 after subtracting 456 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 7:
57 can be fit into 440 7 times, resulting in a remainder of 41.
The next digit of our result is 7. 
Result so far: 5108.7
Subtract 399 from 440 to get 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Going ahead to step 8:
410 divided by 57 is 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5108.77
Subtract 399 from 410 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Our division results in 5108.77 with a remaining 0.011.
