304537 ÷ 57 
The aim is to understand the frequency of 57 in 304537.

Advancing to step 1:
When dividing 3 by 57, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 57

Moving on to step 2:
57 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (4) from the dividend, attach it to 30 and continue: 304 / 57

Step 3:
57 can be fit into 304 5 times, resulting in a remainder of 19.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 285 from 304 and we're left with 19.
Include the next digit (5) from the dividend after 19, then repeat: 195 / 57

Advancing to step 4:
When dividing 195 by 57, we get 3 with a remainder of 24.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 171 from 195 to get 24.
Take the next digit (3) from the dividend and append it to 24, then repeat: 243 / 57

Let's proceed to step 5:
The number 57 fits into 243 4 times, leaving a remainder of 15.
Record the quotient 4 as the next digit in the result. 
Result so far: 534.0
Subtract 228 from 243 to get 15.
Include the next digit (7) from the dividend after 15, then repeat: 157 / 57

On to step 6:
When dividing 157 by 57, we get 2 with a remainder of 43.
Use 2 as the next digit of our solution. 
Result so far: 5342.0
Deduct 114 from 157 and we're left with 43.
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 7:
When dividing 430 by 57, we get 7 with a remainder of 31.
Use 7 as the next digit of our solution. 
Result so far: 5342.7
If we take 399 away from 430, we end up 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 8:
The number 57 fits into 310 5 times, leaving a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 5342.75
Deduct 285 from 310 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Moving on to step 9:
The number 57 fits into 250 4 times, leaving a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 5342.754
Subtract 228 from 250 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Going ahead to step 10:
57 goes into 220 3 times with a remainder of 49.
The next digit of our result is 3. 
Result so far: 5342.7543
The remainder is 49 after subtracting 171 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 11:
The number 57 fits into 490 8 times, leaving a remainder of 34.
The number 8 becomes the next digit in our result. 
Result so far: 5342.75438
If we subtract 456 from 490, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 12:
57 goes into 340 5 times with a remainder of 55.
Record the quotient 5 as the next digit in the result. 
Result so far: 5342.754385
If we take 285 away from 340, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

On to step 13:
57 goes into 550 9 times with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 5342.7543859
The remainder is 37 after subtracting 513 from 550.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 14:
370 divided by 57 is 6 with a remainder of 28.
Use 6 as the next digit of our solution. 
Result so far: 5342.75438596
Deduct 342 from 370 and we're left with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

The quotient of the division is 5342.75438596, and the remainder is 2.8e-08.
