We're dividing 543808 by 57 
The aim is to understand the frequency of 57 in 543808.

Advancing to step 1:
When dividing 5 by 57, we get 0 with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 57

Let's proceed to step 2:
When dividing 54 by 57, we get 0 with a remainder of 54.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 54 and we're left with 54.
Append the next digit (3) from the dividend to 54 and continue with: 543 / 57

Step 3:
If we divide 543 by 57, we get 9 and a remainder of 30.
Use 9 as the next digit of our solution. 
Result so far: 9.0
If we subtract 513 from 543, we get 30.
Append the next digit (8) from the dividend to 30 and continue with: 308 / 57

Advancing to step 4:
57 goes into 308 5 times with a remainder of 23.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
If we subtract 285 from 308, we get 23.
Include the next digit (0) from the dividend after 23, then repeat: 230 / 57

Advancing to step 5:
When dividing 230 by 57, we get 4 with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 954.0
If we take 228 away from 230, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 57

Moving on to step 6:
When dividing 28 by 57, we get 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 9540.0
Subtract 0 from 28 to get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Moving on to step 7:
When dividing 280 by 57, we get 4 with a remainder of 52.
Use 4 as the next digit of our solution. 
Result so far: 9540.4
Deduct 228 from 280 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 8:
The number 57 fits into 520 9 times, leaving a remainder of 7.
The next digit of our result is 9. 
Result so far: 9540.49
The remainder is 7 after subtracting 513 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 9:
If we divide 70 by 57, we get 1 and a remainder of 13.
Use 1 as the next digit of our solution. 
Result so far: 9540.491
If we subtract 57 from 70, we 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.

Going ahead to step 10:
If we divide 130 by 57, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 9540.4912
Subtract 114 from 130 to 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 11:
If we divide 160 by 57, we get 2 and a remainder of 46.
The next digit of our result is 2. 
Result so far: 9540.49122
Subtracting 114 from 160 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

The quotient of the division is 9540.49122, and the remainder is 4.6e-05.
