We look at the division of 57550724 by 684 
The aim is to understand the frequency of 684 in 57550724.

Going ahead to step 1:
5 divided by 684 is 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (7) of the dividend behind the 5 and repeat the process: 57 / 684

Let's proceed to step 2:
684 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 57 and we're left with 57.
Bring next digit (5) of the dividend behind the 57 and repeat the process: 575 / 684

Step 3:
684 can be fit into 575 0 times, resulting in a remainder of 575.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 575, we end up with 575.
Append the next digit (5) from the dividend to 575 and continue with: 5755 / 684

Advancing to step 4:
5755 divided by 684 is 8 with a remainder of 283.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 5472 from 5755 leaves us with 283.
Include the next digit (0) from the dividend after 283, then repeat: 2830 / 684

Going ahead to step 5:
684 can be fit into 2830 4 times, resulting in a remainder of 94.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
Subtracting 2736 from 2830 leaves us with 94.
Include the next digit (7) from the dividend after 94, then repeat: 947 / 684

Moving on to step 6:
If we divide 947 by 684, we get 1 and a remainder of 263.
Record the quotient 1 as the next digit in the result. 
Result so far: 841.0
Subtract 684 from 947 to get 263.
Bring next digit (2) of the dividend behind the 263 and repeat the process: 2632 / 684

On to step 7:
When dividing 2632 by 684, we get 3 with a remainder of 580.
Use 3 as the next digit of our solution. 
Result so far: 8413.0
If we take 2052 away from 2632, we end up with 580.
Include the next digit (4) from the dividend after 580, then repeat: 5804 / 684

On to step 8:
684 can be fit into 5804 8 times, resulting in a remainder of 332.
The next digit of our result is 8. 
Result so far: 84138.0
If we subtract 5472 from 5804, we get 332.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3320, and continue the process.

Going ahead to step 9:
3320 divided by 684 is 4 with a remainder of 584.
The number 4 becomes the next digit in our result. 
Result so far: 84138.4
If we take 2736 away from 3320, we end up with 584.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5840, and continue the process.

On to step 10:
When dividing 5840 by 684, we get 8 with a remainder of 368.
Put 8 as the next digit of the answer. 
Result so far: 84138.48
Subtracting 5472 from 5840 leaves us with 368.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3680, and continue the process.

Going ahead to step 11:
684 can be fit into 3680 5 times, resulting in a remainder of 260.
The next digit of our result is 5. 
Result so far: 84138.485
Subtracting 3420 from 3680 leaves us with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Advancing to step 12:
684 can be fit into 2600 3 times, resulting in a remainder of 548.
Use 3 as the next digit of our solution. 
Result so far: 84138.4853
Subtract 2052 from 2600 to get 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

On to step 13:
When dividing 5480 by 684, we get 8 with a remainder of 8.
The number 8 becomes the next digit in our result. 
Result so far: 84138.48538
The remainder is 8 after subtracting 5472 from 5480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 14:
The number 684 fits into 80 0 times, leaving a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 84138.48538
The remainder is 80 after subtracting 0 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 15:
When dividing 800 by 684, we get 1 with a remainder of 116.
The number 1 becomes the next digit in our result. 
Result so far: 84138.4853801
Subtract 684 from 800 to get 116.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1160, and continue the process.

Going ahead to step 16:
The number 684 fits into 1160 1 times, leaving a remainder of 476.
Use 1 as the next digit of our solution. 
Result so far: 84138.48538011
Subtract 684 from 1160 to get 476.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4760, and continue the process.

Our division results in 84138.48538011 with a remaining 4.76e-07.
