53899628 divided by 684 
The aim is to understand the frequency of 684 in 53899628.

Moving on to step 1:
When dividing 5 by 684, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 684

Let's proceed to step 2:
When dividing 53 by 684, we get 0 with a remainder of 53.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Fetch the next digit (8) from the dividend, attach it to 53 and continue: 538 / 684

Going ahead to step 3:
If we divide 538 by 684, we get 0 and a remainder of 538.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 538 leaves us with 538.
Include the next digit (9) from the dividend after 538, then repeat: 5389 / 684

Let's proceed to step 4:
The number 684 fits into 5389 7 times, leaving a remainder of 601.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
Subtracting 4788 from 5389 leaves us with 601.
Bring next digit (9) of the dividend behind the 601 and repeat the process: 6019 / 684

Step 5:
If we divide 6019 by 684, we get 8 and a remainder of 547.
The number 8 becomes the next digit in our result. 
Result so far: 78.0
Subtract 5472 from 6019 to get 547.
Fetch the next digit (6) from the dividend, attach it to 547 and continue: 5476 / 684

Moving on to step 6:
If we divide 5476 by 684, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 788.0
Deduct 5472 from 5476 and we're left with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 684

Moving on to step 7:
684 can be fit into 42 0 times, resulting in a remainder of 42.
Use 0 as the next digit of our solution. 
Result so far: 7880.0
If we subtract 0 from 42, we get 42.
Bring next digit (8) of the dividend behind the 42 and repeat the process: 428 / 684

Step 8:
684 can be fit into 428 0 times, resulting in a remainder of 428.
The number 0 becomes the next digit in our result. 
Result so far: 78800.0
Deduct 0 from 428 and we're left with 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Going ahead to step 9:
684 goes into 4280 6 times with a remainder of 176.
Write down 6 as next digit of the result. 
Result so far: 78800.6
Deduct 4104 from 4280 and we're left with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Going ahead to step 10:
1760 divided by 684 is 2 with a remainder of 392.
Record the quotient 2 as the next digit in the result. 
Result so far: 78800.62
If we take 1368 away from 1760, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Step 11:
684 can be fit into 3920 5 times, resulting in a remainder of 500.
The next digit of our result is 5. 
Result so far: 78800.625
Deduct 3420 from 3920 and we're left with 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Step 12:
5000 divided by 684 is 7 with a remainder of 212.
Record the quotient 7 as the next digit in the result. 
Result so far: 78800.6257
Subtract 4788 from 5000 to get 212.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2120, and continue the process.

Advancing to step 13:
The number 684 fits into 2120 3 times, leaving a remainder of 68.
Write down 3 as next digit of the result. 
Result so far: 78800.62573
Deduct 2052 from 2120 and we're left with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 14:
The number 684 fits into 680 0 times, leaving a remainder of 680.
Record the quotient 0 as the next digit in the result. 
Result so far: 78800.62573
Subtract 0 from 680 to get 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6800, and continue the process.

Step 15:
When dividing 6800 by 684, we get 9 with a remainder of 644.
Write down 9 as next digit of the result. 
Result so far: 78800.6257309
If we subtract 6156 from 6800, we get 644.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6440, and continue the process.

Going ahead to step 16:
When dividing 6440 by 684, we get 9 with a remainder of 284.
The number 9 becomes the next digit in our result. 
Result so far: 78800.62573099
Subtract 6156 from 6440 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Our division results in 78800.62573099 with a remaining 2.84e-07.
